High temperature spectral gamma well logging

Technical Report ·
DOI:https://doi.org/10.2172/527429· OSTI ID:527429

A high temperature spectral gamma tool has been designed and built for use in small-diameter geothermal exploration wells. Several engineering judgments are discussed regarding operating parameters, well model selection, and signal processing. An actual well log at elevated temperatures is given with spectral gamma reading showing repeatability.
