Oil Workers Find New Purpose Drilling for Geothermal Energy

Mike Fleming spent a decade drilling wells in New England, but he never imagined those same skills would land him at the frontier of renewable energy. When his boss recommended him for a geothermal drilling position in late 2024, Fleming discovered something remarkable: the job felt familiar.

"You're making a hole in the ground, you're putting some plastic pipe down there, and you're sealing the hole," Fleming explained. But what seems routine is actually revolutionary.

Geothermal energy works by drilling into the earth to access consistent underground temperatures. Conventional systems drill 200 to 500 feet to find rock between 50 and 60 degrees Fahrenheit, perfect for heating and cooling homes year-round.

The real excitement happens deeper down. Enhanced geothermal drilling reaches thousands of feet underground, where rock temperatures hit 750 degrees Fahrenheit. That's hot enough to power entire buildings, factories, and communities.

Here's the best part: up to 300,000 oil and gas workers already have the skills needed for these jobs, according to a 2024 Department of Energy report. The same expertise that powers fossil fuel extraction transfers directly to drilling for heat.

Cindy Taff spent 35 years at Shell before co-founding geothermal startup Sage Geosystems in 2020. She sees drillers, geologists, and technical experts from the oil industry fitting seamlessly into renewables.

"The oil and gas industry over the last 100 years has really done a lot of innovative stuff," Taff said. That century of technical knowledge is now fueling clean energy growth.

The timing couldn't be better. While other renewables face political headwinds, geothermal is earning bipartisan support. The recent federal bill preserved its tax credits through 2033, and the Department of Energy just announced $171.5 million for next generation field tests.

The domestic geothermal workforce has grown to 8,870 people, with 145,000 employed globally. Drilling companies are already recognizing the opportunity and moving workers between projects.

The Ripple Effect

Brock Yordy, a third generation driller who founded the Geothermal Drillers Association, compares the skill transfer to hanging a painting on different walls. The materials might change, but the fundamentals stay the same.

He sees workers getting in on the ground floor of something special. "By 500 feet, you're drilling a piece of the subsurface that hasn't been touched in 25,000 to 100,000 plus years," Yordy said. "It's like being Indiana Jones."

Researchers like Jonathan Ajo-Franklin at Rice University point out another advantage: geothermal fracking requires minimal wastewater reinjection, avoiding the earthquake risks that plagued oil and gas disposal in Oklahoma and West Texas.

Jamie Beard, executive director of advocacy group Project InnerSpace, hosted an event called MAGMA last year to unite industry leaders and policymakers. Energy Secretary Chris Wright expressed clear support for the technology.

Beard sees massive potential in powering data centers with geothermal. "Oil and gas looks at that opportunity and says, 'Well, hell, if we're cranking out these projects and they're natural gas, why can't we crank out these projects and they could also be geothermal?'"

For workers like Fleming, it's a chance to use familiar skills for something fundamentally different: building a cleaner energy future while keeping paychecks steady and careers thriving.
