Report on annual temperature surveys in Well KS-4

Abstract

Downhole temperature surveys were run in Well KS-4 in June 1996 in partial fulfillment of the requirements for annual mechanical integrity tests under the UIC permit and PGV's Casing Monitoring Program. In accordance with PGV's normal procedure, one survey was run with the well on injection, and two were run after shut-in to measure the transient temperature response. The results exhibit a completely normal temperature recovery, with no indication of any casing leak or any interzonal communication behind casing. With concurrence from Hawaii Department of Health, Safe Drinking Water Branch, PGV scheduled these temperature surveys in KS-4 to coincide with a planned plant outage. The annual casing pressure test will be performed later in the year, in conformance to the normal schedule.
