Abstract: A method to offer insight on reservoir compartmentalization through the automation of single- and multi-well formation pressure analysis. The method specifically accounts for the measurement uncertainty and any prior information about the reservoir to draw evidence on at least one of a fluid type, a locating feature of the at least one fluid body, vertical compartmentalization, and lateral compartmentalization.

Abstract: A system includes a neutron source that emits neutrons. The system also includes a vessel that holds a lithium-containing material including a lithium-sorbent material and a lithium-containing brine. Further, the system includes a neutron detector that receives a subset of the neutrons emitted from the neutron source that are transmitted through the lithium-sorbent material and the lithium-containing brine. The neutron detector also determines a concentration of lithium based on the received subset of neutrons.

Abstract: An earth formation traversed by a borehole is investigated. A borehole tool having a neutron source and a photon detector is located in the borehole and used to obtain photon scatter information in or about the borehole. A chemical element located in a region in or about the borehole is quantified by using the photon scatter information and at least two different spectral standards for that element.

Abstract: Elemental concentrations in subterranean formations may be determined using neutron spectroscopy. For example, neutrons may be emitted by a downhole tool into the formation and produce gamma rays via inelastic scattering of fast neutrons or capture of slow neutrons. The borehole surrounding a downhole tool may introduce artifacts in the neutron spectroscopy measurement. Embodiments of the present disclosure are directed to techniques that reduce artifacts signals in downhole tools that include one or multiple detectors based at least in part on the inelastic and capture measurements.

Abstract: Composition-matched downhole tools and methods for using such tools are provided. One such method includes emitting neutrons using a neutron source in the downhole tool to generate formation gamma rays in a surrounding formation. At the same time, however, some of the neutrons may interact with different parts of the downhole tool to form tool gamma rays. The gamma ray spectra of at least some of the formation gamma rays and the tool gamma rays may be detected using a gamma ray detector. The tool gamma rays from the different parts of the tool may have a substantially similar spectral shape. As such, a processor may be used to analyze the spectra of the tool gamma rays using a single tool background standard, thereby simplifying the analysis and improving the precision of the results.

Abstract: Systems and method presented herein enable the estimation of porosity using neutron-induced gamma ray spectroscopy. For example, the systems and methods presented herein include receiving, via a control and data acquisition system, data relating to energy spectra of gamma rays captured by one or more gamma ray detectors of a neutron-induced gamma ray spectroscopy logging tool. The method also includes deriving, via the control and data acquisition system, one or more spectral yields relating to one or more elemental components from the data relating to the energy spectra of the gamma rays. The method further includes estimating, via the control and data acquisition system, a measurement of porosity based on the one or more spectral yields relating to the one or more elemental components.

Abstract: Systems and methods are provided for distinguishing between elements located at different distances from a radiation detector used in neutron-induced gamma-ray spectroscopy using a Doppler effect. A pulsed neutron generator may emit neutrons out of a downhole tool in a geological formation at an energy level high enough to cause inelastic scattering with nuclei of an element to generate gamma-rays. A gamma-ray detector may detect the energy levels of the gamma-rays, in the reference frame of the detector, and data processing circuitry takes the detected spectrum of gamma-rays and distinguishes spectra of gamma-ray energy levels for nuclei of the element located nearer to or farther from the detector based at least in part on the Doppler shift of the energy levels of respective gamma-rays.
