Local Chapters keep active during Covid

EAGE2020 delivers an optimistic ending to the year It was against the backdrop of a global health pandemic and subsequent downturn in the oil and gas industry that EAGE held its first ever online Annual event this past December.

to foster good discussion and the exchange of ideas amongst an eager geoscience community. In keeping with tradition, the conference centred around a robust technical programme featuring over 500

A forum session underway.

The meeting was previously rescheduled as an in-person gathering in December. When that turned out to be too much of a risk the eventual decision was to switch to an online format. This uncertainty and disruption kind of echoed the challenges being faced by members of the Association’s, caught up in an industry already facing long term concerns due to the demands for energy transition and climate change mitigation. In spite of the logistic challenge of delivering a full technical programme with simultaneous presentations, the Annual Meeting proved successful in being able

presentations. Many of the innovative presentations reflected the growing focus towards improving efficiency and value driven production. At the same time, a growing number of presentations in geothermal and CCUS reflected the opportunities for geoscientists in new business areas. The virtual format also saw the reimagining of some aspects of the conference. The usually busy exhibition floor was replaced with a virtual business space and a dedicated BizTalk presentation schedule. The Virtual Community Hub also offered a varied programme with opportunities FIRST

for networking, education, career development and student activities. Meanwhile, the newly created Hot Topic rooms also created a space for robust discussions with a technical focus on key topics such as FWI and Rock Physics. The Opening Session also proved to be a highlight of the conference. The hour-long programme started off with an interview with the EAGE Board in which President Everhard Muyzert stressed the importance of becoming an “association for all people with professional interests in geoscience problems that have an engineering aspect”. This was followed by the Crosstalk Conversations, hosted by EAGE Editor Emeritus Andrew McBarnet and featured many businesses and thought leaders in the industry including: Jon Erik Reinhardsen (Equinor), Sophie Zurquiyah (CGG), Jarand Rystad (Rystad Energy), Marc Gerrits (Shell), Scott W. Tinker (Switch Energy Alliance) and Joseba Murillas (Repsol). The segment managed to deliver an optimistic message in its exploration of the future for geoscience business and technology. The discussion reflected on the challenges of ensuring energy security and equity while balancing environmental sustainability and minimizing the impacts of all forms of energy. Marc Gerrits also reminded the geoscience community that as ‘the custodian of technical excellence in the subsurface’

it had a critical role to play in a cleaner energy future. The final day of the conference was fittingly capped off by the Forum Discussion on the ‘New Era of Geoscience’. The panel contributors all identified opportunities for geoscientists outside the oil and gas industry as the energy transition gains pace. But it was recognised that the idea of a traditional geoscience career may have to give way to a more flexible and multi-disciplined strategy. Whether schools and universities were catering for this eventuality was also a

moot point. During the discussion, Ellie Ardakani (Meta Innovation Technologies) reminded the audience of the importance of diversity and global recruitment as the best commercial strategy to ensure that all available talent is afforded a place at the table as we seek to solve some of the major challenges ahead. Reflecting further on the success of the event, Everhard said: ‘2020 has been a challenging year for all of us. The EAGE year concluded with a very busy and successful week with our largest events held both online: the Near Surface Geoscience and

the Annual conferences. Both events were a great success. I have seen some good quality presentations and participated in many lively technical and panel discussions. I must thank all our participants, speakers, panellists, chairs, exhibitors, sponsors and staff for all their contributions. While I look forward to meeting you in-person in 2021, the past year’s online experience has left a very good impression on me.’ The EAGE2020 Annual Conference Online was sponsored by: Shearwater, Schlumberger, Equinor, Sharp Reflections, TGS, Total, Chevron and Thermo Fisher.

Opening session.

The week of 7-11 December will always be remembered as the week in which EAGE delivered its two flagship conferences more or less simultaneously. Both were of course online as a result of the Covid-19 restrictions. Starting the week was the annual Near Surface Conference & Exhibition, combining three parallel conference programmes: the 26th European Meeting of Environmental and Engineering Geophysics, the 4th Applied Shallow Marine Geophysics Conference and the 3rd Conference on Geophysics for Mineral Exploration and Mining. Building on the earlier experience with online conferences such as ECMOR (14-17 September) and GET 2020 (16-18 November 2020) the big Near Surface meeting was organized through pre-recorded presenta4

tions, allowing delegates to engage with material before and after the conference. Doing so, sessions included faster paced presentation pitches followed by extended Q&A. The Technical Programme proved to be the engine behind the NSG conference, including 150 presentations encompassing traditional and emerging topics and technologies, including environmental and engineering geophysics; mineral exploration and mining; groundwater and archaeological studies; modelling, inversion and data processing; together with methods, applications and new developments. In addition to the varied programme, an assortment of additional activities was added to the online meeting, including a virtual exhibition where delegates explored the technologies, services and innovations

offered by international companies and organizations. Despite the move to online, it was still an opportunity to network with peers in the industry and make new contacts. Furthermore, a well-rounded opening and closing ceremony marked opportunities for the full community to gather, as well as the inclusion of the EAGE Happy Hour, during which delegates could take a bit of a break from the hard work that online conferencing is! The online conference had some happy unintended consequences. It allowed the core NSG community in the EAGE membership to reconvene. But also, with no need to travel and with access at the click of a button, online provided an opportunity to welcome delegates and contributions usually not present at NSG conferences. These included a series of strong interventions from KEGS (Canada) and SAGA (South Africa). We want to thank our first time attendees for joining the conference - hopefully, it’s the start of a new tradition for you! We look back at a positive online NSG Conference & Exhibition - something which was only possible through the support of our committees, volunteers, speakers and companies. We in particular want to thank those companies sponsoring the event: Equinor, BP and Applied Acoustic. We hope to see you again later this year, this time hopefully in person in Bordeaux for NSG 2021.

DUG DEBLEND

Blended surveys provide a number of operational and technical advantages. In the OBN example pictured above, three triplesource vessels were firing within 15 km of each other. Such overlapping shots must first be separated to permit subsequent processing. DUG Deblend is our inversion-based solution which can reconstruct shots as if they had been acquired separately. It generalises to a wide range of scenarios and can also simultaneously deblend seismic interference, which is simply an unintended form of blended acquisition. With DUG Deblend, there is no more separation anxiety. (Data courtesy of AGS and TGS)

Data science on agenda at first online regional conference in Russia & CIS Boris Belozerov (Gazpromneft NTC), chair of the meeting, reports on the First EAGE regional conference in Russia & CIS on data science in the oil and gas industry that took place on 19-20 October as an online event.

Participants in discussion.

This first conference focused on the main aspects of data analysis from the practical issues of machine learning application during exploration and extraction to the concerns of creating functional platforms for data analysis. The main distinguishing quality of the event was the focus on the practical aspect. We were able to learn how certain pieces of advanced intelligent data analysis technology can already work and bring results. In session ‘Applications and Use Cases of Machine Learning’, Andrei Koziaev (RN-KrasnoyarskNIPIneft) showed how machine learning tools are used in complex geological sections of Eastern Siberia. Alexander Butorin (Gazpromneft NTC) demonstrated how the application of random forest technology, comparatively simple in its execution, can be used for interpreting the results of wavefield inversion. A huge spark of interest was produced by a report from Vladimir Bulaev (NPF Geofizika) on the use of neural networks for compression of geophysical data. There were not many accounts showcasing the practical tools of unconventional geological modelling. Our next conference will pay more attention to this, because the value lies precisely in correlating all data in the early stages of field exploration into some coherent, 8

geologically grounded field models - this is one of the most important challenges in front of us and the industry as a whole. The extended keynote by Sabine Klarner touched upon a wide range of topics and showed how important it is to approach the choice of data analysis tools reasonably and cautiously. Machine learning tools are not always more effective than traditional methods. Most importantly, it is necessary to pay attention to the data that we use and take into account the representativeness, quantity and the models that we use for the final analysis. The papers presented in the session ‘Automation, Robotics for E&P’ revealed a wide spectrum of automation applications. We all see that there is a process (it has already begun) of transferring data storage and processing to cloud systems, although in the oil and gas industry it is

difficult due to the fact that often the data is proprietary with security involved. The second challenge is the development of the application of machine learning methods for automated interpretation and correlation. This will allow automating all these processes, speeding them up, accelerating decision-making, and eliminating the human factor. The third direction of research development is building digital twins. There is a lot of talk about this, but it is not always clear what this is, i.e., in the form of interaction of some objects, in the form of processes, or the interaction of these processes with other processes. Of interest is that complex 3D models are being built, for example, of the geological environment, and on a large scale at the field level, and at the level of regions, which includes the so-called multi-physics approach. At the same time, insufficient attention is focused on how these models are validated and how they reflect reality. Nevertheless, such systems are being built and even applied. During the session ‘Data analytics and machine learning’, several interesting algorithms for solving specific problems were presented. Of note were the presentations on the application of Bayesian algorithms (Petr Andriushchenko, ITMO University), a very interesting algorithm for comparing seismograms (Antonina Arefina, Gazprom Neft), comparison of

algorithms for predicting thermal conductivity (Anuar Shakirov, Skolkovo Institute of Science and Technology), predictions of explosive disjunctions based on potential fields using neural networks, GIS clustering, and the use of stochastic methods for petrophysical modelling. When we look at what is being done in the industry and what is being done in Russia, we are only starting to move from the process of studying and getting to know machine learning tools to systematizing and creating the correct generalized picture of methods, tools and architectures of certain applied things in intelligent analysis. We are heading towards compli-

cation and the creation of a hierarchical classification system that would allow the transition from ‘narrow’, applied artificial intelligence to a broader, more versatile AI that can analyze metadata about the task and about data types and select the most optimal network architectures. The value from all this is an increase in quality, and, probably, the ability to integrate more data, reducing risks and uncertainties. We are introducing within the wide community of the universities we work with, among our young specialists, the idea that, in general, the paradigm of competencies of a modern petroleum engineer or an exploration

engineer is changing dramatically. Data mining tools, modern programming languages, frameworks that allow you to make better mining tools are becoming a reality. This is a competence that should become one of the main ones when recruiting an oil and gas engineer in future. Experts will begin to devote more time to advanced analysis, rather than integration, data fusion, etc. The Data Science in Oil & Gas conference was initiated by the EAGE Local Chapter Tomsk-Krasnoyarsk-Novosibirsk and conducted by the EAGE Russia & CIS office. The next conference is scheduled for 4-6 August 2021 in Novosibirsk.

Paris LC discusses prospects in post-Covid oil and gas world There could hardly have been a more topical webinar than the last one organized in November by the EAGE Local Chapter Paris entitled ‘Upstream Oil & Gas Industry Covid-19 Aftermath’. Speakers, Marine Simoën, IRIS associate research fellow and Pierre Hacquard, analyst and petroleum Geoscientist, Equinor, explored the impacts of the Covid-19 outbreak on the upstream oil and gas industry and its potential consequences on oil supply and demand over the next years. A focus was put on current

industry trends in exploration, investments, geopolitical tensions that could disrupt supply security as well as the US onshore industry that accounted for 60% of oil supply growth over the last decade. Conclusions were drawn on the capability of the industry to face and evolve. Their presentation reached 70 attendees around the world with very enthusiastic feedback on the insights provided. LC Paris is happy to share a recording of the webinar, published on the EAGE YouTube channel under the EAGE Com-

munities playlist. To receive news on future events by the EAGE Local Chapter Paris, follow their LinkedIn page (www. linkedin.com/company/eage-local-chapter-paris/) and drop us an email to paris. localchapter.eage@gmail.com if you would like to become a member.

Perm was ideal venue for engineering and mining geophysics event

Brainstorm session.

The year 2020 will be remembered among the most ill-fated periods of recent history, but it still has had its silver linings. One such was the 16th Conference and Exhibition Engineering & Mining Geophysics 2020 held on 14-18 September in Perm, Russia alongside Engineering and Mining Geology 2020 Workshop. Perm was chosen to host the event for several reasons. The city was established following the discovery of copper deposits in Permian sandstones in the 17th century. The name Perm gained world renown thanks to Scottish geologist Roderick Murchison, who announced the Permian system in the name of the city in 1841. In the early 20th century, the discoveries of oil and potassium salt deposits in the Permian strata made Perm Krai one of the most significant regions in terms of mineral resources. In addition to oil and potassium-magnesium salts, the deposits of diamonds, gold, and several less flashy mineral raw materials were discovered in the region as well. Advanced geophysical methods are the keystone of safe and efficient natural resource development. The largest mining enterprises of the region, such as URALKALI, Eurochem Usolskiy potash plant, and Verkhnekamsk Potash Company have geoscientific services of their own to support the operational exploration stage.

recent advancements in the hardware and methodological framework of geophysical studies to predict structural features of the rock mass and estimate the effects of the development process on its properties are of unconditional interest for production geophysicists. Perm is a major industrial centre with a population of over one million people, and like any other large urban industrial agglomeration has various problems that

karst development, as well as the presence of a branching network of historical workings in copper sandstones. These natural and anthropogenic engineering-geological hazards are rather common outside Perm Krai as well. The biggest threat is associated with the operating mines, where both types of hazards are present at the same time. It is apparent that the problem of ensuring safe and healthy natural resource development on territories with such complex engineering-geological structure requires new science-based technical solutions in the field of engineering geophysics. Most participants at the conference agreed that the brainstorm session to cover these main issues was a success and that the results produced would stimulate significant progress in coming up with solutions and help Perm Krai and other mining regions make the development of natural wealth safer and more effective. The event gathered over 150 specialists from all over Russia with both in-person and online participation options available to the participants. The event was on par with meetings in pre-pandemic years in terms of submissions with a total of 148 papers presented within 16 scientific sessions. The conference also

Optimizing project turnaround performance is now a major preoccupation EAGE is to hold a first online workshop on Optimizing Project Turnaround Performance (OPTP) between 22-24 February 2021. Tony Martin, geophysical advisor, PGS and chair of the workshop, describes what’s in store for participants. There are a number of reasons why reducing the turnaround time between seismic data acquisition and delivery to the interpreter’s workstation is so important in today’s industry. Primarily it allows us to revise or change a business model. On the contractor side, the less time it takes to complete a project, the more can be undertaken, leading to improved revenue. Enhanced competitiveness may also result in the same. Additionally, newly developed techniques that accelerate turnaround may upgrade results and create new opportunities. On the operator side, the quicker data delivery happens the more time is available to the interpreters to analyze the data, make decisions on further development, drill or drop an exploration acreage and for the company to realize potential ROI. OPTP stands for Optimizing Turnaround Project Performance. Whilst there is a strong incentive and desire to accelerate data delivery, the workshop will cover anything that may help or achieve that, and that is both significant in scope and diverse in nature. So, whilst there is an undeniable interest in optimizing turnaround, trying to attract attention to such a vast scope is challenging. With hindsight, it might have been better to focus on singular components. The

other challenge is that many associates accelerated turnaround as either having consequences for data quality, or be the realm of machine-learning techniques, and on both accounts, this is not true.

Tony Martin, workshop chair.

The workshop covers one of the hot topics in the industry, but as that topic is in itself diverse, a participant should be updated on a range of innovations and technologies that they can take away with them to implement in their own day-to-day business. As the subject is varied, so are the keynote, invited and submitted papers and speakers. They represent a cross-section of both our geoscience industry, and the data science business. The same can be said of the organizing committee, which has leading

academics chief geophysicists, renowned researchers, geophysical advisors and prominent data scientists. Their broad experience has enabled and attracted both an exciting and interesting collection of papers, as well as a format that will allow plenty of open and constructive discussion. I would highlight that geoscientists are at the pinnacle of data science. Nobody knows how to manipulate, move, order, reorder, apply processes, check and validate data better than we do. The collective experience of geoscientists in our industry is an invaluable asset, and we are the best source of ideas for developing pragmatic solutions to the challenges we face, like trying to accelerate data delivery – we do not always need to look elsewhere. Our community needs to be reminded of this.

Registration for the workshop is still open and you can benefit from a discounted fee up until 7 February 2021. Learn more about the event and register on the event website, via events.eage.org.

Geomodel 2020 makes the most of reduced circumstances

Plenary session presentation.

The annual Geomodel conference in Gelendzhik is a well-known platform for presenting new innovative technologies for processing and interpretation of geological and geophysical data, as well as examples of solving practical issues in geological exploration and development of oil and gas fields in various regions. Attendance at this year’s 22nd edition was significantly hit due to Covid-19. Even so, more than 100 representatives from 60 companies and universities, such as LUKOIL, Rosneft, Gazpromneft STC, NOVATEK STC, Rosgeologia, Schlumberger, Baker Hughes, CGG, LUKOIL-Engineering, INGG SB RAS, VNIGNI, Moscow State University, Gubkin Russian State University of Oil and Gas and many others took part in the conference that was held in a hybrid format. More than 80 papers were presented in 15 oral and poster sessions and including a round table discussion dedicated to neural network technologies and machine learning. I.I.Priezzhev, professor at Gubkin Russian State University of Oil and Gas and chair of the conference Organizing Committee captured the topic of the moment with his discussion on ‘Neural networks and other machine learning algorithms and 14

In this regard, the best and most interesting paper in the session was the presentation on the use of the phenomenon of tectonic tension for the generation of hydrocarbons and the possibility of identifying new zones of hydrocarbon accumulation.’ According to Boris Enikeev (Pangea), the most interesting point was the discussion of the efficiency of sludge usage, as well as papers on zeolites and permittivity. Dmitry Danko (Gubkin Russian State University of Oil and Gas) said: ‘There has been a clear trend towards the integration of a large amount of geological and geophysical information when interpreting seismic data. Also, much attention is paid to assessing the accuracy and verification of the obtained results, especially in well-studied fields.

The question is debatable, but, no doubt, it will find a response in production activities.’ Mikhail Denisov (GEOLAB) noted: ‘The observed trend in seismic data processing is increasing the accuracy of depth constructions by using the most modern and advanced processing algorithms, among which tomographic inversion and full-wave seismogram inversion should be noted. If not so long ago geophysicists almost always performed processing and imaging in the time domain, now the emphasis is on deep constructions, which is more correct and more accurate. This is in line with the latest global trends. Such a processing strategy requires the construction of depth-velocity models of the environment, which is a separate and non-trivial task.’ Vladimir Bondarev (USMU) said: ‘Due to the exceptional importance of obtaining the most plausible seismic images of the geological environment, this line of research in seismic exploration will continue to occupy a leading place in the work plans of theoreticians and practitioners. It can be expected

Mikhail Zubkov (West Siberian Geological Centre), chairman of the session on fracturing and fractured reservoirs, observed: ‘By means of physical and mathematical modelling we can understand the patterns of formation of fractured zones in order to use the obtained patterns to predict fracture zones, their length, orientation in space to search for the most productive areas of hydrocarbons and the subsequent organization of the optimal scheme for their development. Additional experimental and theoretical material is needed in order to increase the diversity of structural forms that form destruction zones of different morphology. With the help of tectonophysical restoration of the geological environment, it is possible to identify zones of predicted increased fracture density and simulate fracturing that occur in certain deformation conditions. This will make it possible to more reasonably plan geological exploration, as well as the development of hydrocarbon fields with fractured reservoirs.’ EAGE and the organizing committee look forward to seeing participants at Geomodel 2021, the 23rd Oil and Gas Exploration and Development Conference, which will take place 6-10 September 2021, and will address a wide range of issues from geology to field development. Abstracts are accepted until 20 May 2021.

What’s ahead for seismic acquisition and imaging discussed at LC Netherlands meeting

Q&A session underway.

Panos Doulgeris writes: Another online event was successfully organized by EAGE Local Chapter (LC) Netherlands in November themed ‘The future of seismic acquisition and imaging: Some perspectives’ featuring talks by Gerrit Blacquière and Eric Verschuur. The event was also viewed by members of the LCs of London, Aberdeen, Oslo and Paris, of the DOGS-Delft and RWTHAachen student chapters, and of the Oslo Society of Exploration Geophysicists. Main themes of the night were the role and nature of geophysics during and after the energy transition period as well as the transformational role of artificial intelli-

gence to the field. The latter was backed up by a number of examples presented by the two speakers. In the first talk, Gerrit Blacquière pointed the direction of seismic exploration to robotization of acquisition and the automation of processing and characterization. He explained that the trend in the industry has always been the acquisition of more data. He anticipated that recent developments will lead to the development of smarter processes that will deliver more information from less data. Blacquière presented two cases to support his view: deghosting and low-frequencies reconstruction by using machine learning techniques. Although this technology is in its early days, he reported that the results obtained are deemed encouraging and further work will be performed in this direction. During the second talk, Verschuur focused primarily on extracting all the available information from the measurements by taking a more holistic approach towards seismic processing. Presented as

case studies, the adoption of surface and interbed multiples for imaging complement perfectly the use of diving waves by Full Waveform Inversion and diffractions by diffraction imaging. Going one step further, incorporating multi-physics measurements, e.g., gravity or electromagnetics measurements, could potentially address remaining uncertainties about the subsurface. Concluding that geophysics and seismic will still have a central role in ongoing subsurface exploitation activities, he remarked that artificial intelligence can potentially be a very powerful tool with a direct impact on every stage of seismic processing. At the end of the two presentations, a Q&A session took place where the two speakers could address the questions from the audience. A digital recording of the event talks is available on the EAGE Communities YouTube channel, at www. youtu.be/pYluVXSQcJk.

Prize start for Czech Local Chapter The EAGE Local Chapter (LC) Czech Republic was launched in Prague in January 2020 with great plans and aspirations thanks to the work of 14 founding EAGE members from the Prague area. Among them were employees of private companies, research institutions and government institutions covering a wide range of interests from seismology geology including basin modelling, gravity and near surface geophysics. This naturally brought some challenges in organizing something interesting for the entire local community, but the overall discussion was positive and we planned field trips, lectures, invited speakers and bowling.

When Covid-19 came into the picture, we re-evaluated our goals. Despite the restrictions, we were able to organize two fascinating webinars. The LC also accepted the opportunity to organize jointly with the commercial company Seismik a competition for the best Master’s or Bachelor’s thesis, known as the ‘Seismik Prize’. The competition had been run by Seismik since 2012, but the LC was able to give the award a new meaning and life. It believes that the event provides an opportunity to attract new young professionals to become EAGE members and motivate the future geoscientist to join our group.

Value of the rock physics approach is topic of LC London evening

Texture of reservoir rock.

Nick Huntbatch, quantitative interpretation product manager of Ikon Science, was guest speaker at London Chapter’s evening talk in November 2020. During the webinar Huntbatch told us about the modern use of powerful seismic reservoir characterization techniques to enhance details of both subsurface architecture and it petrophysical properties. The understanding of the rock physics is based on well data that after quality control and conditioning are used for petrophysical interpretation of distinct lithofacies units. Upscaling is required for building impedance and amplitude

models of the subsurface. The response from these models is then compared with the surface seismic data. The elastic properties and AVO response for different saturations are estimated with some uncertainty dependent on seismic bandwidth, available angle range, noise and rock property overlap. The prior knowledge of facies and per-facies rock physics trends is a key link between geology and geophysics that allows predicting the subsurface and capturing uncertainty in geological properties and in the data. The rock physics driven approach facilitates a better understanding of res-

ervoir geometry and plumbing, and ultimately provides the gateway to building better, more accurate property models of the subsurface. This lecture was the seventh webinar organized by EAGE Local Chapter London in 2020 attracting a global audience to our local online activities. Recording of the talk is available on the EAGE’s YouTube channel. EAGE Local Chapter London acknowledges Artem Kashubin of PetroTrace, Bingmu Xiao of CGG, Lok Lee of Schlumberger, Celina Giersz of Shearwater and, of course, Nick Huntbatch of Ikon Science for arranging this event.

Global oil and gas discoveries outperform expectations to top 10 billion boe in 2020 Despite concerns that Covid-19 could drive down discovered volumes to their lowest levels in decades, found resources in 2020 are already confirmed to be more than 8 billion barrels of oil equivalent (boe) and were projected to reach 10 billion boe by the end of the year, according to research from Rystad Energy. About 3.75 billion boe, or 46% of total discovered volumes, are gas while liquid volumes are estimated at 4.31 billion boe. Yet-uncounted resources in finds such as Sakarya in Turkey point to additional upside, meaning that 2020 will avoid returning to the multi-decade low seen in 2016 at just 7.7 billion boe. The 73 new discoveries announced this year (through to October) are evenly split between land and sea with 36 onshore and 37 offshore. Russia leads the way in terms of discovery volume, with 1.51 billion boe, while Suriname comes second with 1.39 billion boe and the UAE follows third with 1.1 billion boe. Of the offshore volumes, which account for slightly more than three-quarters of discovered resources, 33% was found in ultra-deep waters, 38% in deepwater areas and 29% in shallow waters. ‘Global oil and gas operators will chase plenty of additional volumes in wildcats planned for the final two months of the 2020, although some may not

be completed until early 2021 and will therefore add to next year’s tally. We believe discovered volumes are likely to settle at around 10 billion boe,’ said Palzor Shenga, senior upstream analyst at Rystad Energy. Oil and gas companies’ exploration plans have included prospects with higher chances of success in mature areas, as well as high-risk, high-reward wildcats in frontier regions, resulting in some game-changing offshore discoveries. Companies have experienced exploratory success in emerging plays in countries including Suriname, Guyana, South Africa and Turkey, as well as in proven mature regions such as Brazil and Norway. Ranking companies by discovered volumes shows that Russia’s Gazprom is in the lead, ahead of Total and Apache. The latter two have found around 960 million boe and 700 million boe respectively of net recoverable resources this year, mainly thanks to three major discoveries in Block 58 off the coast of Suriname. ‘We expect that only about 4.5 billion boe of the 8 billion boe discovered so far this year will be produced by 2040, and in coming years annual discovered volumes are likely to settle at a new normal of around 10 billion boe per year,’ said Rystad. ‘We see two main reasons for this trend. First, oil and gas players are streamFIRST

lining portfolios and exploration strategies and will scrutinize prospects more closely than before, thereby reducing the number of wells that will be drilled. A more stringent selection procedure for drill-ready prospects means that only the ones with the highest chance of success will see a spinning drillbit. ‘Second, companies will be less willing to drill high-risk wells in environmentally sensitive frontier areas, both for financial and environmental reasons. As a result, the full petroleum potential of areas such as the Alaskan Arctic, Foz do Amazonas in Brazil and the Barents Sea may never be unlocked. Rystad said it also expected improved data access and digitization would help operators pinpoint successful prospects with more accuracy. Increasing access to data and the growth of digital platforms will enable exploration teams to rapidly discover and access basin-scale data, and manage exploration opportunities using data sharing across multi-disciplinary teams, it added. ‘Increasing use of digitization will reduce costs and make exploration procedures more standardized, and data sharing and collaboration means each operator will need to drill fewer wells to understand the subsurface. This will lead to higher productivity per well drilled,’ Rystad said.

TGS starts three 3D surveys offshore South America

Geoscience atlas of offshore Ireland is completed

TGS has started the Malvinas 3D programme offshore Argentina and is planning two seismic surveys offshore Brazil. Offshore Argentina, the BGP vessel Prospector will acquire approx. 5000 km2, which will bring the total coverage in the area to 18,000 km2. The survey is expected to be completed in Q1 2021. Offshore Brazil, TGS will mobilize the COSL vessel HYSY720 to commence acquisition of the Espirito Santo 3D survey by the end of the year. This is a Dual Azimuth (DAZ) survey covering a 1400 km2 area in the Espirito Santo Basin. The vessel is currently in transit to Brazil and acquisition is expected to be completed by the end of Q1 2021. TGS also plans to commence a 7000 km 2D survey in the Pelotas Basin during Q1 2021. The Pelotas 2D programme will have depth imaged products available in early Q3 2021, in time for the 17th Brazil licensing round. The new data set will complement the existing TGS 2D data coverage in the area and allow for better prospect mapping. The survey will be acquired in partnership with BGP, using its vessel Pioneer. The delayed start of these three projects has led TGS to revise its annual investment guidance for 2020 down from $325 million to $300 million. Kristian Johansen, CEO at TGS, said: ‘Latin America is one of our key focus areas and despite the challenging market conditions, our clients are continuing to support our projects in this region.’

Merlin Energy Resources Limited has completed the first comprehensive stratigraphic map of offshore Ireland. ‘The Standard Stratigraphic Nomenclature of Offshore Ireland: An Integrated Lithostratigraphic, Biostratigraphic and Sequence Stratigraphic Framework’ comprises a large-format illustrative Atlas, which documents new lithostratigraphic, chronostratigraphic, biostratigraphic and sequence stratigraphic frameworks for the drilled Phanerozoic section of the Ireland offshore region. The database for the study included all legacy stratigraphic data from 264 released wells and boreholes. In addition, a number of UK wells that are close to the median line with Ireland have been tied to the evaluations. Furthermore, a significant amount of new biostratigraphic data was generated by additional sample analysis from key wells and intervals. A total of 309 lithostratigraphic units (groups, formations, members, units) are described and illustrated by type and reference wells, distribution maps and ties to seismic data. Nearly 200 new lithostratigraphic names are introduced in the Atlas. Correlations and comparisons are made between the newly defined offshore Ireland stratigraphy and that of the UK offshore, UK onshore, North Sea and offshore Eastern Canada regions. As a result, UK lithostratigraphic nomenclature has been applied to offshore Ireland rock units, where subsurface contiguity can be demonstrated. Sixty-three previously existing names are utilized from the UK. An extensive database of 3D and 2D seismic data was interpreted, leading to the recognition of a set of 60 consistently defined and named seismic horizons. These are illustrated in a set of 10 regional seismic lines and 55 figures showing seismic to well ties across the region. In addition, the seismic evaluation, combined with gravity data interpretation, has led to a revision of the structural elements for the region.

A regional evaluation of source rock potential has identified 21 formations with hydrocarbon generation potential based on the newly developed stratigraphy. The 16 proven hydrocarbon reservoir units in all known fields and discoveries offshore Ireland are formally named and described, and their distributions mapped. The atlas was commissioned by the Irish Shelf Petroleum Studies Group (ISPSG) and has been developed by a consortium led by Merlin Energy Resources Ltd, incorporating Palaeodate Ltd, Network Stratigraphic Consulting Ltd, Riley Geoscience Ltd, Integrated Geochemical Interpretation Ltd and Dunford Exploration Ltd. The Atlas is being made freely available by Ireland’s Department of Environment, Climate and Communications. All maps generated in the project are available in an ArcGIS database. Dr Philip Copestake, project manager and Atlas editor, at Merlin said ‘Merlin Energy looks forward to using the atlas and accompanying databases as the foundation for future subsurface interpretations offshore Ireland, whether for natural resources evaluations, academic investigations or as the basis for reservoir definition and mapping to support energy transition projects such as carbon capture and storage.’ Clare Morgan, head of technical section, Petroleum Affairs Division, at Ireland’s Department of Environment, Climate and Communications described the atlas as ‘a reference tool for all geoscientists working Ireland’s offshore basins, whether industry, researchers or government-based and this unique document will be utilized for many years and decades into the future. As Ireland moves away from hydrocarbons to offshore renewable energy development, the repurposing of the knowledge from the oil and gas industry to the renewable energy industry, such as provided in this study, is hugely beneficial.’

PGS releases X Viking Graben 2020 survey data

PGS’ Ramform Vanguard completed the survey in the summer.

First data is available on PGS’ GeoStreamer X Viking Graben 2020 survey. In the summer of 2020 PGS acquired advanced offset- and azimuth-rich data, which is contiguous to the GeoStreamer X Viking Graben 2019 survey. ‘PGS has addressed illumination challenges in this area with a single vessel towing a highly efficient, dense receiver spread,

record-wide sources to capture ultra-near offsets, and several long streamer tails that provided longer offsets for optimal FWI at depth. The first results are available just three months after acquisition and the GeoStreamer X data quality is very good,’ said Gunhild Myhr, VP new ventures at PGS. The area is known for its prolific source rock and good-quality reservoirs.

Late Jurassic rifting led to the formation of numerous horst and rotated fault blocks along the margin of the Viking Graben. Targets range from Eocene injectites, deep marine fans, fluvial deposits and weathered basement. Illumination challenges in the area are associated with sand injectites, often cemented, with anomalously high velocities (so-called ‘v-brights’), as well as large, complex shallow channels and gas at various levels. Improved imaging will also make it possible to better assess injectites with reservoir potential. Julien Oukili said: ‘This fast-track PSDM volume delivers higher image-clarity and better subsurface illumination. Work is ongoing with the full integrity imaging, which will enhance in particular demultiple, 5D regularization, and velocities, to provide optimal illumination and resolution.’ The survey was completed July 2020 and final PSDM results will be available in Q2 2021.

CGG wins reprocessing contracts offshore Malaysia CGG has won two large-scale complex seismic reprocessing contracts from PTTEP covering two regions offshore Malaysia. The company will conduct merged reprocessing of surveys from many vintages, including towed-streamer and OBC seismic data from offshore Sabah and Sarawak. The fast-track products are expected by mid-next year and final workstation products will be delivered by the end of 2021. The images are expected to improve the definition of producing reservoirs, enable enhanced planning and drilling of future wells, and open up new plays for near-field exploration at deeper intervals. This region has a complex highly faulted subsurface where scattered gas bodies

mask the target reservoir on existing data sets. To unmask the gas wipeout, remove distortions at the reservoir level and image the bounding faults, CGG will apply its latest workflow including proprietary imaging technologies, such as high-frequency full-wavefield Time-Lag FWI (HF-FWI), Q-compensating least-squares (LS-Q) Kirchhoff PSDM and LS-Q RTM, which have been fine-tuned over many similar projects in the region. These technologies will also be focused on improving imaging of the deeper exploration targets with enhanced amplitude, resolution and continuity in the mini-basins and improved definition of the steeply dipping folds underneath the main unconformity.

Meanwhile, CGG has won a threeyear contract extension from Petroleum Development Oman (PDO) to continue providing land seismic imaging services at its dedicated processing centre (DPC) in Muscat. The company will continue to implement its latest proprietary algorithms to bring step-changes in the imaging of the ever-growing volumes of land data, characterized by complex near-surface conditions and strong multiples. CGG will also aid PDO’s transition from cable to node multi-source acquisition and the incorporation of machine learning into its workflows.

PGS starts next phase of Campos deepwater survey offshore Brazil PGS has started acquisition of the latest phase of the Campos Deepwater GeoStreamer X, a prefunded multiclient 3D seismic survey with multi-azimuth coverage. In December PGS started to acquire an additional 8400 km2. The vessel Ramform Titan is being configured with 14 multisensor streamers, each 10.05 km long, the largest spread ever towed offshore Brazil. This configuration minimizes the number of source points per square kilometre and reduces the number of acquisition days, said PGS. This survey will provide the first 3D seismic data over blocks offered in the upcoming 17th Bidding Round, now scheduled for October 2021.

The Campos Deepwater GeoStreamer X project combines new and legacy 3D data delivering long-offset, multi-azimuth seismic data over the deepwater portion of the northern Campos Basin. The survey area includes presalt open acreage adjacent to Albacora and Marlim Leste fields and areas acquired and under contract in the 14th Bidding Round, with drilling operations underway to test large presalt structures. The tailored acquisition configuration for the GeoStreamer X project will provide 10-km long offsets to improve depth velocity modelling accuracy of the postsalt, salt, and presalt sections, facilitated by the use of full wave-form inversion.

FWI modelling results indicate these long offsets will aid in derived velocity accuracy in the presalt section. These additional offset data also promise added angle range and improved signal/noise for seismic amplitude analysis and reservoir characterization. Multi-azimuth processing and velocity model building will improve illumination and image quality of the subsurface structures found within the presalt play in this portion of the Campos Basin. Phase 1 imaging will be available in Q1 2021, providing final multi-azimuth products over open pre-salt acreage, including TTI Kirchhoff and RTM (45 Hz) PSDM products.

Shearwater wins contract for 3D survey offshore Senegal Shearwater Geoservices has won a large towed-streamer 3D acquisition and fasttrack processing project offshore Senegal for client Total.

TGS completes processing of 3D US onshore surveys TGS has completed the final processing products for the high-resolution Canton and Gloss Mountain 3D surveys onshore US. The projects encompass approx. 2895 km2 in the Major, Woods and Blaine counties in the Anadarko Basin. Historical production in this area comes from stacked pay horizons ranging from the Ordovician Arbuckle to the Pennsylvanian Marmaton Group. Current targets include the Hunton, Woodford, and multiple zones within the Mississippian. The processing flow is AVO-compliant to maintain true amplitude. It is suitable for rock property and attribute generation: prestack AVO inversion, azimuthal analysis and spectral decomposition. Phase and amplitude treatment will ensure accurate reservoir analysis, said TGS.

in a logistically challenging area for resource exploration, said CGG. A specially modified aircraft equipped with CGG’s proprietary Full Spectrum Falcon airborne technology will simultaneously collect the gravity gradient, gravity, and magnetic

data, for interpretation by CGG’s experts based in Perth, Australia. The goals of the survey are to understand the sedimentary thickness of the Cuvette, and identify prospective structures using the low-noise Full Spectrum Falcon data. It is estimated that the Cuvette could contain sediments up to 9-km thick, but with no modern data collected in the basin this will need to be verified. Geophysical data in the basin to date consists of 2D seismic data acquired mostly along the Congo River in the 1950s and 1970s as well as an airborne gravity and magnetic survey in the 1980s. Greg Paleolog, senior vice-president, multi-physics, CGG, said: ‘The Cuvette Basin could be considered one of the last provinces in Africa to potentially hold giant to supergiant oil and gas accumulations.’

Rystad predicts global E&P investment of $380 million in 2021 Investments from global exploration and production companies in 2021 are projected to reach around $380 billion, almost flat year-on-year, according to research from Rystad Energy. About 20% or $76 billion of the estimated 2021 investments could be at risk of deferral or reduction, with the remaining amount being categorized in the safer tiers of low and medium-range risk. Investments may rebound to the pre-crisis level of $530 billion by 2023 if oil prices rise to around $65 per barrel – though Rytsad warned that after the previous market crisis in 2014, annual E&P investments never recovered to the pre-crisis level of about $880 billion and instead settled at $500 billion to $550 billion. Much of that reduction was due to supply chain and efficiency improvements, leaving little scope for further

such reductions this time around, said Rystad. Instead, E&P players are pulling other levers to weather this market downturn, such as deferring infill drilling programmes, projects’ FIDs and start-ups, reporting significant write-offs on stranded assets, and reshaping their portfolios. ‘As E&Ps are also speeding up a transition into low-carbon energy, it is possible that this time, too, upstream investments will not return to pre-crisis levels in the long-term, even if they do recover somewhat over the next few years,’ said Olga Savenkova, upstream analyst at Rystad Energy. Of the total $380 billion of projected investments, about 60% ($234 billion) is likely to come from producing assets, which have two main spending channels: facility and well capex. Within facility capex, about 38% will be spent on facility maintenance. This is believed to be

a low-risk category, as operators were forced to postpone most of their planned maintenance programmes in 2020 due to coronavirus restrictions and lower oil prices. Maintenance work will therefore have high priority in 2021. Shallow hazard high-resolution prestack time migration products will also be available, to aid in shallow drilling hazard analysis, along with gravity and magnetic data for regional basin analysis. Martin Melhuus, PGS vice-president sales and services for South America, said: ‘Despite the challenges of this year, the support of industry funding for this programme shows there is strong interest in the potential within the Campos Basin. Available fast-track results show great promise and reveal large presalt structures within the available acreage.’ The survey will bring PGS’s coverage in the area to approximately 14,900 km2.

Hydrogen projects could boost $400 billion service industry, says Rystad A wave of green and blue hydrogen projects in coming years could unlock about $400 billion worth of spending for the service industry between 2020 and 2035, research from Rystad Energy industry has revealed. Of the total pipeline, Rystad has projected that about 30 gigawatts (GW) of green hydrogen capacity is expected to be operational by 2035. Several blue hydrogen mega-projects are also being discussed at present. Of the $400 billion worth of investments, transport and infrastructure will account for $130 billion, facility construction $120 billion, equipment costs $70 billion, while engineering costs and

maintenance, modifications & operations (MMO) will amount to about $25 billion each. ‘At present, hydrogen projects, especially green hydrogen, are centred in Australia and Europe. In Asia, meanwhile, Japan and Korea are looking into importing hydrogen and developing international supply chains, especially within transportation. Hydrogen is also expected to feature in China’s forthcoming five-year energy plan, as well as in the plans presented by provincial authorities in the country,’ said Audun Martinsen, head of energy service research at Rystad Energy. In Europe, a group of 11 gas infrastructure companies has come up with

a proposal for the development of EU hydrogen infrastructure starting with key renewable energy regions in Europe, such as the North Sea. Under the proposed infrastructure strategy, a 6800 km pipeline network will need to be built by 2030 to facilitate transportation. For hydrogen storage, large-scale storage locations – salt caverns, aquifers or depleted hydrocarbon fields – will be needed, involving either locations already in use for other purposes or developing new ones. Storing and retrieving hydrogen in this manner will require the drilling of a large number of wells – both injectors and producers.

0.4. million tonnes of green hydrogen production in 2030 and 1 million tonnes of green hydrogen production by 2040. This could abate 8 to 10 million tonnes of CO2 emissions – equivalent to the yearly emissions from road traffic in Norway. ‘Hydrogen will add to the competitiveness of renewables in the years to come by adding value and an alternative route to market for renewables,’ said Pål Eitrheim, executive vice president New Energy Solutions in Equinor. Equinor said that northwest Europe is well positioned to develop an integrated hydrogen value chain – from offshore wind development and renewable power generation to production, storage, transport and the sale of green hydrogen. ‘The North Sea has a great potential for large-scale wind development, there is extensive existing natural gas infrastructure that is suitable for storage and large-scale transport of hydrogen, and there are large industrial clusters in the Netherlands and Germany as well as heavy-duty vehicle OEMs that could economically benefit from a ‘first mover’ advantage,’ the company said.

US shale spending and output to keep declining in 2021 US shale oil output has declined by 3.1% to 7.5 million barrels per day (bpd) in 2020 from 7.7 million bpd in 2019, Rystad Energy estimates. In 2021 shale oil output is estimated to decline further by 2-3%. US operators’ D&C capex, which was $98.7 billion in 2019, will more than halve in 2020 to $45.2 billion. Operators’ have now shifted focus towards preserving as much output as possible while implementing capital efficiency measures, which means 2021’s capex is projected to decline 7-9% year on year. Rystad Energy has also analysed the third quarter guidance of 23 companies, which together account for about 41% of this year’s US shale oil production. Inter-

preting the companies’ released guidance, their 2021 onshore oil production will likely shrink by 1.9% while D&C capex will be 12.9% lower compared to the group’s stated 2020 plans. When the plans of larger producers and private operators are added to the analysis, capex decline will likely be lower, at 7-9%, and output cuts larger. ‘Amid a second wave of Covid-19 in North America and Europe, and uncertainty related to potential new regulation the industry may face once a new US administration settles in, operators largely remain disciplined. They aim to increase cost efficiencies and spend only the minimum amount needed to prevent next year’s output from declining too much,’

said Alisa Lukash, senior analyst at Rystad Energy. Permian-focused operators will cut spending by about $1.6 billion, or 16% below this year’s target. Operators with a presence across multiple basins will follow suit, with an $800 million, or 11%, spending decrease. Bakken-focused peers will cut spending by $200 million, or 9%. Despite the fact that operators in the Permian Basin are leading capex reduction efforts, the group has guided an almost 2% increase in oil output in 2021 compared to 2020. The factors driving this drastic cost reduction per barrel include service cost reductions and the price deflation of components.

The Seismic Campaign for Geothermal Energy in the Netherlands (SCAN) has collected its 1000th kilometre of data in the municipality of Laarbeek (North Brabant). SCAN has been examining the Dutch subsurface for the future use of geothermal energy since the summer of 2019. It is evaluating resources in areas of the Netherlands where there has so far been insufficient data available. Energie Beheer Netherlands (EBN) and TNO have been conducting the programme on behalf of the Ministry of Economic and Climate Affairs. The survey has now visited more than 130 municipalities. Approximately 16,000 holes have been drilled, nearly 200,000 geophones installed and more than 148,000 hours worked in the field. The seismic survey is expected to continue until the end of 2021. Gitta Zaalberg, programme manager of geotechnical operations at EBN, said that preparations were now being made for scientific drilling. I

US to make provision for more Arctic drilling The US government has pledged to make it easier to explore Arctic regions in US waters. The US Department of the Interior’s Bureau of Safety and Environmental Enforcement and Bureau of Ocean Energy Management is to issue an Arctic Exploratory Drilling Proposed Rule to remove ‘unnecessary, burdensome provisions’ while ensuring that energy exploration on the Arctic Outer Continental Shelf (OCS) remains safe and environmentally responsible. ‘As countries like Russia increase their presence in the Arctic – including the use of US technologies to develop their seabed resources, it is increasingly important to ensure that the United States has a strong presence in the Arctic OCS,’ said deputy secretary of the inte-

rior Kate MacGregor. ‘The Beaufort and Chukchi Seas have a long legacy of oil and gas development – we believe these proposed revisions will better harness new technological innovation and best science to allow for responsible domestic energy development off the coast of Alaska.’ Executive Order 1375 directed the Department of the Interior to review the 2016 Arctic Exploratory Drilling Rule and to report recommendations. To date, there have been 37 wells completed in the Chukchi and Beaufort Seas. The proposed rule leaves 36 out of 65 provisions from the original Arctic Rule unchanged. Ten provisions were identified as appropriate for revision, and 12 provisions were added to maintain safety and environmental protection on the OCS.

Wells could be drilled in the Chukchi and Beaufort Seas.

Sercel launches seismic tool to monitor buildings Sercel and Apave have launched AP’Structure, a structural health monitoring solution. The solution will enable operators to monitor the integrity of entire buildings and infrastructure in real time, receive warnings about irregularities and prolong the life cycle of the infrastructure. AP’Structure deploys S-lynks, a newly launched autonomous wireless solution from Sercel for measuring structural vibration.

With its embedded ultra-sensitive QuietSeis sensor, S-lynks can measure a structure’s ambient noise. The wireless system is self-sustaining and can be deployed on all types of structures. The recorded data is then streamed to the cloud for processing and is immediately accessible for remote analysis. Apave’s engineers and technicians will carry out expert analysis and interpretation of the recorded monitoring data using proprietary algorithms. This

dynamic data is used to understand the behaviour of a structure, monitor its deterioration over time, trigger alerts if anomalies are detected that are not visible to the naked eye, and propose corrective measures. Philippe Maillard, Apave CEO, said: ‘AP’Structure will enable operators to monitor the integrity of buildings and structures in real time so that they can anticipate and prioritize maintenance operations and prolong their life cycle.’

While conventional sources vary their energy in one direction versus another, this project’s omni directional source is designed to give out energy uniformly in all directions which will be key to 4D repeatability for this azimuth deepwater OBN acquisition, said Shearwater.

Chevron has announced its 2021 capital spending programme of $14 billion and lowered its longer-term guidance to an annual $14 to $16 billion through to 2025, lower than its previous guidance of $19 to $22 billion, which excluded Noble Energy. As investment is expected to decrease for a major expansion in Kazakhstan, the company will increase investments in the Permian, other unconventional basins, and the Gulf of Mexico.

Seabird makes move into deep-sea marine mining Seabird Exploration has diversified into deep-sea mining after announcing plans for funding and listing of its new subsidiary Green Minerals AS (GM). ‘Green Minerals will enable the world’s drive towards electrification and digitization in a sustainable manner. We do this by deep-sea mining of marine minerals and rare earth elements (REE) key to the green shift, eliminating the social costs in onshore mining while reducing the environmental footprint and solving a strategic need for the EU and USA,’ SeaBird said. Green Minerals has raised $13 million by issuing 2.8 million shares in the new venture. Seabird has retained ownership of 77% in the company. Green Minerals

will seek listing on Euronext Growth Oslo in Q1 2021. ‘Some of the largest shareholders in Seabird, the executive chairman and at least one board member have pre-committed to subscribe to the offering,’ SeaBird said. Medium-term, the company is looking to win licences to survey, explore and produce marine minerals on the Norwegian Shelf, capitalizing on what it says is a $77.8 billion resource potential. Long term, Green Minerals said its goal is to win mining licences internationally, based on its Norwegian Shelf technology, and establish the company as a leading offshore miner globally.

EMGS has won a 3D CSEM and MT (magnetotelluric) multi-client survey in the Gulf of Mexico. The contract from an existing client represents the first project for this customer in the Gulf of Mexico.

Oilfield services market to shrink by $340 billion The oilfield services (OFS) market, including seismic services, is projected to lose $340 billion in purchases over the next eight years as peak oil demand arrives earlier and at a lower level than previously thought, according to Rystad Energy research. The Covid-19 pandemic’s effect and the accelerating energy transition last month impelled Rystad Energy to revise its peak oil demand forecast to 2028, two years earlier than previously expected, at 102 million barrels per day, down from earlier projections of 106 million barrels per day. OFS purchases are expected to drop to $473 billion this year from $625 billion in 2019 and remain flat in 2021 before starting a slow recovery. ‘Based on our updated peak oil demand forecast we now see OFS purchases returning to pre-pandemic levels only after 2024 in nominal terms, reaching $642 billion in 2025,’ said Rystad. ‘With a lower need and willingness among E&P companies to invest in oil and gas, capital expenditure across offshore, shale and conventional onshore resources will probably struggle to get back to 2019 levels,’ said Audun Martinsen, head of energy service research at Rystad Energy. ‘In nominal terms, offshore investment levels are projected to return to 2019 levels in 2023, with conventional onshore following suit in 2025 and shale in 2028. In real terms, however, investments in upstream oil and gas may never make it back to 2019 levels.’ The service market is now estimated to grow at a compound annual rate of 7.9% from 2020 to 2025, compared to 10.4% in previous forecasts. The biggest revision to service purchases comes from the engineering, procurement, production and installation (EPCI) segments, where lower sanctioning activity has had a negative impact, but segments related to wells have also suffered due to the slowdown in the shale sector. 34

Danish CO2 storage project clears regulatory hurdle

Hod illustration; Source: Aker BP

The mission to store CO2 beneath the Danish North Sea has cleared its first

major hurdle after the chosen subsea reservoir was confirmed feasible for CO2 injection by independent certification body DNV GL. The certification of feasibility issued by DNV GL concerns the Nini West reservoir operated by Ineos, which is leading the Project Greensand consortium in partnership with Wintershall Dea and Maersk Drilling. DNV GL confirms that the Nini West field is conceptually suitable for injecting 0.45 million tonnes of CO2 per year per well for a 10-year period,

and that the subsea reservoir can safely contain the CO2 in compressed form. The Geological Survey of Denmark and Greenland (GEUS) acts as research partner to the project and is in the process of performing laboratory experiments of core material from the actual Nini West reservoir. Project Greensand hopes to have the first well ready for injection from the Nini platform in 2025. Longer term, the ambition is to develop the capacity to store approx. 3.5 million tonnes of CO2 per year before 2030.

Special Topic

LAND SEISMIC Land seismic systems continue to develop to facilitate ever more channels as well as cableless systems to ensure that efficient acquisition can take place in all terrains and with very little down time. New developments are also making systems more hard wearing so that they can operate at higher temperatures and in harsher environments. More sophisticated kit, including increasing use of drones, is facilitating larger surveys with longer sweeps. Hugo Vieytes provides a synthesis on the exploration of hydrocarbons in the Perdanales Salt Flat, II Region, Atacama, Chile. Jerzy Trela et al discuss recent advances in seismic nodal technology that have resulted in improved operational efficiency due to the reduction in size, weight, and increased field endurance of nodes and demonstrate why there is an urgent need to develop new quality standards for the next generation seismic data based on autonomous nodes. Tim Dean et al examine an extensive set of node test results from several recent nodal surveys to determine just how reliable modern nodes are. Spencer L. Rowse examines the factors that determine the transfer of energy from the source mechanism to the seismic signal Clark, R. Gruenwald et al describe the largest European single season data acquisition project successfully accomplished in challenging operational conditions in South Eastern Romania. Nicolas Tellier et al present data-supported comparisons between two sensors and discuss their impact on final imaging. Payton, S et al present a multi-physics approach that does not suffer from velocity-depth ambiguity and provides a robust shallow velocity model.

FEATURE: WHATSUP!

New Year’s Resolutions In this third WhatsUp! feature, Peter Rowbotham offers New Year’s Resolutions for geoscientists. A new year gives the opportunity for new resolutions, but also time to reflect. Let me offer you these two thoughts; given how much you have dedicated to studies or projects in 2020, surely what you have learnt deserves to be shared for the benefit of others? And looking back, can you think of any occasion when you regretted publishing or presenting something? Contrast that with regrets about not publishing those projects which never quite made it to completion, the ideas you had to leave behind when starting a new job or taking a career break, the data sitting orphaned on floppy disks or exabytes? Resolution 1: make insights available to others in 2021 through technical papers, conference presentations or online content. Visual communication A picture is worth a thousand words. As geoscientists and engineers, this is particularly true for us and the way we see and consider the earth. How often have you gazed down at the beach at low tide and marvelled at sedimentary processes in action, or looked up at the sky to see patterns redolent of seismic waves? The sight of a farmer planting, harvesting or ploughing in race track mode brings to mind seismic acquisition, with trees or telephone poles his or her equivalent of our platform obstructions (Figure 1). Our ‘swathe/swath’ of acquisition comes from an Old English/West Germanic word, which in Middle English denoted a measure of the width of grassland covered by a sweep of the mower’s scythe (Figure 2). Continuing on the theme of the agricultural/geoscientific link, might I suggest you search for ‘Remote Sensing of Crop Lodging storymaps’ by Sugandh Chauhan. Before reading this, I knew next to nothing about satellite imaging of crops, what lodging meant (although I’ve

seen it often enough in my local fields), or how the skills I have as a geophysicist could transfer across directly to agriculture. With a broad audience in mind, Dr Chauhan has explained the why, what and so what of the research being undertaken. To paraphrase a primary school saying ‘If a job’s worth doing, it’s worth doing (and talking about) well.’ Resolution 2: explain work in such clear terms. Publishing with First Break If the resolutions so far have persuaded you to write a paper, allow me to make a pitch for this publication. First Break sits in the camp of mass media rather than learned journal, and for that reason the potential readership is large, but only if you catch their attention. The importance of figures in that role cannot be stated enough, and I relish those technical paper submissions to First Break with the fewest words and the best figures. Resolution 3: always give figures the attention they deserve. As for writing, there are many guides available to how best to communicate with your audience, and for starters I would refer you to A Scrutiny of the Abstract by K.K. Landes and A scrutiny of the Introduction by J.F. Claerbout. The abstract is not a summary – it is your elevator pitch. Use it to motivate the reader to continue. The introduction should follow ‘Review, Claim, Agenda’ but save the reader’s patience and our printing costs/your membership fee by listing only the key papers that you would personally recommend that the reader follow up. The easy parts are the method and results, the main pitfall here being a chronological listing of everything that was done. Focus on the new — if what you have done is what everyone would do, save your breath and say ‘in the standard way’. The following comments about results, discussion and conclusions were made to an author in a recent review, and provide useful pointers for future contributors: • The results are too light — you have produced some interesting maps but there is no discussion of the results. • Together with a more detailed results section, the paper needs a discussion — somewhere to offer the reader some greater insights from your experience with this study. Where were the problems, was any special attention needed, where could improvements come in the future? • The conclusion could offer more than a summary of what has been done. What has been concluded? Have you achieved everything you set out to do?
