Development and Testing of a Single Ended Distributed Temperature Sensing System at the Beowawe, Nevada Geothermal Reservoir

Abstract: Testing of single-ended optical fibers for monitoring temperatures in geothermal production began at the Beowawe, Nevada geothermal field in June 1996. High-temperature rated polyamide-coated fibers were badly damaged within weeks in flowing wells. Optical time domain reflectometry measurements show no appreciable degradation of replacement teflon-coated and polycarbon-coated fibers after 18 and 15 months of continuous service. Comparison of the DTS temperature data with research-quality conventional temperature logs shows that considerable care must be taken in obtaining the optical fiber data if repeatable temperatures within 1 to 3F are desired. These data demonstrate that the long-term cooling trend of all three Beowawe production wells has greatly diminished or ceased entirely. To download this resource, please see the link provided.
