  • Determination of elemental concentrations from the capture and inelastic energy spectra
    Patent number: 11243328
    Abstract: Methods and systems for determining the elemental composition of formation rock are disclosed. The systems include a pulsed-neutron geochemical logging tool that is conveyed in a borehole traversing the formation. The pulsed-neutron geochemical logging tool can collect inelastic and capture neutron spectra. The inelastic and capture spectra are processed to provide the elemental composition of formation rock after removing contributions due to elements in the borehole and in the pores of the formation.
    Type: Grant
    Filed: September 24, 2018
    Date of Patent: February 8, 2022
    Assignee: Weatherford Technology Holdings, LLC
    Inventors: Richard R. Pemper, Guojing Hou
