The first drilling operation started in 2013 with the longest geothermal well in Europe with a 6036 m long well path. However, the productivity was significantly lower than expected and turned out as beyond any economic level. The exploitation concept followed the so-called facies concept, where a particular porous carbonate facies type is expected from 3D seismic interpretation.

Typically, the sandstone formations are encountered at very deep depths. They are the most difficult sandstone formations to drill, with rock unconfined compressive strength (UCS) of up to 35,000 psi and internal friction angles ranging from 25 to 60 degrees. These conditions make it very difficult to drill and reach optimal lateral lengths.
