| Abstract |
For Japanese geothermal developers of private companies, some conventional logs, such as temperature log, SP log and resistivity log, are available in geothermal fields. On the other hand, improvement is being made in well logging techniques on geothermal wells in the "National Sunshine Project." purpose of this paper is (1) to explain the high temperature well logging developed on the Sunshine Project, and (2) to present algorithm which can estimate porosity distributions and detect fractured zones from conventional geothermal well logging. |
