I was wondering how feasible it would be to reuse abandoned oil pumps for geothermal energy. A closed loop system [1] would probably be the most appropriate, with energy generation by spinning of a turbine by steam that gets recycled. I don't have the expertise and was wondering if someone can share a bit of knowledge with the rest of us.

I don't have knowledge, but my understanding based on a conversation I had on the topic with a friend of mine is that the "let's use hydraulic fracturing to make geothermal energy feasible in North America" idea involves drilling very far down. Oil is on [average][1] about a mile down, while [one of Fervo's wells][2] is three times deeper.
