EAGE NEWS

Fibre optic sensing is topic for Kuala Lumpur workshop The demand in novel technologies for energy industry is probably one of the highest in Asia-Pacific with the potential of fibre optic solutions high on the agenda.

This makes sense as it is the most populous part of the world and consumes half of the energy produced globally.

This is the reasoning behind EAGE’s 2nd Workshop on Fibre Optic Sensing for Energy Applications in Kuala-Lumpur, Malaysia, on 5-7 December 2022, chaired

by Prof Roman Pevzner of Curtin University and co chaired Hafizal Mad Zahir of PETRONAS. Distributed fibre optic sensing is an already established yet still novel and rapidly developing technology. It offers a high disruptive potential for nearly the entire energy industry itself undergoing rapid transformation.. Tiny, but robust and versatile optical fibres can provide vital information about hydrocarbon reservoir production, energy transport through

wires or pipelines or subsurface storage of various fluids, such as natural gas, CO2 or hydrogen.

The ability to monitor the entire process of energy production, distribution and waste management through a multiplicity of physical parameters derived from distributed optical sensors plays a critical role in process optimisation and cost reduction, both much needed by the industry.

The workshop will cover a range of topics, from the relevant advances in fibre optic sensing and data analysis to showcasing of DAS, DSS and DTS applications in subsurface imaging and monitoring. It will cater for a broad range of geoscientists, geophysicists, reservoir engineers interested in the technology as well as for experts in fibre optic sensing looking to expand into the energy industry.

The workshop takes place in Kuala Lumpur, with online support for remote presenters. Apart from presentations from

KL at night.

PETRONAS, Silixa, Aramco, Sercel, Schlumberger, Halliburton, Curtin University, CSIRO and many others, we will also hold a round table discussion on the uptake of fibre optic sensing versus using conventional tools and several live demos provided by some of the leading hardware and software vendors. For further information, see EAGE website.

ADDITIONS THIS MONTH The Near Surface Geoscience Conference and Exhibition 2022 will take place on 18-22 September in Belgrade, Serbia hosting three conferences as parallel programmes: • 28th European Meeting of Environmental and Engineering Geophysics • 4th Conference on Geophysics for Mineral Exploration and Mining • 3 rd Conference on Airborne, Drone and Robotic Geophysics Extended abstracts for all three conferences will be available on EarthDoc two weeks before the event.

Abstracts from the 4th HGS/EAGE Conference on Latin America (14-16 September, Cartagena, Colombia), from the 6th EAGE High Performance Computing Workshop (19-21 September, Milan, Italy) and from the 6th International Conference on Fault and Top Seals (26-28 September, Vienna, Austria) will be accessible at the beginning of September.

Towards the end of September, EarthDoc will start hosting abstracts from the 6th EAGE Eastern Africa Petroleum Geoscience Forum (10-12 October, Cape Town, South Africa) and from the 1st EAGE West Africa E&P Workshop (12-14 October, Cape Town, South Africa).

Lastly, a new issue of Geophysical Prospecting will become available on EarthDoc in September.

German students experience some action in Freiberg In May 2022 over 70 geophysics students from all over Germany came to Freiberg (Saxony) to meet local students for the annual geophysical action programme (GAP). It was a weekend filled with excursions and conversations with like-minded people along with presentations by companies related to geophysics.

After an evening ice-breaking including various competitions between students, the Friday morning saw the start of the cultural, sporting and geophysical excursions started. The students had the choice between a visit to the Alte Hoffnung Erbstolln mine, a city trip to Dresden or Freiberg or a visit to the Freiberg University seismological observation site in Berggießhübel.

After visiting the old mining site near Mittweida, the group made a trip to Kriebstein Castle and participated in a medieval festival. The Dresden tour included famous museums and the historic city centre and passed the Frauen-

Netherlands Chapter talk covers forecasting natural and induced seismicity

A moment during the technical lecture by Dr Ylona van Dinther.

Dong Zhang (EAGE Local Chapter Netherlands) writes: With the pandemic fading away, EAGE Local Chapter Netherlands held a live event at Utrecht University on 17 May focusing on understanding and forecasting natural and induced seismicity. Dr Ylona van Dinther from the Department of Earth Sciences at Utrecht University, was the speaker. She is credited with the

pioneering of the bridging of from tectonic time scales (millions of years) down to earthquake ones (milliseconds to years) in numerical models.

Dr van Dinther began her talk with an introduction to earthquake sequences, combining the knowledge from observations and physics-based models.

More specifically, her group combined earthquake or tectonics numerical or analytical models with geological and geophysical observations in various ways ranging from using predicting new, verifiable observations; to loose or tight data constraints; to integrating them tightly in a statistically meaningful way. It turned out that the current and future outcomes are important to improve natural and induced earthquake and tsunami hazard assessment.

More cool things were also mentioned during the talk, such as applying ensemble data assimilation, a statistical

method adopted from weather forecasting to estimate and forecast the state of stress and slip on the fault, comparing natural and induced seismicity, laboratory experiments on Groningen rocks, etc. The audience onsite brought forward many insightful questions. Some were curious about whether AI could help with this problem or not.

During the session Dr van Dinther also shared her work and life experiences as a woman in geosciences.

academia to industry realize the Energy Transition; and 4) engaging the student community and the faculty to collect, disseminate and exchange geotechnical knowledge in the exploration of energy resources.

This focus led to a new event called Explorati where the geosciences could be explored as a means for achieving the Energy Transition.

Other events that have been organised include Petrohunt 2022, a fun case study competition designed for increasing the knowledge in the broad field of geoscience as applicable to the oil and gas industry. It challenged multi-disciplinary teams to take a shot at appraising a subsurface resource thereby working with a real dataset. Teams registered with a captain and a maximum of three members per team. The teams had to characterise a given subsurface hydrocarbon resource using an open-source dataset. Judging was based on sustainable carbon management along with an appraisal of the proposed plans. A total of 33 students participated in this exciting competition The winners received Rs 3000 and the runners-up Rs2000 - and Rs 1000 along with sponsored EAGE student chapter membership.

Treasure Trove 2022 was a fun treasure-hunt game with geoscientific clues which led from one destination to another until reaching the end. The biggest challenge for the students in this event was the race against time. The winners and the runners-up received sponsored EAGE student chapter membership

Bogota students hold a climate and ocean GeoQuiz EAGE Student Chapter National University of Colombia (UNAL Bogota) recently held a Climate and Ocean Geoquiz competition that tested geology students’ knowledge on earth, atmospheric and ocean sciences.

There were three virtual preliminary rounds. The highest four scores were selected for the in-person final challenge on 1 July. This last stage was focused on climate change and its understanding through geosciences. The winner, Jose Maria Cantillo de La Hoz (8 th semester student, Bachelor in Geology) received a financial award prize and a fossil sample. EAGE staff participated in the closing session presenting the benefits of being part of our student community.

The UNAL Bogota Student Chapter, active since 2020, is divided into three

seedbed groups: ‘Geophysics and Seismology’, ‘Volcanology and Geothermal’, and ‘Paleoclimatology and Glaciology’.

This last group was responsible for the recent Geoquiz. The first edition focused on mineralogy took place in October last year.

The Chapter is one of the most active in Latin America and this year three of its members won the second place at the EAGE Online GeoQuiz. Among their upcoming activities, it is planning a series of ‘Python in Geosciences’ courses ending with a GeoHackathon in October.

We send our congratulations to the winners and to the National University of Colombia Chapter, currently led by Wendy Arias (president) and Juan Manuel Jimenez (vice-president), for such great initiatives and keeping the student GeoQuiz tradition alive.

Cape Town workshops explore the next steps in exploration journey offshore East and West Africa Why you should consider joining EAGE’s two workshops taking place in Cape Town, South Africa from the 10-14 October 2022 focusing on the future of petroleum geoscience in the East Africa region and emerging exploration experiences and challenges in West Africa?

The organisers explain.

Cape Town ocean view.

World-class offshore and onshore energy resources await discovery and development across Africa. With the recent pandemic and climate change, now is the time to pool our experience and look forward to planning strategic change.

Africa has the right to a just transition. Ideally we need to accelerate our understanding to address new challenges and find ways to complete the carbon-cycle, to create sustainable environmentally responsible loops. We plan a sixth technical forum to discuss ways to ensure continuation with certainty.

We will refer to lessons learnt from the fifth forum and the recent EAGE Annual Conference, whilst considering recent events affecting the future of petroleum geoscience in the Eastern Africa energy mix.

We have to plan integrated projects that develop the local economy while also generating export revenues.

The world requires energy. We urgently need to plan future development considering the new challenge to reduce carbon dioxide and methane release to the atmosphere. With discoveries made

as far back as the early 2000s, plus relative political and economic stability in recent years, the exploration and production possibilities in West Africa are promising.

Regional workshops such as this one aim to bring concrete actions into play and encourage working across boundaries that we may not have explored in the past. We plan to have dedicated sessions providing a good forum to openly share thoughts on the most relevant topics. The Eastern African forum will share planning with EAGE West Africa to bring together a week of in-person events..

Main topics to be covered include Subsurface, Above Ground, Petroleum Systems and Play Understanding, Technology advances, Commercial/Above Ground, Energy Transition. The programme will include panel discussions, round table and working/small groups that will focus on knowledge sharing, collaboration and state of the industry.

Parallel focus sessions will be implemented into the programme including a poster area for service companies and research projects, so that the entire FIRST

audience remains engaged around their specific challenges.

You can now review the technical programme for the sixth edition on the event website and read about the keynote speakers who will rely on their years of experience and insights to the changing climate within the industry.

PERSONAL RECORD INTERVIEW

Ann Robertson-Tait

Personal Record Interview A relentless force for geothermal good Ann Robertson-Tait is president of GeothermEx (a Schlumberger company) and global chair of Women in Geothermal (WING).

For 37 years she has been a passionate advocate of geothermal power in the international energy community and has personally been involved in at least 70 projects covering virtually every significant geothermal energy source in the world.

Your early life I grew up lucky in New York. Three of four of my grandparents were university educated, the fourth was an opera singer. We were a family of hi-fi nuts into all musical genres: Beethoven, Basie, Beatles, Bennett, Bossa Nova, Strauss (Johann and Richard), showtunes, and lots of Sinatra. I started school at Montego Bay Preparatory School in Jamaica where my father was working for a time, then it was back to Long Island, NY for the rest.

I played clarinet in the band, sang in the choir and at school shows. These days my alter ego is a singer in a local dance band doing gigs here in California.

The learning years I first attended community college to get my bearings, then a BS in geology, Florida Atlantic University, including a hydrogeology internship at a local water management district. I fancied an energy career, but not oil and gas, especially if it meant a life spent in hot and humid southern US states! My senior research paper was on geothermal energy, and it really caught my attention. That’s how I ended up with a Fulbright Scholarship doing a geology MSc at Auckland University in New Zealand, learning my craft through coursework and a thesis on causes of subsidence at the famous Wairakei field. Bonus: I met my spouse and soulmate — we remain together.

Then what?

Although warned that the work was interesting, but the office anything but fancy, I joined GeothermEx in 1985 and immediately got stuck into work on projects

in Japan, Italy, California and Nevada.

To start with I didn’t know enough about non-geoscientific aspects, so pestered reservoir and drilling engineers relentlessly, slinking into power plants whenever possible.

(EGS) and ‘geothermal+’ hybrid systems that maximize clean energy production.

We must advocate to governments and industry, and demand R&D support levels common to all other energy technologies except geothermal.

Projects that inspired The best ones followed the GeothermEx mantra: listen, evaluate issues, think/ discuss, identify alternatives, provide practical solutions – make geothermal happen. For example, I am proud of convincing a large, well-known bank to issue the first-ever non-recourse loan for a geothermal project; undertaking the first full-field simulation of the world’s largest geothermal field (The Geysers, now in its 53rd year of production). Another highlight was advising a major geothermal operator that exploration drilling results did not justify its development plan. Honesty and frankness (my business mantra) became a driver for an improved plan. Work continues today for this operator.

Your typical week Monday through Wednesday is always chock-a-block with client and internal meetings; reviews of company reports, proposals, confidentiality agreements, contracts, etc. interfacing with account managers and business lines needing geothermal support within Schlumberger; and knowledge transfer to company staff.

The remainder of the week is given to thinking, planning and advocacy, often spending part of the weekend to catch up.

How to accelerate geothermal adoption?

We need to recognise that geothermal is not a poor cousin of other renewables and acknowledge the grid-stabilizing value of clean baseload geothermal power.

Spreading the word that geothermal is everywhere in one form or another is important — shallow heat exchange for space heating and cooling; direct use of hot fluids for district heating/cooling, spas and many industrial applications; recovery of critical minerals; new technologies such as stimulating hot, tight rock FIRST

BREAK

Importance of WING? We are proud to be the largest single geothermal organisation in the world, dedicated to helping women recognise their own value/uniqueness in a male-dominated industry, also knowing that WINGmen (and gender equality generally) are crucial to our mission. We encourage women to be bold, to ‘go for the no’, and to keep asking – you may get what you want – and to call out bad behaviour in a reasonable way using open questions (not accusations), a useful skill in many situations.

Legacy hope On retirement (not imminent!) I hope to have imbued staff with pride in the 50 years of GeothermEx history advancing thousands of geothermal projects, providing accurate and useful advice.

TGS buys wind energy start-up

Seismic acquisition market recovery gathers pace Companies that acquire and sell seismic data have reported healthy second quarter net profits in a further sign that their long-depressed market is in sustained recovery.

TGS has reported second quarter net profit of $25 million on revenues of $230 million compared with a net loss of $15 million on revenues of $72 million in Q2 2021.

PGS, which has all six of its seismic acquisition vessels back in operation, has reported second quarter net income of $19 million on revenues of $273.6 million (its second best quarterly figures since 2014), compared to a net loss of $26 million on revenues of $185.9 million in Q2 2021.

CGG, which has repositioned itself as a broader data company, has reported second quarter net income of $16 million on revenues of $228 million compared to a net loss of $51 million on revenues of $172 million in Q2 2021.

The uptick in sales of seismic data has coincided with another big increase in quarterly profits reported by the international oil and gas majors, who are increasing investment in frontier exploration and are reviving shelved projects that have become viable as a result of the embargo on Russian oil and gas.

Kristian Johansen, CEO of TGS, said: ‘International oil companies have revived

their interest in frontier exploration, driven by high energy prices, recovery of licensing round activity, significant exploration success and renewed focus on energy security. This, in combination with continued focus on infrastructure-led exploration (ILX), has driven a significant improvement of the global market for multi-client seismic data over the past nine months.

‘As the energy transition progresses, global energy markets are growing increasingly fragmented, volatile and complex. This means that there is a growing need for data, insights and software to support decisions and manage assets,’ added Johansen, who had an early vote of confidence in the company’s recent acquisition of Magseis Fairfield as the company demonstrated the growing market for ocean bottom node seismic acquisition, posting second quarter revenue of $103 million and a tenfold increase in gross profit (see page 22 for full report).

Rune Olav Pedersen, president and chief executive officer of PGS, said: ‘PGS expects global energy consumption to continue to increase longer term with oil and gas remaining an important part of the energy mix, as the global energy transition evolves. Offshore reserves will be vital for future energy supply and support demand for marine seismic services. With high oil and gas prices, the seismic market FIRST

has entered a recovery phase, and the positive trend is expected to continue due to increasing investments among energy companies. Russia’s invasion of Ukraine has significantly increased the general focus on energy security and, combined with several years of low investment in new oil and gas supplies, has further increased oil and gas prices and investment pressures on energy companies. The seismic acquisition market is likely to benefit from a significant reduction of operated vessel supply over several years’ (see page 24 for full report).

Sophie Zurquiyah, CGG CEO, said: ‘Market trends, driven by continued underinvestment in exploration and production and intensified by elevated energy security concerns, continue to support our view of a multi-year upcycle with increased spending from all clients, as they progressively refocus on exploration to meet future energy demand (see page 26 for full report).

UK releases more seismic data to aid energy transition projects

Offshore wind farm in the North Sea.

The search for carbon storage sites, wind farm locations and potential hydrocarbon fields has received a significant boost as more than 132 terabytes of seismic data has been uploaded on to the National Data Repository (NDR).

The data can be used to support the UK’s first ever carbon storage licensing round, which was launched in June this year and, as the Energy Transition gathers pace, increasing numbers of NDR users are using the archive of information to aid exploration efforts.

A total of 29 data sets dating from 1988 to 2015 have been transferred from tape storage to the cloud, where they can be easily accessed by companies and researchers.

The data sets, the largest of which is 72 terabytes, are mostly located in

the Central North Sea and Southern North Sea and cover areas that are considered to have significant potential for carbon storage. The data can also be used for traditional petroleum exploration and for other uses such as positioning offshore wind installations.

The latest upload has taken seismic field data that has previously been reported to the NSTA. Working with Moveout Data Seismic Services, the data has been made ‘processing ready’, which assists users by completing the first step of reprocessing work for them.

As part of the project, around 200 tapes have been transferred from a controlled storage site into the NDR cloud, adding to the 26 similar data sets which have already been made available on the site in the last year.

Prior to the transfer, these multi-terabyte data sets were less accessible to users. Now fully released and ready to be processed, the data is listed in the NDR where it can be ordered for delivery.

Originally launched in 2019 with more than 130 terabytes of information – one of the largest ever single open releases of data – the NDR was refreshed to improve functionality for users last year.

PGS wins 3D survey offshore Indonesia

Ramform Sovereign will mobilise mid-October.

PGS has won a big 3D exploration acquisition contract offshore Indonesia from a major energy company. The company has also won a big 4D acquisition contract offshore Australia from an international energy company.

Vessel Ramform Sovereign will mobilize for the 3D exploration contract in Indonesia in mid-October and acquisition is expected to complete in mid-December.

The vessel will continue to Australia and mobilize for the 4D contract at the end of the year and complete acquisition towards the end of February 2023.

‘These two contracts constitute an acquisition campaign of close to five months. The seismic acquisition market in Asia-Pacific has been slower than in the Atlantic basins, so it is encouraging to experience increasing demand in the region, and we have good leads for additional work beyond the campaign we have already secured,’ said PGS president and CEO Rune Olav Pedersen.

Westwood research points to 13 big discoveries this year Thirty-eight high-impact exploration wells were drilled in the first half of 2022, compared with 39 wells completed in 2021, according to research by Westwood.

The wells resulted in 13 potentially commercial discoveries at a 34% commercial success rate, delivering ~6bnboe of discovered resource.

Eight of the wells tested frontier plays, with significant basin-opening discoveries at Venus and Graff in the Orange Basin offshore Namibia. Venus is the largest discovery in 2022 so far, with multi-bnboe potential in a Lower Cretaceous Aptian-Albian basin floor fan. There were, however, key frontier failures at Mlima in the Lamu Basin offshore Kenya and at Ulcinj offshore Montenegro.

Eighteen wells tested emerging plays in 1H 2022 resulting in nine commercial discoveries and a 50% commercial success rate. Eight wells were completed in the Upper Cretaceous play offshore Suriname-Guyana delivering six successes.

The other emerging play discoveries were in the Levantine (Athena), Perth (S Erregulla) and Orange (La Rona) basins. Key emerging play failures include Cutthroat in the Sergipe-Alagoas Basin, which tried to extend the Barra Upper Cretaceous

play, as well as Apus in the Roebuck Basin offshore Australia, which was unsuccessful in extending the Dorado play.

High impact exploration in maturing/ mature plays disappointed, with only one potentially commercial discovery from 12 wells drilled, at Huron in the US Gulf of Mexico. There were multiple failures attempting to extend the pre-salt play in Brazil, as well as further disappointments in the SWAP licence in the shallow waters of Azerbaijan.

High-impact drilling activity will pick up in the second half of the year, with between 80 and 90 high-impact wells expected to have been drilled by the end of 2022, the highest number since 2019 when 98 high impact wells were completed.

South America will continue to be an exploration hot spot with more wells planned for the Suriname-Guyana basin and offshore Brazil. There will be a return to high-impact exploration in Africa in 2022, with key wells planned in South Africa, Mozambique and Zimbabwe after the successes in Namibia earlier in the year. Whilst activity levels in Asia-Pacific and NW Europe are relatively stable, there will be a return to high-impact exploration in the deepwater of the Eastern Mediterra-

Searcher launches East Coast India 2D reprocessing project Searcher Seismic has launched a 2D reprocessing project for an area off the east coast of India.

Searcher’s Phase 1 reprocessing of 10,000 km multi-vintage 2D seismic data, has started in collaboration with Shearwater GeoServices. The broadband processing flow is designed to focus on preserving amplitudes, increasing signal bandwidth and AVA/AVO-friendly data improvements.

Using the latest 2D denoise and demultiple algorithms, the new data has removed artefacts and significantly improves signal-to-noise of the key prospective intervals which, when used on a regional scale, enables high-grade source kitchens and better constrained sedimentology of reservoir units, said Searcher.

East Coast India has proven its potential with exploration successes from the Ganges Delta to Krishna-Godavari Basin in both shallow and ultra-deep waters, said Searcher. ‘The clear logic of dis26

TGS buys stake in wind energy software start-up

The deal will help TGS to become more involved in wind energy projects.

TGS has bought a 10% stake in NASH Renewables, a start-up developing innovative Software-as-a-Service (SaaS) solutions for the prospecting, construction and operations of wind energy projects.

The equity stake in NASH Renewables is TGS’ first investment into a renewable energy start-up.

TGS has acquired a 10% equity stake in NASH Renewables, with an option to increase to 20%, subject to pre-defined milestones.

NASH is a new artificial intelligence software company established in Germany in 2022 by three founders with long track records in developing digital solutions for the global wind energy industry. The company is led by former Siemens Gamesa chief digital officer Daniel Luecht.

NASH is developing a novel concept by bringing the technology and electricity market ecosystems together. Combining various data feeds, from weather and energy markets to individual turbine fatigue loads, NASH will optimize asset configuration and maximize the energy value obtained, resulting in significantly higher investment returns in post-subsidy energy markets.

NASH’s AI software solutions will enable wind asset developers and investors to pivot their decision-making processes on optimizing output during periods of high energy demand rather than pursuing the highest possible annual production volume, said TGS. The choices unlock FIRST

significantly higher value – not only for the market, grid and investors but also for decarbonizing global energy supply, the company added.

Daniel Luecht, founder and CEO of NASH Renewables, said: ‘Renewable energy faces a massive growth challenge to successfully limit global warming. At the same time, renewable energy is transitioning into the post-subsidy era, instead of benefiting from fix-price remuneration schemes, the value of green energy will increasingly be determined by hourly or even quarter-hourly electricity market prices. Even better, hourly electric prices represent a powerful incentive to increase the decarbonization impact of new renewable energy asset deployments.’

Jan Schoolmeesters, EVP of digital energy solutions at TGS, said: ‘Our ambition is to become a global leader in data-driven solutions across the energy value chain. So, we need to explore disruptive technologies and business models and learn from the most innovative entrepreneurs. We now have a partnership with a highly experienced founders’ team developing SaaS solutions that could revolutionize how wind energy projects are planned, built and operated.’

Within its New Energy Solutions business unit established in 2021, TGS has developed an insight platform, WindAXIOM, to help offshore wind energy developers and stakeholders evaluate the viability of potential projects by analysing multiple resource and risk factors. Additional cross-platform functionalities can be developed with the support of NASH’s team. Further synergies can be gained by improving the predictive functions of the software platform. With its large quantities of modelled and observational data, TGS can help to enhance artificial intelligence algorithms for forecasting.

TGS recently developed and introduced additional data-driven solutions for offshore wind and fully acquired two companies: 4C Offshore Ltd (offshore wind market intelligence) and Prediktor As (real-time data management and asset management solutions for solar PV, wind and oil and gas projects).

TGS delivers East Coast India reprocessing project

Offshore Chennai, Bay of Bengal, is one of the areas covered by the project.

TGS has delivered the first phase of its East Coast India reprocessing project.

Final 2D-cubed, workstation-ready data

was due to be delivered by the end of July 2022.

The TGS East Coast India 2D-cubed project comprises hundreds of thousands of kilometres of existing 2D data across an area of more than half a million square kilometres offshore India’s east coast. The project utilizes TGS’ proprietary 2D-cubed technology – a solution for generating a 3D seismic migration volume from a set of 2D seismic lines – to create a single conformable, easily accessible dataset designed to encourage and assist exploration endeavours offshore India, said TGS.

Will Ashby, executive vice-president, Eastern Hemisphere at TGS, said: ‘The new dataset is one of many TGS initiatives providing seismic to boost exploration across Asia. It will allow explorers to better develop regional models in their pre-study evaluation process. Access to this data will also increase confidence in licensing round decision-making processes and maximize the potential of existing seismic data in the region by employing innovative processing techniques.’

Final processed products will be available in Q4 2022

RESERVOIR ENGINEERING & GEOSCIENCE

The need to get the most out of the largest fields has never been a bigger game with more at stake, especially as many frontier exploration projects and schemes for enhancing recovery of existing fields have become more viable in recent months.

As a result, geoscientists need to raise the bar in terms of the ingenious reservoir geoscience and engineering solutions that they apply. This month we look at the solutions available to petroleum engineering engineers, including established techniques as well as increasing use of machine learning.

Blowing hot and cold over the Energy Transition John M. Reynolds, Managing Director at Reynolds International Ltd., considers tidal range as a key renewable component of the Energy Transition.

The challenge With unprecedented costs for electricity (£9,724/MWh), imminent blackouts amid insufficient energy supply, growing global geopolitical insecurity, and an increasingly evident climate crisis, the Energy Transition debate is more relevant than ever. The hydrocarbon industry is using its resources to develop carbon capture and storage, but this will only manage some of the CO2 being generated; it does not help to reduce the enormous volumes being produced. Similarly, in 2021 atmospheric concentrations of methane tripled in comparison with pre-industrial levels to more than 1,900 ppb. Methane is 20 times more damaging than CO2; 60% of anthropogenic methane is derived from burning fossil fuels, leaky landfills, and gaseous livestock. Modern society is producing too much greenhouse gas and is not doing enough to improve matters anything like as quickly as is required to keep the increase in global average temperatures to <2°C by 2050.

Energy generation portfolio While hydrocarbons will remain important, electricity generation needs to be better able to cope with ever-growing demand while reducing its dependence on fossil fuels. The answer is not to rely as much as governments want on the intermittent energy sources such as wind and solar; more dependable baseload generation is required. Some argue that the answer lies with nuclear, but this is beset by technical challenges, escalating costs, and ever more delays. It also comes with a highly toxic legacy of nuclear waste. Similarly, wind and solar have their environmental costs too – what to do with old turbine blades (43.5 million tonnes to landfill by 2050) and end-of-life (EOL) solar panels? Recycle as

much as possible but continue to dispose the rest in landfills in ever growing numbers? The recently published UK government energy security policy loudly emphasised a renewed push for offshore wind development and more nuclear energy, despite the many issues. Yet governments have successively blown hot and cold in their energy policies, first ramping up capacity aspirations, then threatening windfall taxes on energy producers, and so on. Investors need a more stable environment in which to commit to what are inevitably long-term projects. There are no quick fix solutions.

A solution?

What is needed is a strategically balanced portfolio of energy production that provides energy security and dependence, flexibility to cope with short-term demands, and yet can produce the quantity and quality of base load generation. Clearly there are roles for nuclear as well as for offshore wind and solar power generation to increase installed generating capacity. Yet what is conveniently ignored by government and policy makers is the availability of a major resource right on the UK’s doorstep – tidal energy. The UK, and especially its western coastline, is blessed with some of the highest tidal ranges in the world. While significant progress is being made to develop tidal stream technology – using the lateral flow of tidal currents – it is more suited to smaller capacity energy production in dispersed island settings for example, between mainland Scotland and the Orkneys, rather than as a major energy producer for mainland grids. It is the use of the vertical changes in tidal height – low-head marine hydropower in tidal range – that could yield 10+GW of installed capacity in the UK within a

ensure that power generation can be achieved on both the ebb and flow of each tide. Given the magnitude of the construction works, significant attention is also being paid to reducing the carbon footprint in as many different processes in the supply chain as possible (production of concrete, etc.), with the use of electric or even hydrogen-powered vehicles. Furthermore, unlike other forms of power generation, the lifespan of a tidal range project is typically >120 years and requires no decommissioning of the major infrastructure, thereby removing the environmental downside associated with other power generation techniques.

decade. Tides are predictable for many years ahead and dependable. With a fleet of tidal lagoons to take advantage of the phase lag in tides around the UK, continuous generation could be produced for ~18+ hours a day. When maximum tidal generation occurs out of phase with peak electricity prices, the cheap electricity can be used for electrolysis to produce truly green hydrogen. This can be used to generate more electricity and/or as a fuel itself, such as in public transport or directly by energy-hungry manufacturing industry. One of the most attractive proposed tidal range schemes in the UK is a 2.5 GW scheme proposed along the North Wales coast. In addition to power generation, such projects could provide much-needed protection against coastal flooding, so necessary with rising sea levels, as well as other additive benefits, such as aquaculture, local mussel fisheries, enhanced protection to safeguard vulnerable bird populations, and preservation of shallow marine habitats as the diurnal tidal range would be maintained. The scheme would also provide a tourist attraction through enhanced amenities and an educational visitor centre. It would help to preserve the sandy beaches for which North Wales is famous. An existing tidal range scheme has been operational successfully at La Rance in France for many decades but uses uni-directional flow turbines. Turbine manufacturers are currently developing dual-flow turbines to

Aspiration If the hydrocarbon industry wishes to diversify more effectively into renewable energy, the answer is not necessarily just blowing in the wind. It might be lapping around our ankles at the beach with each rise and fall of the tides. As geoscientists we are well placed to play our part in providing solutions to what is an existential climate crisis. We should all in our various roles do what we can to communicate and lobby to reduce CO2 emissions, diversify the energy generation portfolio to include tidal range, increase energy efficiency, and help to reduce the cost of electricity production and make the world a better place for future generations. Complacency is not an option!
