Abstract

Nuclear methods based on neutron and gamma-ray detection have been used for decades in the well-logging industry, including both oil and gas logging, for characterization purposes. Current well-logging tools operate in the range of 150 to 175°C. For geothermal logging applications, however, operations at higher temperatures are needed. In this paper, the results for neutron and photon detector measurements at higher temperatures, environmental tests, and modeling and simulations are presented.
