Rystad: US methane fee could cost oil and gas firms US$1 billion in 2025
The methane fee, part of the amended text of the Build Back Better Act released by the US House Rules Committee, could cost the petroleum and natural gas industry US$1.3 billion in 2025 under a status quo scenario, according to Rystad Energy analysis.
While the latest draft bill relaxes some of the previously proposed regulations, it will still have a profound economic impact, especially on smaller onshore producers.
Even though the proposed bill would go into effect in 2023, the phased introduction – 60% in 2023, 80% in 2024, and 100% in 2025 – means the full effect would not be felt until the middle of the decade.
The US$1.3 billion estimated cost impact in 2025 assumes producers continue output and methane intensity at 2019-2020 levels on average. Methane intensity is improving quickly, Rystad Energy noted.
“The actual impact in 2025 will be south of US$1 billion based on base case production growth and expected improvements in methane intensity. It is important to point out that the real impact will be biased even more towards smaller producers and conventional legacy fields in contrast to what the current status quo suggests,” said Artem Abramov, head of shale research at Rystad Energy.
Methane intensity is improving quickly for most companies based on the Subpart W accounting methodology, so by 2025 many key producers will be under intensity thresholds proposed in the latest version.
On the other hand, the Environmental Protection Agency (EPA) still has a plan to decrease the Subpart W reporting threshold from to 10,000 tonnes of CO2e/year from 25,000. If implemented, a larger number of smaller producers will be included in the methane fee calculation, as they typically have higher methane intensity levels than their larger peers.
“Despite its impact – when compared to the original methane bill introduced in March 2021 – the revised methane fee is a much softer proposal that introduces arguably a more justified formula for calculation,” Mr Abramov said.
To understand the potential economic implications for the industry, it is important to consider how the sector has been progressing in methane intensity – the ratio of methane emissions to natural gas produced – as per the Subpart W reporting standards.
The industry has steadily improved its methane intensity since 2016, especially the larger producers.
Rystad Energy analysis estimates only US$7.5 million in annual costs per operator for large producers—roughly the equivalent of drilling one two-mile long horizontal well in the Midland basin today.
“If we convert these numbers into variable incremental costs or normalise to production levels, the average impact is only 4¢/boe, on a gross operated three-stream basis, with only a handful of large producers seeing an impact above 10¢/boe, based on their 2019-2020 performance.”
Going by the steady methane intensity improvements the industry delivered between 2016 and 2020, it would be no surprise if most large operators fall below the minimum emissions in the first year of the new rule.
“For this reason, we predict the number of key oil and gas producers that will be subject to the proposed fee – those with methane intensity levels above the allowed thresholds of 0.2% for production and 0.05% for gathering & boosting – will be relatively low.
Thus, even in a status quo scenario, where the industry’s performance holds as is, the annual US$1.3 billion methane fee will largely be borne by smaller producers, who will still qualify for reporting requirements under Subpart W,” according to Mr Abramov.
“If the EPA extends the reporting requirement of the methane fee plan and lowers the threshold from 25,000 to 10,000 tons CO2e per year, the annual impact on the industry would exceed US$1 billion even in a scenario where performance improves continuously. In such a case, the proposal’s economic impact will be biased even more towards smaller producers,” he concluded.
