  • Combined radioactive source for gamma-neutron tool
    Patent number: 10209396
    Abstract: A first set of radiation detectors may be disposable on the a drill string, wherein the first set of radiation detectors are capable of detecting gamma radiation and neutron radiation; and a combined chemical source spaced from the first set of radiation detectors, wherein the combined chemical source comprises a gamma radiation emitting material and a neutron radiation emitting material. The first set of radiation detectors and combined chemical source may be used in methods for logging a wellbore.
    Type: Grant

    Date of Patent: February 19, 2019
    Assignee: Halliburton Energy Services, Inc.
    Inventors: Robert Wayne Pennison, Paul Andrew Cooper
  • Deep formation evaluation systems and methods
    Patent number: 10077637
    Abstract: Apparatuses, systems and methods for deep formation evaluations, at least some of which include LWD tool modules positioned along a drillstring with a first LWD tool module that includes a transmit antenna, a second LWD tool module that includes a receive antenna and at least one position measurement device that at least partially determines spatial locations of the transmit and receive antennas relative to each other. A formation model is then matched to a surrounding formation based at least in part on said relative spatial locations.
