High Enthalpy Geothermal Potential of the Deep Gas Fields in Central Drava Basin,Croatia

In Croatia there is an urgent need to improve energy balance with more efficient methods of energy resources exploitation. There are approximately 3,000 wells drilled on oil, gas/condensate and geothermal reservoirs, of which only 50 were primarily drilled for purpose of geothermal exploitation. Over 10,000 seismic measurements were conducted. The most of drilled wells are scheduled for permanent abandonment in the near future, because of economical reasons and technological limitations of production. However, oil and gas wells which are near the end of production might be reassigned into geothermal wells, if aquifer water temperature and flow were satisfactory.
