The Hydrogeothermal Model of Macva

Abstract

Macva is an agricultural region of about 800 square kilometers in surface area about 80 kilometers west of Belgrade. Geologically, it is on the southern margin of the Pannonian Basin. Geothermal anomalies in Neogene sediments and previous hydrogeothermal investigations indicate thermal waterbearing Triassic limestone beneath Neogene sediments throughout the whole Macva region. The highest measured temperature is 78 oC at a depth of 610 meters in Triassic limestone. The highest temperature expected in the aquifer on the basis of hydrochemical geothermometers, is about 100-110 oC. Natural conditions in Macva are favorable for intensive exploitation of geothermal energy. Based on the local geology, hydrogeological and hydrothermal characteristics, the calculated thermal power potential of the Macva region is approximately 150 MWt.
