Abstract: Methods of evaluating a parameter of interest of a formation intersected by a borehole, including exposing a radiation sensor in the borehole to a calibration radiation source while a measurement operation using the radiation sensor is suspended. Methods may include exposing the radiation sensor to the calibration radiation source when the radiation sensor is stationary relative to the formation or during interruption of drilling operations or at predetermined intervals; processing response information, including performing a mitigation process on a portion of the response information relating to exposure of the radiation sensor to a calibration radiation source during measurement operations; or using the calibrated measurement information to estimate parameters of interest. Devices may include a radiation sensor, a calibrator including a calibration radiation source, and an actuator configured to intermittently expose the radiation sensor to the calibration radiation source. The radiation sensor may be a spectral gamma ray detector.

Abstract: A method of identifying barite in a subterranean annulus that surrounds a wellbore, where the method includes detecting gamma rays in the wellbore that are generated from the annulus, obtaining a count rate of the detected gamma rays, comparing the count rate with reference data, and determining the presence of barite in the wellbore based on the comparison. The count rate can be a ratio of counts of detected gamma rays obtained from spaced apart receivers on a downhole tool, or a ratio of detected inelastic and capture gamma rays. The reference data is obtained by using a simulation algorithm.

Abstract: Methods, systems, devices, and products for estimating at least one parameter of interest of a volume of interest of an earth formation using nuclear radiation based measurements. Logging tools include a limited aperture collimated radiation beam source, detectors, and at least one processor configured to take measurements. The source is configured to emit a beam of radiation radially from the logging tool into an elongated volume of interest outside the wellbore such that the beam penetrates a plurality of zones of the volume of interest. Each zone represents a range of radial depths corresponding to a respective infrastructure component associated with the wellbore, such as nested tubulars. Each detector has a unique angle of detection and is configured to generate measurement information in response to spatially coherent backscattered gamma rays. Each detector is associated with scattering events at one of the plurality of zones.

Abstract: Estimating parameters of interest of a formation, including density, porosity, and fluid saturation. Methods relate to gamma ray energy spectra calibration for a radiation detector including generating a calibration radiation spectrum using measurements of radiation with the detector in a time interval wherein the radiation comprises predominantly gamma rays emitted by decay of radionuclides produced by neutron activation reactions resulting from neutron irradiation, the time interval following a prior time interval corresponding to thermal neutrons produced from the irradiation; making at least one other radiation measurement with the detector outside the time interval; and producing a calibrated radiation measurement from the at least one other radiation measurement using the calibration radiation spectrum. The measurements may be taken in the time interval by conveying the radiation detector in the borehole at high speed and using a background gate of the detector.

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.
