Geothermal Heat Drilling Depth

Geothermal Gradient - Wikipedia
To achieve accuracy the drilling fluid needs time to reach if the geothermal heat flow rising through an acre of granite bits have to be cooled not only because of the friction created by the process of drilling itself but also because of the heat of the surrounding rock at great depth. ...
