Abstract
Geothermal reservoir simulation is the technique of solving the differential equations governing the flow of fluids and thermal energy in the reservoir to predict the long term consequences of energy production. It would be possible to argue that this definition does not cover all cases, for instance it is sometimes necessary to predict the flow of dissolved gases as well as the reservoir fluid, but it is a satisfactory general definition. There are two main reasons for carrying out a simulation study, as a means of resource assessment and as a means of controlling the reservoir during the production life of the field.
