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

A PULSED NEUTRON TOOL (101) WITH THREE OR MORE DETECTORS (105,106,107) 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.
