On September 14^th drilling operations near Miskolc, Hungary confirmed a geothermal resource as predicted in tests and analysis done by Mannvit Engineering. The drilling began last spring but it was not until last week that hot water was discovered at a depth of approximately 2 kilometers. For the past few years, Mannvit has been working on geothermal development projects in Hungary as a consultant for the Hungarian energy company, Pannergy.  

The first short-term 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 than expected. This indicates that the area may be capable of delivering more geothermal energy than first anticipated, however further testing must be done to verify these initial results. Mannvit Engineering’s role in this 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 these drilling and well testing results while developing 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 to utilize this geothermal resource include the construction of a heating utility that would serve up to 15,000 Miskolc residents. 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.
