Heat Flow Density
HFD estimation errors
•Logging error caused by non equilibrium state
•Different methods of calculation
•Different depth interval taking for calculation
HFD mapping error
•Random scatter data for mapping
•Different approaches of HFD calculation in
one image
HFD data
HFD evaluated on base of
lab data of thermal conductivity
HFD value with using of
thermal conductivity model
Different authors
published data of HFD value
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.

Summary
• 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 results it is 40 – 110 mW/m2 that still concludes
low enthalpy resources classification
• For last few year the growing interest in geothermic is observed in Poland,
and local authorities requires a clear answer for its opportunities
