High-Temperature Well Logging Instrumentation Workshop

November 13-14, 1985 – Los Alamos, New Mexico
Convener: Bert Dennis

Summary
The Earth Science Instrumentation Group at the Los Alamos National Laboratory is developing borehole logging instrumentation that can withstand downhole temperatures in excess of 300 degrees Celcius and pressures greater than 103 MPa.

The group was formed in 1973 to provide geophysical measurements supporting the Hot Dry Rock (HDR) Geothermal Project at Fenton Hill, New Mexico. The HDR Project needed high-temperature materials, components, transducers, and instrumentation for borehole logging tools for its drilling, hydraulic fracturing, and acoustic fracture-mapping programs. The purpose of this workshop was to inform interested persons from industry, government, and universities of these successful developments in high-temperature well-logging instrumentation.
