Engineering evaluation of geothermal reservoirs

Reservoir engineering evaluation of geothermal systems attempts to provide answers on the extent of the reserves, their probable longevity and the deliverability and production rate of the reservoir. Economic decisions on the desirability of the exploitation of the particular reservoir hinge on these findings. This paper presents a set of calculational procedure and thinking sequences available to the geothermal reservoir engineer that would aid in an appropriate management decision. An exploitable geothermal system consists of a fluid as well as a heat reservoir. Since much of the heat is stored in the confining rock, reinjection strategies are outlines for the efficient mining of heat.
