Development of Polish Geothermics and Heat Flow data relationship. Marta Wróblewska, Jan Szewczyk ENGINE, Launching Conference, Orlean February 2006

Heat Flow Density HFD estimation errors Logging error caused by non equlibrium state Different methods of calculation Different depth interval taking for calculation HFD mapping error Random scatter data for maping Differeent approaches of HFD calculation in one image

HFD data Different authors published data of HFD value HFD evaluated on base of lab data of thermal conducivity HFD value with using of thermal conductivity model

Paleoclimate effect The observed vertical variations of HFD in shallow part of profiles are mainly due to Holocene warming. The lower part of profiles are still in thermal regime of the Weichselian glatciation.

Unification of European HFD estimation method is required and shallow holes data should be recalculated Heat Flow in Poland includes in range 40 – 90 mW/m2 and according to the new resulst it is 40 – 110 mW/m2 that still concludes low enthalpy resources classification For last few year the growing interest in geotermics is observed in Poland, and local authorities requires a clear answer for its opportunities Summary
