MEASUREMENT OF FORMATION GAS PRESSURE IN CASED WELLBORES USING PULSED NEUTRON INSTRUMENTATION

MEASUREMENT OF FORMATION GAS PRESSURE IN CASED WELLBORES USING PULSED NEUTRON INSTRUMENTATION

A pulsed neutron tool with three or more detectors is used for making measurements inside casing. The measurements may be used to determine gas saturation at a constant gas pressure, pressure at constant gas saturation, or to determine both gas saturation and gas pressure.
