EPA’s Quad O regulations expected to trigger tsunami of plugged wells

EIR advises investors and operators to start modeling implications immediately

byEnverus

CALGARY, Alberta (Feb. 7, 2024) — Enverus Intelligence Research (EIR), a subsidiary of Enverus, the most trusted energy-dedicated SaaS company, has released a report that details the impact that the EPA’s Quad O regulations will have on upstream oil and gas producers in the U.S.

“The EPA’s recently finalized Quad O regulations will raise fixed costs, pushing lower producing wells into uneconomic territory later this decade when it is fully implemented,” said John Gutentag, product owner at EIR.

“EIR modeled that 34% of actively producing wells in the Lower 48 states will see additional costs of at least $10 per boe, a threshold we believe makes the wells potentially uneconomic, leading to accelerated plugging and abandonment timelines and an inevitable influx of orphaned wells,” said Gutentag.

Key takeaways:

  • EIR concludes the EPA’s Quad O regulations represent a step change that will accelerate plugging and abandonment (P&A) timelines, and investors and operators should start modeling these implications now.
  • EIR estimates the monitoring and amortized capital costs of retrofitting process controllers alone will add more than $10/boe in costs to 34% of actively producing wells, a threshold we classify as potentially turning the wells uneconomic. These wells, however, represent only 0.4% of U.S. production.
  • EIR finds 46% of producers (5,163 companies) that account for 21.7% of Lower 48 unplugged wells face concerning plugging liabilities with an undiscounted well-plugging liability exceeding $100,000/boe/d (20:1 basis).
  • Given these costs, EIR expects many of these operators will struggle to fund the accelerated plugging timelines, likely forcing bankruptcies and increasing the number of orphaned wells.
  • Operators with a large base of newer producing wells will be far less impacted by the operational changes. We estimate wells that represent 95.2% of U.S. production will add less than $1/boe in costs.
