Simulation of Pressure Response Data from Geothermal Reservoirs by Lumped Parameter Models

Abstract

Detailed numerical modeling of geothermal reservoirs is time consuming, costly and requires large amounts of field data Lumped parameter modeling is in some cases a cost effective alternative. A method has been developed that tackles simulation of pressure response data by lumped models as an inverse problem and therefore requires very little time. 'Ibis method of lumped modeling has been used successfuuy to simulate. data from several low-temperature geothermal reservoirs in Iceland. The lumped simulators have been used to predict future pressure changes and they provide information on the global hydrological characteristics of the geothermal reservoirs.
