Abstract

A newly introduced Thermal Multigate Decay’ logging system utilizes a pulsed neutron generator and two scintillation gamma ray detectors to measure thermal neutron capture cross section (E) and porosity (0) of downhole formations. Capture gamma rays between neutron bursts are measured in each detector in six time gates; background is also measured and subtracted.
