Abstract
Five cross sections were applied as a result of MT method investigations in addition to the results of conventional analyses at the Kakkonda geothermal area; three-dimensional resistivity distribution was made into a database by using the Kriging method which makes a matching with anisotropy of seismic center distribution in micro-earthquakes; and the database was compared with the data derived from surveys on the pilot survey well WD-1a and the side-truck well WD-1b thereof. As a result, it was found that the well WD 1b which encountered a water loss zone had the water loss zone exist in a region with relatively lower resistivity than in the well WD-1a which did not encounter a water loss zone. The region in which the water loss zone was encountered existed in a very steep slope region going from the high resistivity region in the west side toward the low resistivity region in the east side. This fact suggests a possibility that fractures have developed in this region with sharp slope in the resistivity in this area. Adding three-dimensional complementary function to the GEOBASE database by using a simple Kriging allowed the direction of anisotropy in spatial data to be freely and quickly decided.
