As shown in Table 1, four wells have been used for circulation tests at Hijiori. The diameters of all the open-hole sections of the wells are 8-{1/2} inches. SKG-2 is an injection well. An 1800 m deep reservoir was stimulated hydraulically by water injection into the open-hole section of SKG-2 in 1986. HDR-1 is also an injection well. A 2200 m deep reservoir was stimulated by water injection into the open-hole section of HDR-1 in 1992. HDR-2a and HDR-3 are used to produce steam and hot water from both reservoirs. The subsurface system was created In granodiorite basement rock with temperatures of 250 {degrees}C at a depth of 2,500 m and 270{degrees} C at depth of 2,700 m.
