EARTH FORMATION SALINITY BY COMPARISON OF INELASTIC AND CAPTURE GAMMA RAY SPECTRA

摘要

EARTH FORMATION SALINITY BY COMPARISON OF INELASTIC AND CAPTURE GAMMA RAY SPECTRA (D#73,797-F) Background corrected inelastic neutron scattering gamma ray counts for selected energy regions of the gamma ray spectrum corresponding to calcium and silicon are compared with thermal neutron capture gamma ray counts for selected energy regions of the gamma ray spectrum. These data are functionally related to chlorine presence and are used to derive an estimate of the salinity of earth formations. The inelastic scattering and thermal neutron capture gamma ray data are separated from each other by the use of a pulse neutron source and time gating techniques. -I-
