We do use conventional drilling for geothermal!

We just have to be more selective with the location to ensure that there is heat nearer the surface. They're right, if you drill deep enough, it's hot everywhere. Even in non-geothermal oil and gas wells, we commonly have temperatures that exceed 250 degrees Fahrenheit. Our tools that we send down whole are commonly rated for 300-350 degree temperatures. Plenty of temperature down there!

Although I admit, I'm an oil and gas guy and don't really have any industry knowledge of geothermal.
