Mannvit Engineering Locates Geothermal Heat Near Miskolc in Hungary

Share Article

Geothermal Resources Discovered by Mannvit Engineering in Miskolc, Hungary have Higher Flow Rates and Higher Temperature than Expected. Upon Completion of a New Heating Utility in Miskolc, the Resource will Provide Heat for up to 15,000 People. This Follows the Discovery of Resources in Szentlörinc and Establishment of the Szentlörinc Heating Utility Earlier this Summer.

Drilling near Miskolc Hungary confirmed a geothermal resource, as predicted by tests and analysis by Mannvit Engineering. For the past few years, Mannvit has been working on geothermal development projects in Hungary as a consultant for the Hungarian energy company, Pannergy. Drilling began near Miskolc last spring and last week hot water was discovered at roughly 2 kilometer depth.

First short-term well tests suggest that the well may supply approximately 70 to 90 l/sec. of 115°C hot water, revealing higher flow rates and geothermal resource temperatures higher than expected. This indicates that the area may deliver more geothermal energy than first anticipated. Further tests will be conducted in order to verify the initial results. Mannvit Engineering's role in the discovery included interpretation and evaluation of geoscience data for the borehole site selection, the borehole design and supervision of the drilling operation. Mannvit will continue to evaluate the drilling and well testing results in parallel to the development of further drilling plans for Miskolc.

Miskolc in East Hungary is one of the largest cities in Hungary with approximately 200,000 inhabitants. Pannergy's plans include construction of a heating utility that would serve up to 15,000 people. This is the second geothermal resource discovered by Mannvit, as a Pannergy consultant, following last fall's identification and testing of hot water resource near the town Szentlörinc in South West Hungary.

Continued development in Szentlörinc includes the establishment of the Szentlörinc Heating Utility this summer. The utility was formally established and the cornerstone laid by Mr. Össur Skarphéðinsson - Icelandic Minister for Foreign Affairs and External Trade, Pál Kovács - Deputy Secretary of Department of International Development of Hungary and Márk GyQrvári - Mayor of Szentlörinc. The utility, designed by Mannvit for Pannergy, will be the largest renewable and environmental friendly energy utility in Hungary, and will reduce the burden on current gas heating utilities.

Mannvit's Hungarian operations are based in an office in Budapest, established in 2008 to support projects in Central-Europe. Mannvit's work in Hungary includes working with a large network of companies with a rich local knowledge-base, including drilling knowledge based on experience drilling for water, oil and gas. As well as working on projects in Hungary, the office is already supporting projects in Germany, Slovakia, Slovenia, Bosnia-Hersegovina, Romania, Greece and Turkey.
