DOI:https://doi.org/10.2172/6565161· OSTI ID:6565161

This Geothermal Logging Instrumentation Development Program Plan outlines a nine-year, industry-based program to develop and apply high temperature instrumentation technology which is needed by the borehole logging industry to serve the rapidly expanding geothermal market. Specifically, this program will upgrade existing materials and sondes to improve their high-temperature reliability. To achieve this goal specialized equipment such as high temperature electronics, cables and devices for measuring formation temperature, flow rate, downhole pressure, and fractures will be developed. In order to satisfy critical existing needs, the near-term (FY80) goal is for operation at or above 275/sup 0/C in pressures up to 48.3 MPa (7,000 psi). The long-term (FY84) goal is for operation up to 350/sup 0/C and 138 MPa (20,000 psi). This program plan has been prepared for the Department of Energy's Division of Geothermal Energy (DGE) and is a portion of the DGE long-range Geothermal Well Technology Program.
