As you wish deprived of a much-needed supply of immaculate, reliable energy, some are turning to an unconventional source: abandoned oil and gas wells used to generate geothermal heat.
These are millions of inactive wells littered all over the United Statesremnants of earlier eras of fossil fuel production. A huge number of landfills have no official owner, and many continue to pollute groundwater and leak heat-trapping methane. The country has barely come close to solving this problem.
Policymakers in Republican- and Democratic-led states are examining whether the sites could instead be turned into recent wells to produce geothermal energy. After all, the holes are already drilled in the ground. And regions with extensive oil and gas production have the opulent underground data that geothermal companies need to determine where and how to build their zero-emission systems.
The concept is relatively recent and largely unproven, although scientists and startups are we are working to change this. Countries are also laying the groundwork for action by lifting regulatory hurdles and launching detailed studies.
In Oklahoma, the state Senate is considering Bill this would create a process for companies to purchase abandoned oil and gas wells and reuse them for geothermal energy or underground energy storage. More than 20,000 such wells have been identified in Oklahoma, and state regulators estimate it would take 235 years and hundreds of millions of dollars to plug them all. By some calculations, repairing a single ancient well could cost anywhere from $75,000 to $150,000 or more, depending on where it is located and how sophisticated it is to immaculate.
The Well Repurizing Act, which was passed by the Oklahoma House of Representatives in March, is modeled on: similar law adopted last year by Novel Mexico to address the problem of more than 2,000 orphan wells.
The Oklahoma bill “recognizes that these drilling operations are a burden and that there may be a way to turn them into generating revenue and giving them value,” said Dave Tragethon, the nonprofit’s communications director Good Work Foundationwhich finds and fills abandoned oil and gas wells throughout the country. “And if there is value, it means there is a greater willingness to address them and a greater chance of getting funding.”
In Alabama, legislators passed the act last month that allows the state to approve and regulate the conversion of oil and gas wells to exploit alternative energy sources such as geothermal energy. North Dakota adopted the bill Last year, it required the Legislative Council to study the feasibility of using non-producing wells to generate geothermal energy. And in Colorado, it’s just state agencies launched a technical inspection assessing the potential to repurpose ancient wells for geothermal development and carbon capture and sequestration.
These efforts reflect the growing bipartisan support for geothermal energy that is largely taking place remained intact the Trump administration’s efforts to block renewable energy projects. Energy resources can facilitate meet the nation’s growing energy needs while reducing planet-warming greenhouse gas emissions.
Well conversion is tempting but complicated
Geothermal systems work by circulating fluids underground to capture naturally occurring heat, which can then be used to drive turbines to generate electricity or to directly heat the air and water in buildings. There is industry is gaining momentum thanks to recent advances in drilling methods and technologies that enable technically or financially viable access to geothermal energy in more places.
Many of these breakthroughs have occurred in the oil and gas industry, which skilled labor drilling engineers and geologists, as well as deep corporate pockets, helped launch startups and implement cutting-edge systems. However, most of this knowledge and funds go to building recent projects, without considering how to repair the leaky wells left by earlier generations.
