Computer Simulation of Low Enthalpy Geothermal Reservoirs

Abstract

Geothermal reservoir modelling is a technology that has become standard over the past decade in Eastern Europe. If sufficient information on the field is available then it is often possible to construct numerical models of the reservoir and use these models to simulate field performance under a variety of conditions. Perhaps the most important, and most challenging part of this process is the integration of information gathered by all the geo-scientific disciplines leading to the development of the conceptual model. The success of any reservoir modelling exercise is dependent upon the flow of high quality information from the basic data collection phase, through the conceptual modelling phase, to the simulation process. The paper reveals the particularities of numerical simulation of geothermal reservoirs nestled in the Pannonian Basin using modern reservoir engineering tools. There are summarised the modelling results of several types of geothermal reservoirs focusing on the general procedures adopted for model development; calibration, and production simulation forecasts.
