Classification of Schlumberger Resistivity Sounding Curves in Geothermal Field

Abstract

The classification of Schlumberger resistivity sounding curves in various geothermal fields is treated in the application of a multiple layer resistivity problem. In comparison of the result of interpretation of resistivity sounding curves with near exploratory or production wells, it is demonstrated that only some type curves, which are satisfied by geothermal requirement, indicate the existence of geothermal reservoir. As a result, the distribution map of type curves in Kirishima geothermal field is presented as a basic data to determine the drilling target. Finally the result of interpretation of Schlumberger resistivity sounding curve observed at the station of I-23 is correlated with the drilling logs of the exploratory well KT-4.
