WRRCTMR No.10 Electric Well Logging on Oahu

Abstract

The Water Resources Research Center has begun an investigation of the uses of electric well-logging in Hawaiian hydrogeologic conditions. Since the arrival of the electric well logger in April, 1966, 32 producing wells and test wells plus 2 small diameter test holes have been surveyed on Oahu. The correlation between the interpretation of electric logs made on sediments and actual drilling cores is excellent. Electric logs obtained on wells in basalt generally display good electric contrasts but their interpretation is more difficult than is the case with the logs in sediments.
