US CO2 and Methane Intensity by Basin

US CO2 and Methane Intensity by Basin

The CO2 intensity of oil and gas production is tabulated for 425 distinct company positions across 12 distinct US onshore basins in this data-file. Using the data, we can break down the upstream CO2 intensity (in kg/boe), methane leakage rates (%) and flaring intensity (mcf/boe), by company, by basin and across the US Lower 48.


In this database, we have aggregated and cleaned up 957 MB of data, disclosed by the operators of 425 large upstream oil and gas acreage positions. The data are reported every year to the US EPA, and made publicly available via the EPA FLIGHT tool.

The database covers 70% of the US oil and gas industry from 2021, including 8.8Mbpd of oil, 80bcfd of gas, 22Mboed of total production, 430,000 producing wells, 800,000 pneumatic devices and 60,000 flares. All of this is disaggregated by acreage positions, by operator and by basin. It is a treasure trove for energy and ESG analysts.

CO2 intensity. The mean average upstream oil and gas operation in 2021 emitted 10kg/boe of CO2e. Across the entire data-set, the lower quartile is below 3kg/boe. The upper quartile is above 13kg/boe. The upper decile is above 20kg/boe. And the upper percentile is above 70kg/boe. There is very heavy skew here (chart below).

The main reasons are methane leaks and flaring. The mean average asset in our sample has a methane leakage rate of 0.21%, and a flaring intensity of 0.03 mcf/bbl. There is a growing controversy over methane slip in flaring, which also means these emissions may be higher than reported. Flaring intensity by basin is charted below.

US CO2 intensity has been improving since 2018. CO2 intensity per basin has fallen by 17% over the past three years, while methane leakage rates have fallen by 22%. Activity has clearly stepped up to mitigate methane leaks.

(You can also see in the data-file who has the most work still to do in reducing future methane leaks. For example, one large E&P surprised us, as it has been vocal over its industry-leading CO2 credentials, yet it still has over 1,000 high bleed pneumatic devices across its Permian portfolio, which is about 10% of all the high-bleed pneumatics left in the Lower 48, and each device leaks 4 tons of methane per year!).

Most interesting is to rank the best companies in each basin, using the granular data, to identify leaders and laggards (chart below). A general observation is that larger, listed producers tend to have lower CO2 intensity, fewer methane leaks and lower flaring intensity than small private companies. Half-a-dozen large listed companies stand out, with exceptionally low CO2 intensities. Please consult the data-file for cost curves (like the one below).

Methane leaks and flaring intensity can also be disaggregated by company within each basin. For example, the chart below shows some large Permian producers effectively reporting zero flaring, while others are flaring off over 0.1 mcf/bbl.

All of the underlying data is also aggregated in a useful summary format, across the 425 different acreage positions reporting in to EPA FLIGHT, in case you want to compare different operators on a particularly granular basis.

US shale production forecasts by basin?

US shale production forecasts by basin

This model sets out our US shale production forecasts by basin. It covers the Permian, Bakken and Eagle Ford, as a function of the rig count, drilling productivity, completion rates, well productivity and type curves. Thus, we derive production and financial expectations.


Production. At the start of 2022, we hoped the big three US shale basins would surpass 10.0 Mbpd of liquids production by Sep-22. The latest estimate is 9.2Mbpd. A 0.8Mbpd disappointment.

Activity is the main reason. At the start of 2022, we hoped the oil rig count in these three basins would end October at 520 units, up 3.5x from the troughs of 2020. We only have about 460.

Well productivity cannot be faulted. We thought the average shale well would be IP-ing at 0.81 kbpd. The average has come in at 0.90kbpd. All three basins beat our forecasts. Bakken most so.

DUC drawdowns cannot continue forever. We anticipated 1.03 wells might get completed for every 1 well drilled in 2022. The YTD ratio is 1.11x. At 2,200, DUC count is now at its lowest since 2013.

Most strikingly, we now see 2025 shale production at 15Mbpd, 10Mbpd below the high potential seen in 2018-19, due to the whipsawing effects of COVID, and hesitancy over long-term investment.

This might support expectations for a “weird recession” in 2022-24, where economic activity is weak, but traditionally cyclical commodity prices de-couple, to incentivize needed investment?

Our longer-term numbers hinge on the productivity gains described in our thematic shale research. Shale productivity trebled from 2012-2018. We think it can rise another 45% by 2025, unlocking 15Mbpd of liquid shale production. However productivity could disappoint mildly in 2022 as the industry ramps activity levels back post-COVID.

We have also modeled the Marcellus and Haynesville shale gas plays, using the same framework, in a further tab of the data-file. Amazingly, there is potential to underpin a 100-200MTpa US LNG expansion here, with 20-50 additional rigs.

Shale productivity: snakes and ladders?

Shale Productivity Snakes and Ladders

Unprecedented high-grading is now occurring in the US shale industry, amidst challenging industry conditions. This means 2020-21 production surprising to the upside, and we raise our forecasts +0.7 and +0.9Mbpd respectively. Conversely, when shale activity recovers, productivity could disappoint, and we lower our 2022+ forecasts by 0.2-0.9 Mbpd. This 7-page note explores the causes and consequences of this whipsaw effect.

Oil markets: finding the balance?

oil market supply demand balance

Our oil market supply demand balance is informed by a 45-line model, running month-by-month out to 2025. This download contains both the model, and a 4-page summary of our outlook, from mid-2021.


After ten years forecasting oil markets, our humble conclusion is that all oil models are wrong. Some are nevertheless useful. To be most useful, our model takes a Monte Carlo approach to the key uncertainties, to quantify the “risk” of positive and negative surprises (illustrative example below).

Please download the model to see, and to flex our input assumptions. Included with the download is a PDF summary of our oil price thesis in mid-2021,  which is also available separately, linked here.

Important note. The past 2-3 years have been a nightmare for oil market supply demand balance forecasting. We think there is over 3Mbpd of oil demand pent up still to recover in 2022+ from post-COVID. Also, to state the obvious, if there is a major disruption to Russian oil supplies, then oil markets will be under-supplied. And so we do not think we can currently add value by ‘forecasting’ oil markets at all in 2022. We will re-visit this topic in depth in 2023.

Chevron: SuperMajor Shale in 2020?

Chevron Shale Technologies

SuperMajors’ shale developments are assumed to differ from E&Ps’ mainly in their scale and access to capital. Access to superior technologies is rarely discussed. But new evidence is emerging. This note assesses 40 of Chevron’s shale patents from 2019, showing a vast array of data-driven technologies, to optimize every aspect of shale.

CO2 Intensity of Oilfield Supply Chains

Oilfield Supply Chain CO2 per barrel

This data-file calculates the CO2 intensity of oilfield supply chains, across ten different resources, as materials are transported to drilling rigs, frac crews, production platforms and well pads.

Different resources can be ranked on this measure of supply chain CO2-intensity: such as  the Permian, the Gulf of Mexico, offshore Norway, Guyana, pre-salt Brazil and Middle East onshore production (chart above).

Underlying the calculations are modeling assumptions, for both onshore and offshore operations, each based on c15 input variables. You can change the inputs to run your own scenarios, or test the most effective ways to lower supply-chain CO2.

Permian CO2 Emissions by Producer

Permian CO2 Emissions by Producer

This data-file tabulates Permian CO2 intensity based on regulatory disclosures from 20 of the leading producers to the EPA in 2018. Hence we can  calculate the basin’s upstream emissions, in tons and in kg/boe.

The data are fully disaggregated by company, across the 20 largest Permian E&Ps, Majors and independents; and across 18 different categories, such as combustion, flaring, venting, pneumatics, storage tanks and methane leaks.

A positive is that CO2 intensity is -52% correlated with operator production volumes, which suggests CO2 intensity can be reduced over time, as the industry grows and consolidates into the hands of larger companies.

US Shale Gas to Liquids?

US shale gas to liquids

We have reviewed 40 of Shell’s GTL patent filings for 2018. They show continued progress, innovating new fuels, lubricants, renewable-heavy gasolines, waxes and detergents. Each patent is summarised and categorized in this data-file.

All of this begs the question whether there is a commercial rationale for a US replica of the Pearl GTL project, to handle the over-abundance of gas emanating from the Permian; and produce these advantaged products. It would also help reduce the risk of US LNG projects glutting the market.

We therefore model the economics in this data-file, using prior project disclosures and our learnings from the patent history. Our base case IRR is 11%, taking in 1.6bcfd of shale gas as feedstock. Resiliency is tested at varying oil and gas prices.

The cutting edge of shale technology?

shale technology technical papers

The database evaluates 950 technical papers that have been presented at shale industry conferences from 2018-2020.  We have summarised each paper, categorized it by topic, by author, by basin, ‘how digital’ and ‘how economically impactful’ it is.

The aim is to provide an overview of shale R&D, including the cutting edge to improve future resource productivity. We estimate 2020 was the most productivity-enhancing set of technical papers of any year in the database.

Recent areas of innovation include completion design, fracturing fluids, EORand machine learning. We also break down the technical papers, company-by-company, to see which operators and service firms have an edge (chart below).

CO2-EOR in Shale: the economics

CO2-EOR in shale

We have modelled the economics of CO2-EOR in shale, after interest in this topic spiked 2.3x YoY in the 2019 technical literature. Our deep-dive research into the topic is linked here.

The economics appear positive, with a 15% IRR under our base case assumptions, and very plausible upside to 25-30%.

There is potential to sequester 3.5bn tons of CO2 in shale formations in the US, plus another 40bn tons internationally, for a CO2 disposal fee of c$40/ton, which we have quantified based on the technical literature.

The model also allows you to stress-test your own assumptions such as: oil prices, gas prices, CO2 prices, CO2 tax-credits, compressor costs and productivity uplift. The impacts on IRR, NPV and FCF are visible.
