  • Pulsed neutron tool for downhole oil typing
    Patent number: 9389335
    Abstract: Methods for determining a value indicative of liquid density of a formation include obtaining an inelastic count rate and a capture count rate of a gamma detector for a particular borehole depth, calculating a ratio of an inelastic count rate to a capture count rate for the particular borehole depth, determining a value indicative of liquid density based on the ratio of the inelastic count rate to the capture count rate for the particular borehole depth, repeating the obtaining, calculating and determining for a plurality of borehole depths, and producing a plot of the value indicative of liquid density of the formation as a function of borehole depth.
    Type: Grant
    Filed: May 17, 2013
    Date of Patent: July 12, 2016
    Assignee: Halliburton Energy Services, Inc.
    Inventors: Larry Jacobson, Weijun Guo

  • Pulsed-Neutron Formation Density
    Publication number: 20060284066
    Abstract: A method and related system of determining formation density by compensating actual inelastic gamma rays detected from a pulsed-neutron tool for the effects of neutron transport. The method and systems may model response of the tool and use the modeled response as an indication of an amount to compensate detected inelastic gamma rays.
