Methane emissions from pneumatic devices, by operator, by basin

Methane leaks from 1M pneumatic devices across the US onshore oil and gas industry comprise 50% of all US upstream methane leaks and 15% of all upstream CO2. This data-file aggregates data on 500,000 pneumatic devices, from 300 acreage positions, of 200 onshore producers in 9 US basins.

The data are broken down acreage position by position, from high-bleed pneumatic devices, releasing an average of 4.1T of methane/device/year to pnuematic pumps and intermediate devices, releasing 1.4T, through to low-bleed pneumatic devices releasing 160kg/device/year.

It allows us to rank operators. Companies are identified, with a pressing priority to replace medium and high bleed devices. Other companies are identified with best-in-class use of pneumatics (chart below). The download contains 2018 and 2019 data, so you can compare YoY progress by company.

A summary of our conclusions is also written out in the second tab of the data-file. For opportunities to resolve these leaks and replace pneumatic devices, please see our recent note on Mitigating Methane.

US CO2 and Methane Intensity by Basin

CO2 and methane intensities are tabulated for 300 distinct company positions across 9 distinct basins in this data-file. Using the data, we can aggregate the total CO2 in (kg/boe) and methane leakage rates (as a percent of natural gas production) across the US’s different basins.

Covered basins include the Permian, Bakken, Eagle Ford, Marcellus/Utica, Alaska, GoM, Powder River, San Juan, Anadarko basin and DJ basin (chart above).

It is possible to rank the best companies in each basin, using the granular data, to identify industry leaders and laggards (chart below).

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.

Do “digital” completions lift Permian IRRs?

We have modelled the economic uplift of extra digital instrumentation on a typical Permian well. If the data can uplift production by 2.5%, then c$0.4M of instrumentation costs would “pay back” (i.e., break even). If the data can uplift production by 10%, it would add +$1M of NPV and +5% IRR per well. These numbers are all shown at $50/bbl, but you can flex the inputs in our model.
