Abstract
This paper presents a simple, statistical technique of estimating average geothermal water salinity from any section of a well. The method is based on crossplotting resistivity data from shallow and induction well logs, the slope of the crossplot being proportional to the formation water salinity. Examples are given from several sections of the well RRGE#1 at the Raft River geothermal field. The salinities estimated for these zones agree well with the salinity measured from the produced water.
