The Railroad Commission of Texas has reported runaway costs for plugging and remediating so-called “orphan” wells. The commission estimates that it will cost $202 million to plug its inventory of orphan wells approved for state-funded remediation and decommissioning, the highest total in the program’s history. (See Figure 1.) Texas is on a well-plugging hamster wheel whose liability has grown with each passing year.
The commission, which was given authority over Texas oil pipelines in 1917 and oil production in 1919, considers an oil or gas well orphaned if it has produced no hydrocarbons for a year and its paperwork has been delinquent for the same period. Each year, the agency approves a portion of those orphaned wells to its cleanup rolls for plugging and estimates its obligations based on the projected plugging costs for each included well.
The rising cost of plugging orphan wells can be traced to three trends: a rising number of confirmed orphans approved for plugging, an increasing average depth of orphan wells added, and a rapid increase in the average cost of individual wells. As of March 2026, the Railroad Commission had approved state-funded plugging for 3,632 orphan wells, an all-time high. The average depth of plugged orphaned wells increased 61 percent over the decade to 3,062 feet, also a record. Finally, per-well plugging costs have soared from $23,807 in 2016 to $55,629 in 2026.
These three trends—more orphan wells, deeper orphan wells, and higher plugging costs—have combined to increase the state’s plugging liability by an average of 22 percent per year since 2016. As this trend continues, taxpayers will subsidize the multi-million-dollar costs of plugging orphans and remediating associated soil and water contamination—all while the remaining cost of plugging the backlog of orphans continues to grow.
All told, from 1984 through March 2026, Texas spent $575 million to plug 47,757 orphaned wells left behind by noncompliant or defunct oil and gas operators.
The state’s skyrocketing orphan well liability can be traced to an oil and gas industry that collectively shirks its cleanup responsibilities (leading to orphaned oil and gas wells) faster than plugging occurs. The March 2026 RRC Monthly State Managed Plugging Report shows 156,664 shut-in/inactive wells, with 46 percent of active well operators having more than 25 percent of their wells inactive.
Recognizing the growing fiscal challenge facing the Railroad Commission, the Texas Legislature appropriated a one-time $100 million infusion into the State Managed Plugging Program last year. This means that the cost of cleaning up orphan wells is increasingly falling on the state’s taxpayers, rather than on the oil and gas companies that originally drilled the wells and profited from their production.
