University of Oklahoma researchers unveil potential geothermal drilling rig
Friday, May 12, 2023
Researchers at the University of Oklahoma recently unveiled a drilling rig that could tap into geothermal vents below the surface of the earth and provide a source of energy that was previously inaccessible, according to Interesting Engineering.
Geothermal energy, if it can be accessed, could be a reliable source of power without any carbon emissions. However, a viable way to tap into the source at depths twice as deep as our deepest oil and gas wells has yet to be fully tested and utilized.
Orkhan Khankishiyev, a master’s student at the University of Oklahoma, has conceptualized a rig that is 17 feet tall and may have the ability to reach the depths necessary — at least 20,000 feet deep — to tap into geothermal energy.
While the team has moved from concept to prototype quickly, it could take a couple of years to extensively test its performance.

Shale FAQ
What is fracking?
Fracking is a slang term for hydraulic fracturing. Fracturing is a process by which highly pressurized fluid is pumped thousands of feet into the ground to fracture rock formations. The goal is to release the natural gas that’s locked inside the rock.
Is it safe?
What most concerns people about fracturing is ground water contamination. The worry is that fractures underground, caused by the process, will extending upwards and into aquifers, releasing gas and chemicals into the ground water supply. There’s been no confirmed reports of such a thing happening. Though surface spills and drill site blowouts can lead to localized environmental concerns.
Will my water catch on fire?
Flammable water is caused by the release of methane gas into a drinking water supply. Methane gas occurs naturally and can be released by any kind of drilling, including water wells. In Pennsylvania officials fined Chesapeake Energy $1 million for contaminating ground water with methane. It was determined that the company had not properly cemented it’s boreholes and gas migrated up the well, between rock and into aquifers.
