Global gas: catch methane if you can?

methane leaks

Scaling up natural gas is among the largest decarbonisation opportunities on the planet. But this requires minimising methane leaks. Exciting new technologies are emerging. This 30-page note ranks producers, positions for new policies and advocates developing more LNG. To seize the opportunity, we also identify c25 early-stage companies and 10 public companies in methane mitigation. Global gas demand should treble by 2050 and will not be derailed by methane leaks.

This overview note was first published in 2019, then updated in Feb-2021 and September-2022, to add further case studies, companies and market updates. It contains all our latest views on methane mitigation, in a single, comprehensive resource.


Pages 2-5 explain why methane matters for climate and for the scale up of natural gas. If 3.5% of methane is leaked, then natural gas is, debatably, no greener than coal.

Pages 6-9 quantify methane emissions and leaks across the global gas industry, including a granular breakdown of the US supply-chain, based on asset-by-asset data.

Pages 10-11 outline the incumbent methods for mitigating methane, plus our screen of 34 companies which have filed 150 recent patents for improved technologies.

Pages 12-13 outline the opportunity for next-generation methane sensors, using LiDAR and laser spectroscopy, including trial results and exciting companies.

Pages 14-15 outline the opportunity for next-generation methane sensors, using AI and other ambient data, with a case study that likely offers detection costs below $10/ton CO2e.

Pages 16-18 cover the best new developments in drones and robotics for detecting methane emissions at small scale, including three particularly exciting companies.

Pages 19-20 outline next-generation satellite technologies, which will provide a step-change in pinpointing global methane leaks and repairing them more quickly.

Pages 21-27 cover the changes underway in the oilfield supply chain, to prevent fugitive methane emissions, highlighting interesting companies and innovations.

Pages 28-29 screen methane emissions across the different Energy Majors, and resultant CO2 intensities for different gas plays.

Page 30 advocates new LNG developments, particularly small-scale LNG, which may provide an effective, market-based framework to mitigate most methane.

Our underlying data-files into methane mitigation are also available to be viewed individually, in chronological order, covering company screens, technology reviews and leakage rate data.

Shale growth: what if the Permian went CO2-neutral?

making Permian production carbon neutral

Shale growth has been slowing due to fears over the energy transition, as Permian upstream CO2 emissions reached a new high in 2019. We have disaggregated the CO2 across 14 causes. It could be eliminated by improved technologies and operations, making Permian production carbon neutral: uplifting NPVs by c$4-7/boe, re-attracting a vast wave of capital and growth. This 26-page note identifies the best opportunities.


Pages 2-5 show how fears over the energy transition have slowed down shale growth in 2019.

Pages 6-10 disaggregate the CO2 intensity of the Permian, by source and by operator, based on over a dozen models we have constructed.

Pages 11-15 argue why increased LNG development is the single greatest operational opportunity to reduce Permian CO2 intensity.

Pages 16-18 summarise advances in methane mitigation technologies and their impacts.

Pages 19-23 outline and quantify the best opportunities to lower CO2 from digital initiatives, renewables, lifting and logistics.

Pages 24-25 quantifies the sequestration potential from CO2-EOR, which could offset the remaining CO2 left after all the other initiatives above.

Our conclusion is to identify three top initiatives that companies and investors should favor. Industry leading companies are also suggested based on the patents and technical literature we have reviewed.

Ramp Renewables? Portfolio Perspectives.

optimal portfolios transitioning to renewables.

It is often said that Oil Majors should become Energy Majors by transitioning to renewables. But what is the best balance based on portfolio theory? Our 7-page note answers this question, by constructing a mean-variance optimisation model. We find a c0-20% weighting to renewables maximises risk-adjusted returns. The best balance is 5-13%. But beyond a c35% allocation, both returns and risk-adjusted returns decline rapidly.


Pages 2-3 outline our methodology for assessing the optimal risk-adjusted returns of a Major energy company’s portfolio, including the risk, return and correlations of traditional investment options: upstream, downstream and chemicals.

Page 4 quantifies the lower returns that are likely to be achieved on renewable investment options, such as wind, solar and CCS, based on our recent modeling.

Pages 5-6 present an “efficient frontier” of portfolio allocations, balanced between traditional investment options and renewables, with different risk and return profiles.

Pages 6-7 draw conclusions about the optimal portfolios, showing how to maximise returns, minimise risk and maximise risk-adjusted returns (Sharpe ratio).

The work suggests oil companies should primarily remain oil companies, working hard to improve the efficiency and lower the CO2-intensities of their base businesses.

Decarbonise Downstream?

Decarbonise Downstream Refining Improved Catalysts

Refining has the highest carbon footprint in global energy. Next-generation catalysts are the best opportunity for improvement: uniquely, they could cut refineries’ CO2 by 15-30%, while also uplifting margins, which get obliterated by other decarbonisation approaches. Catalyst science is undergoing a digitally driven transformation. Hence this 25-page note outlines a new ESG opportunity around refining catalyst technologies. Industry leaders are also identified.


Pages 2-3 outline the need to decarbonise the refining industry, in order to clean up the world’s future oil production and preserve access to capital.

Pages 4-6 decompose the sources of CO2 emissions across a typical refinery, process-by-process; as a function of heat, utilities and hydrogen.

Page 7-8 outline small opportunities to improve refinery CO2 intensities, via continued process enhancements, changing crude slates and renewable energy.

Page 9 finds green hydrogen can reduce CO2 emissions by c7-15%, but economics are unfavorable, obliterating refining margins.

Pages 10-12 models the costs of post-combustion carbon capture, which could cut CO2 intensities by 25-90%, but also risks cutting margins by $2-4/bbl.

Pages 13-14 present the opportunity for better catalysts, identifying which Energy Majors have the leading refining technologies, based on patent filings.

Pages 15-17 outline the most promising, emerging catalyst technologies from 50 patents we studied. They can reduce refinery CO2 intensities by 5kg/bbl.

Pages 18-21 highlight breakthrough, digital technologies to improve the development of new catalysts, including super-computing and machine learning techniques.

Pages 23-24 screen 35 leading catalyst companies, including Super-Majors, chemicals companies and earlier-stage pure-plays.

Guyana: carbon credentials & capital costs?

Guyana carbon credentials

Prioritising low carbon barrels will matter increasingly to investors, as they can reduce total oil industry CO2 by 25%. Hence, these barrels should attract lower WACCs, whereas fears over the energy transition are elevating hurdle rates elsewhere and denting valuations. In Guyanaโ€™s case, the upshot could add $8-15bn of NAV, with a total CO2 intensity that could be c50% below the industry average.


Pages 2-3 introduce our framework for decarbonisation of the global energy system. Within oil, this requires prioritising lower carbon over higher carbon oil barrels.

Pages 3-6 outline the economic value in Guyana, which is now at the point where it is hard to move the needle with further resource discoveries.

Pages 7-8 show how lower WACCs can be trasnformative to resource value, even more material than increasing oil prices to $100/bbl.

Pages 9-17 outline the top technologies that should minimise Guyana’s CO2 emissions per barrel, including flaring policies, refining quality, midstream proximity, proprietary gas turbine technologies from ExxonMobil’s patents and leading digital technologies around the industry.

Our conclusion is that leading companies must deepen their efforts to minimise CO2 intensities and articulate these initiatives to the market.

Key points on Guyana carbon credentials and oil capital costs are spelled out in the article sent out to our distribution list.

Investing for an energy transition

Investing for an energy transition

What is the best way for investors to decarbonise the global energy system? We argue this outcome is achievable by 2050. But a new โ€˜venturingโ€™ model is needed, to incubate better technologies. CO2 budgets can also be stretched furthest by re-allocating to gas, lower-carbon oil and lower-carbon industry. But divestment is a grave mistake. These are the conclusions in our new, 18-page report.


The global energy system could be decarbonised by 2050 (chart above). Yet todayโ€™s renewable technologies are only sufficient to meet c15% of the challenge. The largest component, at c50%, requires new energy technologies: both to economize demand and decarbonise supplies, which will most likely remain fossil-dominated to 2100.

Other routes are dangerous. The โ€˜divestment movementโ€™ seeks to cut off capital for fossil fuels. This does not yield an energy โ€˜transitionโ€™, but a devastating energy โ€˜shortageโ€™. Scaling up new technologies requires more capital, not less (see pages 2-7 in the PDF).

Is the investment community configured for energy transition? We fear not.

First, the investment process should favour lower-carbon suppliers across every industry, to incentivise efficiency. Within energy, this includes natural gas, low-carbon oil over higher-carbon oil (saving 500MTpa of CO2) and technology-leaders (see pp 8-11).

A new breed of venture funds is most needed, so investors can allocate capital to economically promising technologies. These opportunities are extremely exciting, based on all of our research. For example, we argue leading Energy Majors should offer up co-investments in their venture funds (see pp 12-16).

Drones & droids: deliver us from e-commerce

Drones and Droids Impact on Retail

Small, autonomous, electric delivery vehicles are emerging. They are game-changers: rapidly delivering online purchases to customers, creating vast new economic possibilities, but also driving the energy transition. Their ascent could eliminate 500MTpa of CO2, 3.5Mboed of fossil fuels and c$3trn pa of consumer spending across the OECD. The mechanism is a re-shaping of urban consumption habits, retail and manufacturing. The opportunities are outlined in our new, 20-page report.


The average US consumer buys 2.5 tons of goods per year, served by a vast distribution network of ships, trucks and smaller vehicles, collectively responsible for 1.5 barrels of oil, $1,000 of cost and 600kg of CO2 per person per annum (page 2).

Fuel economy currently deteriorates, with each step closer to the consumer. Container ships achieve c900 ton-miles per gallon of fuel. But delivery vans, the dominant delivery mechanism for internet purchases, are least efficient, achieving just 0.02 effective ton-mpg and costing at least $3.6 per delivery (page 3).

The rise of e-commerce has already increased supply chain CO2 by c30%, and supply chain costs by 2x since the pre-internet era. On today’s technologies, CO2 will rise another 20% and cost will rise another 50% by 2030, adding 0.7Mbpd of oil demand, 120MTpa of CO2 and $500bn of cost across the OECD (pages 4-5)

Drones and droids are 90-99% less energy intensive than delivery vans, and 70-97% less costly. The technology is maturing. Thus small, autonomous, electric vehicles will move immediately, efficiently, straight to their destination (pages 6-8).

Retail and manufacturing will have be transformed by the time drones approach 50% market share in last-mile delivery. Tipping-point economies-of-scale mean that they will take market share away from cars and delivery vans very rapidly (pages 9-10).

The second half of the report focuses in on the opportunities. Retail businesses must consolidate, specialise or diversify to “sharing” models. The latter can save $1trn of consumer spending and 100MTpa of emissions in the US alone (pages 11-20).

2050 oil markets: opportunities in peak demand?

long run oil demand

Many commentators fear long-run oil demand is on the cusp of a steep contraction, leaving oil and gas assets stranded. We are more concerned about the opposite problem. Projecting out the current trends, global oil demand is on course to keep rising to over 130Mbpd by 2050, undermining attempts to decarbonise the worldโ€™s energy system.

Our new, 20-page note reviews seven technology themes that can save 45Mbpd of long-term oil demand. We therefore find oil demand would plateau at 103Mbpd in the 2020s, before declining gradually to 87Mbpd in 2050. This is still an enormous market, equivalent to 1,000 bbls of oil being consumed every second.

Opportunities abound in the transition, in order to deliver our seven themes, improve mobility, substitute oil for gas, reconfigure refineries for changing product mixes, and to ensure that the world’s remaining oil needs are supplied as cleanly and efficiently as possible. Leading companies will seize these opportunities, driving the transition and earning strong returns in the process.

US Shale: No Country for Old Completion Designs

Shale productivity gains

2019 has evoked resource fears in the shale industry. They are unfounded. Even as headline productivity weakened, underlying productivity continues improving at an exciting pace. These conclusions are substantiated by reviewing 350 technical papers, published by the shale industry in summer-2019. Major improvements are gathering momentum, in shale-EOR, machine learning techniques, digitalization and frac fluid chemistry.


Discussed companies include Apache, BP, Conoco, Chevron, Devon, ExxonMobil, Halliburton, Occidental, Pioneeer & Schlumberger.

Page 2 compares 2019’s shale performance to-date with our January forecasts, identifying that initial-month producutivity has been 20% weaker YoY.

Page 3-4 shows how continued productivity improvements matter, to unlock >20Mbpd of potential US shale output, plus $300bn of FCF by 2025 (at $50/bbl oil).

Pages 5-8 explain away the apparent degradation in resource productivity: it is a function of three alterations to completion designs.

Pages 9-12 outline 350 technical papers from the shale industry in summer-2019. They restore confidence: the industry is not facing systemic resource issues.

Page 12 covers 24 technical papers into “parent-child” issues. We were surprised by the number that were ‘negative’ versus the pragmatic solutions offered in others.

Page 13, 14 & 17 cover leading digitalization technologies: deployment of machine learning increased 5x YoY, while DAS/DTS increased 3x YoY in 2019.

Pages 14-16 cover the maturation of shale-EOR, which was the greatest YoY improvement, reaching 32 papers in 2019. The cutting-edge of EOR is exciting.

Page 18 outlines other technical highlights to drive future productivity higher.
