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):
An apparatus for estimating at least one parameter of interest of a formation, comprising:\n a carrier configured for conveyance in a borehole in the formation; at least one energy source operably connected to the carrier and configured to activate a volume of interest in the formation; at least one nuclear radiation detector disposed on the carrier and configured to generate information representative of nuclear radiation from an activated volume of interest; and an information processing device configured to estimate the at least one parameter of interest by separating the generated 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, wherein the generated nuclear radiation information is obtained while the carrier is conveyed in the borehole at a logging speed of at least 10 feet per minute; 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.
