GAS DETECTION AND QUANTIFICATION METHOD USING A PULSED NEUTRON LOGGING TOOL.

摘要

A method of formation evaluation using a pulsed neutron tool. The approach removes the effect of formation hydrogen index (HI) from the nuclear response of the tool. It can be used for gas detection and quantification, as well as for other fluids. It can also be used to improve a formation hydrogen index (HI) measurement.
