| Abstract | Heat extraction from the Ogachi geothermal resource has been carried out in four test periods following creation of the two-layered stimulated HDR reservoir at depths of about 720 and 1000 m. The tests consist of a 20-day hydraulic communication test in 1993, a 151-day circulation test in 1994, a 3O-day test in 1995, and l0-days of production in the summer testing of 1997. The heat extracted from each of these tests has been calculated and the cumulated heat extracted has been estimated in relation to the estimated total heat content of the reservoir. |
