Abstract:
Borehole logging methods for estimating a parameter of interest using nuclear radiation. Methods include estimating a water saturation of the formation from gamma radiation from at least the formation detected in the borehole using a radiation detector, the gamma radiation responsive to a pulsed neutron source and resulting from at least one of: (i) decay of nitrogen-16 formed by activation of oxygen-16, and ii) inelastic scattering of neutrons from oxygen. This may include using at least one processor to: obtain a gamma ray count measurement, representing gamma rays from one of: (i) the decay of nitrogen-16 (ii) and the inelastic scattering, and estimate the water saturation using the gamma ray count measurement and a model comprising a relationship between measured gamma ray counts and modeled gamma ray counts from each of a fully water saturated formation and a minimally water saturated formation.

Claim (Index 8):
A method for estimating at least one parameter of interest of a formation, comprising:\n conveying a carrier in a borehole intersecting the formation at a logging speed of at least 10 feet per minute, the carrier having disposed thereon a pulsed neutron source and a radiation detector; activating the pulsed neutron source; detecting gamma radiation in the borehole from at least the formation, the gamma radiation responsive to the pulsed neutron source and resulting from at least one of: (i) decay of nitrogen-16 formed by activation of oxygen-16, and ii) inelastic scattering of neutrons from oxygen; estimating, by an information processing device including at least one processor and a processor memory for executing programmed instructions, a parameter of interest of the formation from the gamma radiation by using at least one processor to:\n obtain an oxygen estimate comprising an estimate of elemental content of the formation for oxygen using a spectrum of the detected radiation; and \n estimate the at least one parameter of interest using at least a formation lithology and the oxygen estimate, wherein the oxygen estimate is the sole estimate of elemental content of the formation used in estimating the at least one parameter of interest, and wherein the formation lithology is at least a characterization of a combination of minerals in the formation, and at least one of the minerals contains oxygen.
