Medhat W Mickael: Method for determining thermal neutron capture cross-section of earth formations using measurement from multiple capture gamma ray detectors. Western Atlas International, Richard A Madan Mossman & Sriram Fagin, May 16, 2000: US06064063 (8 worldwide citation)

A method for determining the thermal neutron capture cross-section of an earth formation penetrated by a wellbore from counts of capture gamma rays. The capture gamma rays are detected at spaced apart locations after bombarding the formations with high energy neutrons. The method includes determinin ...
