Possible simultaneous heat extraction from geothermal reservoirs at various depths in East Hungary, a case study of Létavértes

Abstract

Increasing geothermal energy production is to be accomplished by the extraction from all aquifers simultaneously. If there is need for local energy sources, by adequate planning such individual complex systems can constitute the basis of a subregion’s energy supply. Certain systems can lead to local overproduction since many of them aim to exploit from the same depth. As a result, extractable power lags behind the planned value. If extraction is carried out from different depths interference may occur, however, to a far less extent. The purpose of the paper is to quantify the total available geothermal power of a specific area in East Hungary from each depth considering the local natural and regulatory environments. The conditions presented characterize east Hungary in general, only the depths of the reservoirs are different. Therefore the applied technologies are the same only the produced heat powers differ slightly.
