Geothermal Exploration Using Integrated 2-D MT and Gravity Surveys in Hungary

摘要

All available data were used to outline the most prospective areas for geothermal electrical production and space heating in Hungary. Before locating wells to be drilled for geothermal utilization more data was needed. It was decided to use integrated MT and gravity survey in additional to the existing data in an attempt to further strengthen the possibility of drilling successful wells. Survey lines were proposed on the geosciences data and optimized for the clients concerns. The spacing for the 2-D MT lines was 1000 m, but 250 m for the gravity points. When the surveying was finished for a given line the geological cross section is derived and used for constraints on the MT and gravity interpretation.
