Abstract
A natural geothermal reservoir is an aquifer generally in liquid phase confined between two impermeable layers of rock. Drilling of such reservoirs causes a decompression which allows the in- situ vaporization of some water and the development of a dual-phase flow.
Dual-phase flow is directed by the fractures of the reservoir; energy extinction is mainly determined by heat and mass transfers between the rock and the fluids. A large part of the energy stored in the r e servoir is the heat of the rock, so the knowledge of these two interconnected mechanisms is very important to appreciate the behavior of geothermal reservoirs.
