Attaining the proper values of main production parameters of operating geothermal installation: outflow, temperature, water level in production well and required injection pressure in a well for reinjection may significantly reduce the costs of energy production. Lower production costs compensate high investment expenditures and reduce the energy prices down to an acceptable level, competitive in relation to conventional energy sources. In the research project, we used the TOUGH2 simulator to select configuration of geothermal doublet and to estimate the discharge of potential geothermal installation localized in the vicinity of Kalisz and based upon the existing Zakrzyn IG-1 well. Considering the measurements and other information gained during the drilling operations, the conceptual model was generated. In order to select the optimal configuration of the doublet, which would ensure the maximum yield, the analysis was carried out on the influence of production/injection wells spacing on production parameters. The optimization aimed to determine the minimum spacing which would guarantee that the injection well would not affect the temperature of fluid discharged from the production well within the presumed circulation time.
