Overcoming challenges in the classification of deep geothermal potential [PDF]

, 2015
The geothermal community lacks a universal definition of deep geothermal systems. A minimum depth of 400 m is often assumed, with a further sub-classification into middle-deep geothermal systems for reservoirs found between 400 and 1000 m.
