repurpose abandoned – With thousands of abandoned oil and gas wells still damaging groundwater and releasing methane, U.S. states are weighing whether those sites can be converted into geothermal heat and other underground energy uses—an idea that promises cleaner power but comes w
When policymakers describe abandoned wells, the language is rarely hopeful.. Oklahoma regulators. for instance. estimate there are more than 20. 000 orphan sites—many with unclear ownership—and they warn that shutting down the damage would take 235 years and hundreds of millions of dollars.. For states seeking clean. reliable energy. the question now is whether those already-drilled holes could become part of the solution. rather than a long-running liability.
Across the country. legislators in Republican- and Democratic-led states are exploring pathways to repurpose inactive oil and gas wells for geothermal heat and. in some cases. underground energy storage.. The basic attraction is straightforward: the wells are already in the ground. and regions with long histories of oil and gas production have subsurface data geothermal developers can use to plan where and how to build carbon-free systems.
The approach is still new and largely untested, but it’s starting to move from concept to policy.. Oklahoma’s state Senate is considering a bill that would create a process for companies to buy abandoned oil and gas wells and repurpose them for geothermal energy or underground energy storage.. The state House passed the measure in March. and the Well Repurposing Act is modeled on New Mexico’s last-year law aimed at its 2. 000-plus orphan wells.
Oklahoma’s scale is part of what makes the bill compelling—and daunting.. State regulators estimate it would take 235 years and hundreds of millions of dollars to plug all of the wells identified there.. The cost to fix a single old well is estimated at $75,000 to $150,000 or more, depending on location and cleanup complexity.. Dave Tragethon. communications director for the nonprofit Well Done Foundation. said the measure is built around a blunt reality: “These wells are a liability. and that there may be a way to turn them into some sort of revenue generation and give them value.” He added that. in his view. “if there’s value. that means there’s more of a willingness to address them and more of an opportunity to raise funding.”
Alabama’s legislature has already taken a step in the same direction.. Lawmakers there passed a measure last month that allows the state to approve and regulate conversion of oil and gas wells for alternative energy resources like geothermal.. North Dakota adopted a bill last year requiring a legislative council to study the feasibility of using nonproductive wells to generate geothermal power.. In Colorado. state agencies have launched a technical study to evaluate the potential of repurposing old wells for geothermal development and carbon capture and sequestration.
Even as these proposals gain traction. the tension is hard to ignore: many inactive wells are still polluting groundwater and leaking methane. while the country has “barely scratched the surface” in dealing with the problem.. The geothermal idea may offer a new purpose for existing infrastructure. but it doesn’t erase the fact that the wells were abandoned for reasons tied to contamination and uncertainty.
The pattern in the policy moves is consistent: states are pairing large inventories of orphan wells with new legal tools or study requirements—Oklahoma through the Well Repurposing Act. Alabama through an approval and regulation framework. North Dakota through a legislative feasibility study. and Colorado through technical analysis—while the underlying motivation remains the same cleanup challenge and the promise of geothermal energy.
Geothermal systems themselves rely on circulating fluids underground to capture naturally occurring heat.. That heat can then be used to drive turbines for electricity or to warm air and water in buildings directly.. Support is also being fueled by industry advances that have made geothermal more technically possible or financially viable in more places.. Recent drilling breakthroughs. however. have been powered largely by the oil and gas sector: drilling engineers and geoscientists. along with deep corporate resources. have helped launch startups and deploy advanced systems.
That’s where the strain enters.. As momentum builds for geothermal—along with bipartisan interest that has largely remained “unscathed” by the Trump administration’s efforts to block renewable energy projects—the expertise and funding from oil and gas has mostly gone into building new projects.. The question that states are now putting on the table is whether it can be redirected toward the mess already left behind: figuring out how to retool leaky wells from earlier eras into carbon-free systems without repeating the same failures that created the orphan-well crisis in the first place.
