Geophysical Prospecting Special Issue on cost-effective mineral exploration planned for 2019 publication

Members of the EU Horizon 2020 project Smart Exploration are involved in an upcoming special issue of Geophysical Prospecting on ‘Cost-effective and innovative mineral exploration solutions’. Papers are currently being invited for the planned publication in 2019. The objective is to report on the remarkable progress being made in overcoming the perceived high exploration cost of mineral exploration particularly at depth. This is especially significant in the EU and in regions with thick cover requiring new and much more sensitive exploration technologies for direct deposit targeting. These challenges are evident from initiatives within the EU (e.g., Smart Exploration), Canada

(e.g., Metal Earth), Australia (e.g., CRC projects) and Africa, all regions where favourable geology exists but exploration is challenging when it coming to finding new ‘tier 1’ deposits at depth (+ 500 m). The journal intends to present an overview of the state-of-the-art and current challenges, including reappraisal of legacy data and ways to increase their value, new prototypes for maximizing the use of existing mining facilities, emerging high-density data acquisition systems, and advanced modelling/ processing algorithms covering direct deposit targeting and/or better understanding of mineral systems.

How to make an impression with your abstract for EAGE events In the run up to the EAGE Annual 2019, and our next Near Surface Geoscience Conference and Exhibition 2019, we have invited some experts to offer their advice on how to submit an attractive abstract to our events. In this article, Esther Bloem, a long-time contributor to EAGE events and publications, and a member of our Near Surface Division, outlines the steps required for putting together an abstract. First-time submitters should find this particularly useful. A more comprehensive version of her tips on how to prepare a great paper can be found on the EAGE website at www.eageannual2019.org. Before you start Choose the most relevant EAGE event at which to present your research. You can find information on the different events on the EAGE website, eage.org. Which events are relevant for your chosen topic? When is it on? What kind of audience are you trying to reach? Make a plan Writing an extended abstract is not done in just one hour. Think of a couple of important details, e.g., when is the deadline for submission? To prevent last minute problems, try to submit early, at

least 24 hours before the deadline is recommended. Go through the online submission to check what requirements are needed besides the abstract, like authors names, title, summary, keywords, etc. Make sure to download the abstract template early, so what you create meets the requirements exactly. Let the writing begin Write down the message you would like to present. This is the objective of your abstract. Think of the aspect of your research which you would like to present. On which aspect of your research would you like to get feedback? What is the most groundbreaking result(s) you have? What will your audience be interested in? Normally for a single article, there can only be one basic message. So keep it simple and avoid readers becoming confused. Select the right figures These visually show the message of your study. A figure can sometimes tell more

than 1000 words. Make sure to check that the figures are legible at print size. Esther Bloem adds: ‘I hope this helps to get you started! For more advice, and details on how to get the different sections of your extended abstracts just right, check out the website (see above) where I explain the importance of solid materials and methods (M&M) and much more’.

Workshop outlines options for better adapting to the era of low cost exploration Joint workshop chairs Jan Helgesen and Terje Dahl (Equinor) sum up the proceedings of the workshop at the EAGE Annual Meeting on â&#x20AC;&#x2DC;How exploration is adapting to a low cost environmentâ&#x20AC;&#x2122;. The workshop series was initiated at the 2017 EAGE conference in Paris following an initiative from Total. The objective is to identify practices and ways, including collaborative actions, to boost exploration and appraisal activities globally. Since 2014, most oil companies have cut into their discretionary exploration budget resulting in a drastic drop in geophysical and drilling activities, as well as human resources. An organizing committee with broad industry participation was established for the workshop series. The 2018 edition in Copenhagen attended by 100 participants discussed on experiences since the Paris workshop, cross-border collaboration in the North Sea and how to regain the health of the seismic industry. The morning session focused on actions from the workshop in Paris last year. It started with a report from the cross-industry exploration workshop in Cancun Mexico, which was very successful. This type of workshop should also be considered for other countries. This was followed by Total, Tullow and Equinor presenting successful examples of cost-sharing between oil companies in seismic acquisition, including group shoots and joint operated surveys across several licences. This has potential to be utilized further. Wood Mackenzie then presented a benchmark on exploration and production

activities among oil companies from 2014 to 2017, followed by a session covering North Sea cross-border exploration collaborations. In the panel discussion between Norwegian and UK authorities (NPD and OGA), the seismic contractor industry (PGS) and oil companies (Total and Equinor), it was suggested to improve cross-border collaboration and co-ordination. Particularly sharing rig and seismic acquisition plans between operators to reduce cost where possible. Unifying regulations between Norway and UK was also discussed, but it turned out to be challenging, and probably not necessary. The afternoon session focused on the unhealthy situation in the seismic supplier industry. Following the dramatic oil price drop in 2014, the marine seismic market has been characterized by over-capacity, low and unsustainable prices, and less appetite among oil companies to pay an uplift for technology. Seismic contractors are struggling to survive, and the sustainability of the current business model is being questioned. At the workshop, a panel with executives from operators and seismic suppliers addressed the path towards a more sustainable seismic industry. This included how contractors and oil companies can collaborate to reduce waste and develop the technology that is needed for a sound and value-creating exploration business. The session was facilitated by Equinor, and

opened with a keynote from WesternGeco followed by a short presentation from each panellist (PGS, CGG, BP and Total). Important conclusions and actions were: 1) Standardization of audits and HSE qualifications from operators. This action is being followed up by IAGC and was due to be raised at the IAGC HSE forum meeting in Stavanger in September 2018; 2) Operators need to clearly communicate the usefulness and value of new seismic acquisition technology before big investments are made; 3) Operators should include value of technology in tender evaluations; 4) Some operators communicated a shift towards more OBS acquisitions in mature areas like the North Sea; 5) There was a consensus among operators and some of the contractors that more collaboration is needed for development of new acquisition technology like marine vibrators. However, there is no tradition for such collaborations; and 6) The industry is moving towards more multi-client acquisition, which implies collaboration and cost-sharing. The organizing committee will discuss how these actions can be followed up. Also the intention is to continue this effort with one yearly workshop linked to the annual EAGE Conference and Exhibition. If you would like to contribute or participate, save the date for the London EAGE 2019 event (June 3-6).

Call for papers opens for workshop on giant carbonate fields of the Middle East

Abu Dhabi landsape.

Mark you diary for the first EAGE Workshop on Characterization and Workflows for Giant Carbonate Field Developments of the Middle East being organized by the Middle East Chapter of EAGE on 18-21, February 2019 in Abu Dhabi, United Arab Emirates. The goal of the workshop is to bring together a diverse group of professionals from across industry and academia to share ideas and address, in a multi-dis-

ciplinary way, the numerous challenges in dealing with these complex carbonate reservoirs The Middle East is home to the world’s largest carbonate reservoirs and optimizing their development is an important objective for everyone involved with these fields, but carbonate reservoirs are often difficult to model statically as well as dynamically due to high levels of reservoir heterogeneity, irregular porosity distributions and complex permeability barriers. Traditional seismic data and standard seismic analysis techniques alone are generally inadequate for creating robust models of these reservoirs. Fortunately, individuals in industry and academia are continuously coming up with creative new ideas to tackle the challenges posed by these important reservoirs. Too often, however, these ideas are not broadly recognized or shared with others facing the same challenges. To meet the aim of this workshop, the technical committee is seeking enthusiastic participants who will submit abstracts and

share their work as a starting point for further learning and discussion. The workshop will cover a broad range of topics, including: Depositional, diagenetic and sequence stratigraphic models for carbonates; Outcrop analogues and definition of geobodies in the subsurface; Petrophysical characterization of carbonates (rock typing, neural networks, permeability prediction); Rock physics modeling in carbonates; Fracture characterization and the impact on field development; Seismic reservoir characterization of carbonates; Advances in carbonate reservoir modeling; and Reservoir simulation of carbonate fields. The four days of the workshop will include oral and poster presentations, breakout sessions, and a core display. The workshop will also include a short course on Carbonate Reservoir Characterisation and Modelling, and two field trips: Carbonate Systems Developed in Active Tectonic Settings, Jebel Hafeet, and Coastal Sabkha Systems, Abu Dhabi. Delegates can choose to attend the short course or one of the field trips. See EAGE website for details.

Porto meeting provided productive time to promote EU opportunities EAGE’s EU Affairs Department was kept fully occupied at the Near Surface Geoscience Conference and Exhibition (NSG) in Porto with a booth to look after, a special guest to host and a site visit! It was all part of its mission to promote the Department’s EU services for members and its role as dissemination lead for the Smart Exploration Project which focuses on cost-effective, environmentally-friendly tools and methods for geophysical exploration. Highlight of the event was the hosting of Dr Marcin Sadowski, head of the Raw Materials sector at the Executive Agency for Small and Medium-Sized Enterprises (EASME) of the European Commission (EC), who is responsible for research and innovation projects of EU Horizon 2020 projects involving raw materials. Dr Sadowski’s visit was initiated by the EU Public Affairs team as part of its role, shared with Swedish partner Ludvika Kommun, for the dissemination, exploitation and civil society engagement of the Smart Exploration project. Event participants had an excellent opportunity to learn about and discuss the raw materials programme and more generally what is happening in Brussels. As such academics, researchers, SMEs, global companies and many others at NSG Porto were able to benefit. Dr Sadowski opened the Sunday workshop devoted to the Worldwide

and assess its characteristics and advantages. After the main event a second two-day geological seminar on the Western Baikal region wrapped up the meeting. According to the reviews we received, the conference was considered as comparable in value to equivalent events overseas. This is very significant from both economical and strategic points of views. It can help to improve and draw more attention to the new evolving subjects, problems and technologies which are poorly understood in the region due to lack of information available. The fact that fruitful discussions followed almost every presentation proves the rising interest in the conference and Baikal region in general. A typical observation of the conference’s value came from А.G. Vakhromeev. He said ‘The main tendencies in drilling and hydrocarbon exploration are development of the procedures to assess the complex fluid saturated reservoirs; production of hard-to-recover resources; enhanced oil recovery, inspection and prevention of asphalt, resin, and paraffin deposits; development of multilateral drilling technologies, enhancement of intelligent systems of drilling and production. The fact that all these technological developments

are focused on the fields of Russian Arctic Shelf and Northern Siberia is of great importance’. According to Т.V. Olneva, Gazpromneft, ‘The most impressive part was a tour to geo-electric test site. It inspired my desire for further exploration. Next time I will pay even more attention to what our contracting geophysicists have to say. It can be stated that the general interest towards the region remains at a high level. The analysis of its potential is being approached with a broad range of up-to-date methods and technologies’. The event was not without controversy, according to V.А. Kolesov, Institute of Fossil Fuel Geology and Production: ‘The hot issue of the session was the presentation by a representative of Gazpromneft-STC on an integral interpretation of e-data acquired using high-end geophysical well logging methods. It provoked rather heated discussions. That was because Schlumberger, which holds a monopoly with its own hi-tech interpretation methods, was publicly challenged by a Russian company!’ At the conference TNG-group presented the results of the implementation of a mobile NMR platform that allows for core exploration for quick identification of the prospective sedimentary intervals of superviscous oil. This work may be of high commercial value for the region when it comes to more reasonable identification of the intervals for further perforation.

Geological tour underway.

A presentation by Skoltech was devoted to thermal petrophysics, one of the recent trends in the science. The report was appraised as the best in the session for many participants who recognized the practical value of the subject discussed. Moreover, it was a good example of Russian technologies that have just entered the market. There were two reports on geonavigation using boundary delienators. Regardless of the high costs of the LWD method, it allows for a proactive navigation and, therefore, decreases the level of errors due to pressure maintenance, structural uncertainties, etc. Moreover, the method increases the success of well drilling within a reservoir interval. These presentations were followed by avid discussions.

During the same session, the performance of an electromagnetic microscanner was demonstrated being used for the first time in Eastern Siberia. The advantage of the method is that it allows working in boreholes filled with oil-based mud. The results obtained are very promising and may increase the further usage of this method in the subsurface of Eastern Siberia. In conclusion, we would like to thank the organizers of GeoBaikal 2018 and our sponsors who support and promote the ideas of the geophysical community. We also thank all the participants who contributed to this event that is vital not only for the development of Eastern Siberia and the Russian Far East, but of Russia itself. Till our next meeting on the shores of Baikal in the year 2020!

Success stories from WGE e-Mentoring programme With the conclusion of the 2018 Women in Geoscience and Engineering (WGE) e-Mentoring programme, the committee of the WGE Special Interest Community report on its evaluation of the initiative and its view of the way forward. This was the second edition of the programme. It consists of six months of one-to-one exchanges between EAGE members. There were 40 EAGE members from 18 different countries who took part embracing a high variety of profiles which were carefully reviewed by the WGE Committee.

The selection of mentors and mentees took multiple aspects into consideration including candidates’ professional background, interests, expertise level and goals. The feedback revealed a general appreciation for the quality of the matching from both mentors and mentees’ side. 80% of the participants who responded FIRST

programme shortly after moving to a new country, and my mentor helped me better understand how things work here.’ The overall programme ran from March to September 2018. Some participants considered this timeframe too short and advised that it should be extended to one year in the future. However, 100% of the responders also stated that they plan to keep in touch with their mentor/ mentee, indicating that the programme was successful in projecting benefits beyond the scheduled six months and to create long lasting links. In the words of one for the mentors, ‘It is a wonderful experience, you get a chance to know people who truly enrich your life’. One of the challenges of running a successful mentoring programme is to ensure that pairs stay in touch and develop a fruitful connection. The majority of the participants reported satisfaction with the frequency of the exchanges with their mentors/mentees (80% of the responders considered the frequency of their interactions completely appropriate). This translated into at least one regular interaction per month for 80% of the participants. Furthermore, the analysis of the results showed that the quality of the exchanges was generally much appreciated: 73% of the replies indicated that the interactions with mentors/ mentees produced constructive input for

A particularly rewarding aspect of the programme is that both mentees and mentors could benefit from it. ‘It is a process where you must give yourself beyond the technical aspects, a personal and continuous challenge. It is something not usual in a work environment’, noted one of the participants adding, ‘although I have been a mentor, I think it is a two-way process and I have learnt a lot from my mentee’s experience’.

Most connections took place over e-mails, Skype and phone but at least six participants arranged for faceto-face meetings. 80% of the responders also reported that their mentors/ mentees responded quickly to their messages so overall we can conclude that the interest of the participants remained constant and the commitment from both sides could satisfy the expectations, with some cases going the extra mile that secured long-lasting links on both personal and professional level. ‘I loved being in contact with my mentee’, wrote one of the mentors. ‘I learned a lot from her as she is on the operator side while I work in a service company’. One mentee commented: ‘My mentor was helpful, encouraging and our chats ranged over quite a lot’. Another said: ‘It was brilliant to be able to run through ideas with someone who had once been in my position’. Future improvements will include increased engagement of the EAGE community and support aimed at more structured interactions throughout the entire programme. The Committee has been sharing some stories to highlight the achievements of the programme and encourage others to join our Special Interest Community, which operates as a permanent platform of support, knowledge-sharing and networking for all.

Local Chapters meet in London for seismic history matching presentation Paul Mitchell, president of Local Chapter Aberdeen, came to London on 26 June to give a presentation on 4D Seismic History Matching at the Imperial College of London. The occasion was the result of a collaborative effort between our London and Aberdeen Chapters. There was a good turnout despite the rival attraction of an England World Cup match. Happily the result proved every bit as interesting as the soccer. Paul Mitchell (TAQA) gave his SPE Distinguished Lecturer presentation introducing the process of using 4D seismic data in addition to production data to history match reservoir models. Production data is temporally dense with near constant recording but spatially sparse. Conversely, seismic data is temporally sparse but spatially dense. Therefore, they complement each other well, filling in the missing information for each other. To emphasize the lack of industry utilization of 4D seismic history matching Mitchell estimated that the annual spend on 4D seismic surveys is $1-2 billion globally, but there are very few projects in

the literature, implying we are not getting the full value out of the 4D seismic data. There followed a case study of a 4D seismic history matching application on the Harding and Gryphon fields in the North Sea. Much of the total oil has been produced for these fields, so they are planning for the gas development stage, where they will start to produce the gas caps. Seismic surveys have helped to plan for this phase of the fields, but there is a complex network of sub seismic injectites above the reservoir, known from well logging. This method used to plot this network was trial and error using ad hoc methods. However, 4D attributes

extracted from the seismic can be used to derive quantitative, automatic and intelligent results. Looking to the future, Mitchell discussed the status of the technology and some research and development directions. He concluded that greater computing power will be required for finer scale models. Furthermore, he emphasized the need for more complex methods of petro-elastic modelling, for more robust methods for separating saturation and pressure, the need for geomechanical and overburden effects to be integrated into seismic history matching more often, adding that there is a need for more cost-effective frequent repeat seismic surveys. Finally, he stated that there is a need for more quantitative, automatic and intelligent methods for 4D seismic history matching. The evening ended with some very interesting questions and a drinks reception for further discussion and socializing. It was a great opportunity for connecting communities and growing the network of local professionals. For more evening lectures and collaborations, contact your closest Local Chapter!

Professor Landa provides diffraction imaging insights to Aberdeen and Dublin LCs

Prof Landa delivers his lecture on diffraction imaging

Local Chapters in Aberdeen and Dublin were hosts in September to a fascinating lecture by Prof Evgeny Landa, EAGE Education Tour instructor, who currently works at Tel Aviv University and as a lead R&D advisor for PetroTrace. Prof Landa presented the theory and practical application of diffraction imaging. This is an area where he has been at the forefront of research since completing his PhD in 1986. The presentation started with a discussion on the historical

context of diffractions and proceeded to recent examples of high resolution diffraction images of the subsurface across several geological regions. His enlightening talk emphasized the physical meaning of the phenomenon and provided the general geophysics audiences with a great overview of the challenges and successes in this field of seismic imaging. He described how the technology helps to image and locate small-scale discontinuities in the subsurface such as faults, reefs and fractures.

For EAGE LC Ireland, this was their second event and was held at the Dublin Institute of Advanced Studies (DIAS) with the support of PetroTrace and Tullow Oil. The Chapter wishes to acknowledge DIAS for hosting the event in its magnificent old building in the centre of historic Georgian Dublin. You can follow LC Ireland via LinkedIn to learn about upcoming events. LC Aberdeen welcomed Evgeny Landa at the prestigious Sir Duncan Rice Library at University of Aberdeen. The lecture here was perfectly timed for the start of a new academic year and there was a strong attendance from the new MSc and PhD students. The Student Chapter in Aberdeen was formed last year and is in the process of electing a new committee. The new student committee will have the full support of LC Aberdeen which has also restructured its committee and recruited some new members. This positions it well for the future. The EAGE Education Tours are due to return to Aberdeen on 1 November when Ian Jones is scheduled to present his one-day course on Velocity Imaging and Waveform Inversion. The Local Chapter is also working on its programme of events for next year that will include evening lectures, workshops, social activities and more collaborative events with PESGB, SPE and the EAGE Student Chapter.

IEA predicts big growth in petrochemicals market

Brazil sells all blocks in licensing round of prolific pre-salt blocks Big seismic surveys will take place offshore Brazil in the next few months after all four blocks on offer in the country’s 5th Production Sharing Round were sold. The winning consortiums are Shell/Chevron, ExxonMobil/Qatar Petroleum, BP/ Eco Petrol/CNOOC and Petrobras. The licensing round on 28 September offered 35-year production-sharing contracts in the Saturno, Tita, Pau-Brasil and Sudoeste de Tartaruga Verde pre-salt areas. Shell (50%, operator)/Chevron (50%) won the Saturno block in the Santos basin with a signing bonus of $780 million, offering 70.2% of profit. ExxonMobil (64%, operator) and Qatar Petroleum (34%) won the Tita block in the Santos basin with a signing bonus of $780 million, offering 23.5% of profit. BP (50%, operator), Eco Petrol (20%) and CNOOC (30%) won the Pau Brazil block in the Santos basin for a signing bonus of $1.25 billion, offering 63.8% of profit. Petrobras (100%) won the Sudoeste de Tartaruga Verde block in the Campos basin for a signing fee for $1.75 billion, offering 10% of profit. The four winners plan to invest some $250 million in planned investments during the exploration phase.

‘It was the first production-sharing round with more than one block on offer to have 100% of the areas acquired,’ said ANP’s director general, Décio Oddone. ‘With today’s goodwill profit, which averaged 170%, our expectation of raising royalties and taxes over the 35 years of the contracts rose from $45 billion to $60 million. But the most important thing is to look at the total of the production-sharing rounds since last year. The results of the 2nd to 5th rounds, considering the price of oil at $70 a barrel, will generate $300 billion in revenue for the Federal Government, states and municipalities, or about $10 billion per year.’ In the bids under the production-sharing regime, the winning companies are those who offer the Brazilian State, from a minimum percentage set in the tender protocol, the largest portion of oil and natural gas produced (i.e., the largest portion of profit oil).

ExxonMobil, Chevron and Occidental join Oil and Gas Climate Initiative

A meeting of the OGCI which invests in mitigating the risks of climate change.

A trio of US oil majors ExxonMobil, Chevron and Occidental have joined the Oil and Gas Climate Initiative (OGCI) signalling a step change in how they intend to respond to challenge of climate change and ‘energy transition’. The Oil and Gas Climate Initiative (OGCI), representing the world’s largest oil and gas producers working towards solutions to mitigate the risks of climate change, now has 13 members who produce some 30 per cent of the world’s oil and gas. The CEO-led organization focuses on developing practical solutions in areas including carbon capture and storage, methane emissions reductions and energy and transportation efficiency. As part of the initiative, ExxonMobil will expand its investment in research and development of longterm solutions to reduce greenhouse gas emissions. ‘It will take the collective efforts of many in the energy industry and society to develop scalable, affordable solutions that will be needed to address the risks of climate change,’ said Darren Woods, chairman and chief executive officer of ExxonMobil, who replaced Rex Tillerson at the start of 2017. ‘Our mission is to supply energy for modern life and improve living standards around the world while minimizing impacts on the environment. This dual challenge is one of the most important issues facing society and our company.’ All three companies are understood to have come under pressure from their shareholders to do more to combat global warming and have faced the threat of legal action from several US cities and states 24

because of their contribution to rising global temperatures. ExxonMobil said that it has already invested billions of dollars in researching and developing lower-emission solutions, including carbon capture and storage technology, next-generation biofuels, cogeneration and more efficient manufacturing processes. Earlier this year, ExxonMobil announced initiatives to lower greenhouse gas emissions associated with its operations by 2020, including reducing methane emissions by 15% and flaring by 25%. Since 2000, ExxonMobil has spent more than $9 billion to develop and deploy higher-efficiency and lower-emission energy solutions across its operations. Meanwhile, the OGC has agreed a target to reduce collective methane emissions from their upstream operations. The 13 companies have set a goal to reduce by 2025 their aggregated average methane intensity from upstream oil and gas operations to below 0.25% to cut collective methane emissions by 350,000 tonnes annually. BP chief executive and OGCI chair, Bob Dudley, said: ‘Our ambition is to go beyond this target, down to 0.2% to achieve as much as a one-third reduction in the same timeframe. This is exactly the kind of progress we hoped for when we established the OGCI in 2014.’ At the same meeting, the group also announced investments in methane emissions detection and mitigation technologies through its Climate Investments arm. ‘These investments in methane leak detection and prevention are the types of

practical innovations that can get implemented quickly and will allow our companies to achieve an immediate and meaningful win for climate action,’ said Pratima Rangarajan, CEO of Climate Investments. OGCI Climate Investments announced that it is partnering with China National Petroleum Corporation (CNPC) to create an investment fund focused on China. A minimum of $100 million dollars is being invested to focus on the development, demonstration, and rapid scale-up of technologies and business solutions that have the potential to reduce greenhouse gases. OGCI was established after the 2014 World Economic Forum and formally launched at the United Nations Climate Summit the same year. Members include BP, Chevron, CNPC, Eni, Equinor, ExxonMobil, Occidental Petroleum, Pemex, Petrobras, Repsol, Royal Dutch Shell, Saudi Aramco and Total. Each member puts $100 million into an investment fund to develop technologies to reduce carbon emissions. Indian oil and gas company Reliance has confirmed that it left the OGCI earlier this year. Reliance had joined the initiative in 2016. The company produces 1.2 million barrels of oil a day, about 1% of global oil production.

UK offshore oil sector at ‘crossroads’ says report Industry body Oil and Gas UK has warned of problems ahead for the UK offshore oil sector because of record low drilling activity. Oil & Gas UK chief executive Deirdre Michie said: ‘Despite the improvements seen in recent years, we find ourselves at a crossroads. Record low drilling activity, coupled with the supply chain squeeze, threaten industry’s ability to effectively service an increase in activity and maximize economic recovery. The body’s Economic Report 2018 notes that four exploration wells were spudded in the first eight months of the year – and even with more wells to come, total exploration activity this year is expected to be the lowest since 1965. Meanwhile, the capacity of the supply

chain has been reduced in recent years, as revenues and margins continue to be squeezed. By 2021 there could be capacity constraints emerging across the supply chain as a result of the reductions in recent years and an expected increase in new development activity at home and abroad. The constraints are expected to be felt most across drilling and wells services and within engineering and subsea sectors. However, Oil & Gas UK also highlighted findings which highlighted reduced costs, competitive fiscal terms, improved operational performance and more stable oil and gas prices. The report shows that operating costs have halved and are now being sustained

at around $15/boe. Production is on track to be 20% higher than in 2014 and big discoveries are still being made such as Total’s Glendronach find West of Shetland. More major new projects have been sanctioned so far this year than the last two years combined. ‘The UK Continental Shelf is a more attractive investment proposition – our challenge now is to take advantage of this,’ added Michie. ‘We have to drive an increase in activity while continuing to find and implement even more efficient ways of working which support the health of supply chain companies whilst also keeping costs under control. ‘It shows that investment conditions remain key to the long-term future of the North Sea industry.’

CGG starts 3D survey offshore UK

US proposes big GoM lease sale in Spring 2019

CGG has started acquisition of a high-density, rich-azimuth, towed-streamer multi-client survey in the UK West Shetland Basin. The 3600 km2 survey has been designed in collaboration with international oil companies. It focuses on delivering high-resolution seismic data in a prospective but underexplored area north-west of the Shetland Islands over the northern part of the Rona Ridge. A fast-track PreSDM data set will be available in Q1 2019. The innovative acquisition geometry is designed to image multiple targets from shallow Tertiary and Cretaceous plays to complex fractured Devono-Carboniferous reservoirs by undershooting the volcanic intrusions and shallow unconformities present in the area. Two vessels, the Oceanic Vega and the Geo Caribbean, are being deployed. Each vessel operates triple sources using simultaneous source technology. The data will be processed in depth using CGG’s broadband imaging technology, including advanced de-blending

Cuadrilla gets permission for second shale well in UK Cuadrilla was due to start hydraulically fracturing the shale rock around the first of its two horizontal shale gas exploration wells in the north of the UK in mid-October. The hydraulic fracturing process at Preston New Road in Lancashire will take approx. three months to complete for both exploration wells. The fracturing of the shale rock, more than 2-km deep, will release the natural gas in the shale to flow up the wellbore to the surface. The flow rate of the natural gas will be tested over approx. six months with initial results expected in the first quarter of next year. Francis Egan, CEO of Cuadrilla, said: ‘The start of hydraulic fracturing is the final milestone in the journey to assessing the flow rates of natural gas from our Lancashire shale exploration wells. On completion of hydraulic fracturing and commencement of gas flow, we expect to have, in the first quarter of next year, an initial assessment of how much natural gas is likely to be recoverable from these first Lancashire shale wells. This will allow us to make an assessment of the commercial viability and future of this exploration site. Lancashire has benefited to date from more

than £11 million of investment generated by our exploration operations. This investment will grow very significantly if we move from exploration into commercial production.’ Cuadrilla had received hydraulic fracturing consent from the UK Department for Business, Energy & Industrial Strategy (BEIS) for its second horizontal shale exploration well at its Preston New Road site in September. Planning and permits required for both wells are already secured. The first horizontal shale well was completed by Cuadrilla in April 2018 through the Lower Bowland shale rock at approx. 2300 m below surface and extends laterally for some 800 m. The second horizontal shale gas well was completed in July 2018 and was drilled through the Upper Bowland shale at an approximate depth of 2100 m below the surface, extending laterally for some 750 m through the shale. These are the first two horizontal shale exploration wells to be drilled onshore in the UK. After hydraulic fracturing of these first two horizontal wells Cuadrilla will run an initial flow test of the gas produced from both wells for approx. six months.

Meanwhile, Third Energy, one of the companies at the frontline of the UK’s fracking drive, has been hit by the departure of two of its directors owing to delays over its flagship project in North Yorkshire in the North of England. The company had looked likely to be the first shale explorer to frack in the UK for years, but its plans for the KM8 well near the village of Kirby Misperton have been pushed back by government checks over its financial health and it is understood that no fracking will take place this year. The resignation of Keith Cochrane and Jitesh Gadhia, which emerged in company filings, is understood to be connected to delays in granting consent for the well. ‘As the hydraulic fracturing programme and further development is currently delayed, with resulting low levels of activity, the company has accepted the directors’ resignations,’ a spokesperson said. The British government is also facing a revolt from 20 Conservative MPs who are ready to vote against government proposals to fast-track shale projects through the UK planning system.

Oil price set for $100 a barrel by end of year Oil trading houses are predicting the return of $100 crude oil for the first time since 2014 as the market braces itself for the loss of Iranian supplies because of US sanctions. Mercuria Energy Group Ltd co-founder Daniel Jaeggi said prices may spike to more than $100 a barrel in the fourth quarter because the market does not have much capacity left to replace more than 2 million barrels a day of Iranian exports that could be lost to US sanctions. Trafigura Group co-head of oil trading Ben Luckock sees $90 oil by Christmas and $100 in early 2019.

‘The market does not have the supply response for a potential disappearance of 2 million barrels a day in the fourth quarter,’ Jaeggi said. ‘In my view, that makes it conceivable to see a price spike north of $100 a barrel.’ Citigroup Inc. also flagged the possibility of triple-digit crude prices in a Sept. 24 research note. ‘While Citi is pricing in Brent (ICE) crude at around $80 for the quarter ahead, balances are precarious and the lack of spare capacity could see crude pricing well above $90 or even $100 should all of the potential risk in the market materialize,’ it said in a statement.

The talk of $100 crude comes just hours after OPEC and its allies rebuffed pressure from US President Donald Trump to immediately boost production to lower oil prices. In addition to US sanctions cutting Iranian supply, the world is also dealing with a decline in Venezuelan oil production owing to an economic crisis in the Latin American nation, according to Trafigura’s Luckock. The biggest source of new global supply, US shale, is also experiencing production problems owing to pipeline bottlenecks and workforce issue, he added.

Shell commits to cutting methane emissions to below 0.2%

Shell has announced a target to maintain methane emissions intensity below 0.2% by 2025. This target covers all oil and gas assets for which Shell is the operator. ‘This methane target complements Shell’s ambition to cut the net carbon footprint of our energy products by around half by 2050, which we announced in November 2017,’ said Maarten Wetselaar, Shell’s integrated gas and new energies director. 28

To maintain this methane target, Shell is implementing programmes, including using infrared cameras to scan for methane emissions, deploying advanced technology to repair leaks, and replacing high-bleed pneumatically-operated controllers with low emission alternatives. The company said it recognised that there remains uncertainty with measuring methane emissions. ‘This is an industry-wide issue and we need to fix this fast,’ Wetselaar added. ‘We must get a much more accurate understanding of how much we are emitting.’ The target for methane – which has a higher impact on global warming than carbon dioxide when released into the atmosphere – will be measured against a baseline Shell leak rate, which is currently estimated to range from 0.01% to 0.8% across the company’s oil and gas assets. ‘Methane is a potent greenhouse gas, but it has a relatively short lifetime in the atmosphere.

These guiding principles have now been adopted by 16 companies. Shell has been an active member of the World Bank-sponsored Global Gas Flaring Reduction partnership since 2002. As part of this, the World Bank has developed the Zero Routine Flaring by 2030 initiative, which Shell signed in 2015. This encourages governments, companies and development organizations to work together to end flaring.

TGS found guilty of tax violations by Oslo court An Oslo district court has proclaimed a guilty verdict against TGS of aiding and abetting violations of Norway’s Tax Assessment Act related to a contract for the purchase of seismic data and services in 2009 by Skeie Energy (now known as E&P Holding). TGS has been ordered to pay a fine of $11 million. The company said it ‘categorically disagrees’ with the guilty verdict and will appeal. In May 2014 Økokrim, the Norwegian National Authority for Investigation and Prosecution of Economic and Environmental Crime, presented a criminal charge against TGS for violation of the Norwegian Tax Assessment Act and the Norwegian Securities Trading Act. The charge claimed that TGS contributed to an unwarranted tax refund related to the licensing of TGS multi-cli-

ent seismic data in the North Sea and Barents Sea to Skeie Energy. In addition, Skeie Energy prefunded a large 3D survey in the Hoop area of the Barents Sea. These surveys have since been licensed to multiple customers. The payment for the transaction was made through a combination of cash payment and two loans of a total net value of $29.4 million, which matured at year end 2010. Owing to Skeie Energy’s failed attempt to raise new capital, the loans were not repaid according to the agreement at the maturity date. TGS actively tried to collect its receivables from Skeie Energy in the period since default and recognized an impairment of $19.9 million in 2011. TGS, as a seismic data provider, does not participate in Norway’s petroleum tax refund system and received no tax benefits from the sale of seismic data

The company said that it views the sale of seismic data to Skeie Energy as a legitimate transaction between two independent companies, involving a sale of high-quality seismic data at market prices. TGS said that it was also advised by third party legal and financial experts in relation to the transaction. Økokrim had earlier dismissed the charges against TGS of market manipulation for presenting incorrect financial information to the market in violation of the Securities Trading Act. Økokrim said there was insufficient evidence to suggest market manipulation.

IAGC condemns New Zealand ban on exploration The International Association of Geophysical Contractors (IAGC) has condemned New Zealand’s introduction of legislation to ban new offshore exploration as a betrayal of the companies that have invested some $70 million in seismic surveys there in the past five years. New Zealand’s prime minister Jacinda Arden has said that the proposed amendment to the Crown Minerals Act will not affect the country’s existing 22 oil and gas permits that still have ‘decades to run’. However, the IAGC - which represents 110 companies from the geophysical and exploration sector - called the country’s introduction of a bill banning new offshore exploration a clear demonstration of putting environmental politics

ahead of the sentiments of the people and economy of New Zealand. ‘The International Association of Geophysical Contractors (IAGC) is disappointed that the changes contained within the proposed bill will not allow our members nor New Zealanders to fully realize the value of the more than $70 million investment that the seismic industry has made in offshore New Zealand since 2013. The IAGC’s members invested in New Zealand with an expectation that its laws would be reliable and regulatory regime stable. ‘Contrary to the prime minister’s assertion that with these proposed changes, “All existing permits are protected and will be allowed to run their full course – meaning we have many years’ worth of gas supply remaining and explo-

ration will continue,” this is not the case. The holders of existing petroleum prospecting permits will not be able to realize returns on their investments. ‘Employment rates in New Zealand will decline, oil and gas supplies will be affected and there will be a consequential increase in oil, gas and electricity prices. We strongly condemn this action by the New Zealand Government and oppose this bill which undermines investment made in the country. ‘Finally, the government continues to move forward making decisions in a vacuum and without any consultation or notification to the industry. The IAGC urges the New Zealand Government to reconsider this short-sighted decision with engagement from the affected industries.’

IEA predicts big growth in petrochemicals market Petrochemicals are becoming the largest drivers of global oil demand, according to a study by the International Energy Agency (IEA). The study highlights that petrochemicals are set to account for more than a third of the growth in world oil demand to 2030, and nearly half the growth to 2050. Demand for plastics (described in the report as the most familiar petrochemical product) has outpaced all other bulk materials (such as steel, aluminium or cement), nearly doubling since 2000, the report states. The report also says that advanced economies currently use up to 20 times as much plastic and up to ten times as much fertilizer than developing economies on a per capita basis, ‘underscoring the huge potential for growth worldwide’. Against a backdrop of slower gasoline demand growth, robust growth prospects for chemical products, and attractive margins, oil companies are further strengthening their links with

exert on future energy trends. In fact, our analysis shows they will have a greater influence on the future of oil demand than cars, trucks and aviation,’ he added. Petrochemicals are components derived from oil and gas that are used in products such as plastics, fertilizers, packaging, clothing, digital devices, medical equipment, detergents and tires.

The NPD has granted Equinor a drilling permit for wildcat well 6407/111 in production licence PL 751. The well will be drilled about 17 km southeast of the Njord field. The NPD has granted Faroe Petroleum Norge consent for a wildcat well in production licence PL 825. The well will be drilled 7 km north of the Oseberg field. Norway has also given Faroe Petroleum consent to drill the Brasse East well in the North Sea.

Time has come for ‘Gas to Wire’ in the UK An innovative partnership between gas platforms and windfarms could lead to more power generated, according to a report from the UK Oil and Gas Authority (OGA). The concept of gas-to-wire (GTW) involves using the gas produced from gas fields to be generated into electricity offshore and then transmitted to shore via spare capacity with subsea cables used for windfarms. Owing to the intermittence of wind, annual use of the associated power infrastructure is typically 40%. This spare capacity presents an alternative route for electricity generated offshore from currently producing gas fields or even from undeveloped discoveries and stranded gas resources.

By installing offshore power generation facilities, operators could export electricity via established windfarm infrastructure instead of exporting gas to shore by pipeline. As a relatively flexible and fast-responding form of power generation, it could play a useful role in balancing the electricity grid as supply and demand fluctuates. The report Gas To Wire: UK SNS and EIS looks at the technical considerations and potential benefits from GTW in areas such as the Southern North Sea and the East Irish Sea. Both are unique in featuring established offshore gas-producing facilities and infrastructure alongside large existing and planned offshore windfarms. In addition to generating additional electricity offshore, other benefits from

gas and renewables collaboration include the potential to reduce operating costs by pooling logistics and establishing guidance for effective co-existence within the same geographic area. The OGA is working with the East of England Energy Group (EEEGR) a cross-industry working group which aims to promote gas and renewables synergies. Simon Gray, CEO of EEEGR, said: ‘When we first looked at this opportunity, the barriers to market seemed just too difficult to overcome. However, the legislative difficulties now seem to be surmountable, the technology achievable and the market more willing to consider this as a real opportunity.

CGG signs multi-year agreement for UK ground hazards data High-precision ground stability measurements from CGG’s recently released MotionMap UK database will be used to enhance the ground risk reports of Terrafirma Search, the UK adviser on ground hazards. MotionMap UK data is generated using satellite InSAR data processing to give geologists, engineers and surveyors insight into the location, extent and evolution of ground stability hazards. After signing a multi-year agreement with CGG, Terrafirma becomes one of the first UK companies to include the latest-generation MotionMap UK data, which reveals millimetre-scale changes in ground and building heights in its suite of geological, geotechnical and environmental services. The MotionMap UK data will enhance the insight, risk ratings and professional recommendations of Terrafirma’s property and land reports to identify, assess, manage and resolve ground hazards. Adam Thomas, InSAR manager at CGG’s NPA Satellite Mapping group, said: ‘This announcement is the culmination of

considerable technical and commercial collaboration between CGG and Terrafirma over the last two years to provide clear and actionable information on ground stability. We worked together to refine and develop a new MotionMap UK database that works seamlessly with Terrafirma’s risk analysis and ‘rules engine’ so that the data can be fully utilized in their suite of property and land reports.’ Tom Backhouse, managing director of Terrafirma Search, said: ‘Terrafirma has been working for many years to move past expert hypothesis into evidence-based risk modelling. Our new Ground Report, released to professionals in September 2018, is for the first time utilizing ‘real-world’ evidence, including Terrafirma’s SinkholeALERT, a database of more than 120,000 investigated subsidence claims, and CGG’s new MotionMap UK database. This evidence is integrated into the analysis of ground conditions, including past mining activity and natural ground perils.’
