  • Publication number: 20200174150
    Abstract: A system for performing downhole logging operations includes a power supply for providing a current and a conductor coil electrically coupled to receive the current from the power supply. The system further includes a switch electrically coupled to the power supply for controlling current provided to the conductor coil and enabling a pulse of current to be supplied to the conductor coil for an “on” duration and turning off current provided to the conductor coil for an “off” duration after the “on” duration, in which the “off” duration lasts longer than the “on” duration. The system also includes a permanent magnet coupled to the conductor coil. The conductor coil receives the pulse of current from the power supply during the “on” duration and not receiving current during the “off” duration. The pulse of current causes the permanent magnet to reverse polarity and generate a transient magnetic field.

  • Patent number: 10520641
    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.

  • Patent number: 8299797
    Abstract: A method and apparatus for evaluating an earth formation penetrated by a borehole comprises taking resistivity measurements using a plurality of resistivity arrays or pads positioned within the borehole proximal the borehole wall. In one embodiment, pads are spaced apart azimuthally around the perimeter of a tool body, each pad carrying at least one electrode thereon. A sequence of resistivity measurement operations are performed involving sequentially operating each pad, in turn, as a transmitter, with remaining pads and electrodes operated as return electrodes. The sequence preferably involves a succession of adjacent pads around the perimeter of the tool body, resulting in a full rotational (360°) imaging of the formation penetrated by the borehole. In one embodiment, the pads include at least two electrodes spaced vertically apart from one another, such that helical current paths are defined between transmitting electrodes and return electrodes.
