  1. Development of Polish Geothermics and Heat Flow data relationship. Marta Wróblewska, Jan Szewczyk ENGINE, Launching Conference, Orlean 12-15 February 2006

  2. 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

  3. 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

  4. 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.

  5. Depth interval of HFD estimation Gosnold,2005

  6. Heat Flow Density of Poland (2005) Stargard Pyrzyce 160 – 190 oC / 5km Uniejów Mszczonów Słomniki Podhale

  7. Bottom Hole Temperatures BHT Depth [m] Temperature

  8. Geothermal plants & temperatures at 2 km depth T oC

  9. Geothermal plants 2006 Currently starting Jurrasic, sandstone 2001 Cretaceous, sandstone 60oC, Mo ~ 5 g/l 1999 Cretaceous,sandstone 40oC, Mo~ 0,5 g/l 1996 Jurassic,sandstone 61oC, Mo ~120 g/l 2001 Cretaceous,sandstone 17oC, Mo ~ 0,4 g/l 1992/3 Triassic, limestone dolomite 82- 86oC, Mo<3 g/l

  10. Geothermal energy in Poland (2004) * including 23,56 MWt i 74,4 TJ/r from absorbing heating pumps Kępińska B., (presented on WGC Turcja 2005)

  11. 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
