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 15):
A method for estimating at least one parameter of interest of a formation, comprising:\n conveying a carrier in a borehole intersecting the formation, the carrier having disposed thereon at least one energy source and at least one nuclear radiation detector; activating a volume of interest in a formation with the at least one energy source; acquiring nuclear radiation information using the at least one nuclear radiation detector in the borehole; estimating the at least one parameter of interest by using at least one processor to separate the nuclear radiation information into a plurality of nuclear radiation components each representing nuclear radiation from a corresponding different daughter radionuclide using a model relating each nuclear radiation component to an estimated nuclear density of the corresponding parent nuclide; and performing at least one of: i) conducting further operations in the earth formation in dependence upon the parameter of interest, and ii) displaying the parameter of interest on a display; wherein the at least one parameter of interest is at least one of: (i) a silicon content, (ii) an oxygen content, (iii) a sodium content, and (iv) an iodine content, and (v) an iron content, (vi) an aluminum content, and (vii) a magnesium content;
