A typical difference between a geothermal and an oil well is the completion downhole. An oil well has a blank steel pipe cemented into the reservoir. After installing the completion holes are created right in the target layer. A geothermal well has a wire wrapped screen hanging without support in an open hole.
In a test the typical geothermal well completion has been simulated on surface and tested.
