Elemental concentrations from gamma ray spectroscopy logs

Description
A set of gamma-ray spectrometers have been combined in a single tool string to routinely obtain elemental concentrations for ten formation elements in a single logging run. The key to obtaining the elemental concentrations for the set of significant elements is a new technique for combining logging measurements using different types of nuclear reactions through a model based on both nuclear physics and geochemistry. The model has been validated by comparisons between logging and core analysis results for numerous wells. (author). 13 refs, 5 figs, 3 tabs
