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.
