Abstract
Improved vertical resolution from pulse neutron logs is obtained by the disclosed process; a pulse of fast neutrons is emitted from a source and counts are taken at near and far dectors. This is done repetitively so that the interval between neutron bursts is conveniently divided into a number of gates, the preferred form being six contiguous gates. The count rate especially in gates 3-6 is obtained and is processed in a modified form to thereby enhance vertical resolution. While before vertical resolution was dependent in part in spacing of the detectors and source, improved vertical resolution is obtained to thereby locate thin beds which would otherwise be obscured.
