Sažetak
Geothermal reservoir Rečica was discovered with two wells: Ka-2 and Ka-3. Based on the results of investigations from abovementioned wells, the reservoir temperature of 140 Celsius degrees was determined. Ka-3 would be production well and Ka-2 injection well. Depth interval from 1 900 to 3 523 meters is designed for hot water production in Ka- 3 well and depth interval from 3 200 to 4 145 meters is designed for injection of chilled water in Ka-2 well. Gradual utilization of reservoir heat energy can be planned by, applying Clausius- Rankin process. In view of total efficiency factor, energy output of geothermal source should be expressed as maximum useful work or exergy where reversible processes lead working fluid into mechanical and thermal environment conditions equilibrium. Chilled geothermal water would be returned through injection well to the same reservoir what assures heating reproducibility and pressure maintenance in the reservoir. Economic analysis estimated total investment costs needed for development of geothermal power plant, and economic indicators of profitability of geothermal project. The production of electricity from Rečica reservoir would be economically viabl
