Geothermal reservoir model of Dombóvár area, SW-Hungary

Abstract

Dombóvár is a town in the southwestern part of Hungary with a population of 19,000 people. As part of a geothermal development plan, MVM (Hungarian Power Engineering and Consulting Ltd.) is planning to change the existing heating system of Dombóvár’s industrial park into a geothermal supplied system, and possibly make the same changes to the district heating system of the entire town in the future. The goal of this study was to perform a feasibility study on the geothermal reservoir at Dombóvár to determine if it has the capacity to support a proposed geothermal well duplet. A conceptual model of the reservoir was created using available data and then a preliminary numerical model was constructed using MODFLOW. Results of the model simulations indicate that the reservoir is capable of supporting the proposed production, and therefore it is recommended to move forward with the development plan
