Integrated MT/Gravity geothermal exploration in Hungary: A success story

Abstract

Hungary is promising for utilization of low temperature (< 150°C) geothermal energy because of its high thermal gradient, reaching almost 50° C/km over most of the country. This high gradient is mainly caused by a relatively thin layer of the Earth?s crust in that area and partly due to the non permeable lower Pannonian sediment layer that covers a large part of the country. Our geothermal evaluation project in Hungary has, since 2007, yielded over 30 possible well sites for geothermal energy production and utilization. The first drilled well was recently successful.
