| Abstract | The Warsaw synclinorium is a part of a large sedimentary structure named after the Middle Poland depression. Geothermal plant with well MszczonÛw IG-1 is situated in the central part of this synclinorium. The waters that occur in the Low Cretaceous aquifer have been exploited for central heating and domestic hot water purposes since winter of 2000, as a single well system. First preliminary numerical model of exploitation was developed in 2000. Reservoir response during three years of production is analyzed in this paper. Numerical model was set up using the simulation code Tough2. New model respects well logging data and system parameters recorded during exploitation period. Future development is simulated on the basis of previous experiences. Because the production parameters have been stabilized since the first period of exploitation, the future production can be increased depending on the heat demand. |
