NEDO has been conducting a research project titled {open_quotes}Deep-Seated Geothermal Resources Survey{close_quotes} since 1992. Drilling of a deep drillhole, WD-1a, reached a depth of 3,729 in July 1995. However, WD-1a did not encounter large lost circulation near the boundary of Quaternary granite. In order to hit deep reservoirs which are expected to exist near the boundary of the granite, side-track well, WD-1b, was drilled. WD-1b encountered large lost circulations near the boundary of the granite. Side-track drilling was terminated at a depth of 2,963 m in January 1997.
