  • Publication number: 20180003525
    Abstract: A linear measurement device may be formed from a first tube axially translatable with respect to a second tube. Inside the first tube may be placed a sensor capable of sensing a magnetic field. A magnet may also be found within the first tube and produce a magnetic field sensible by the sensor. The second tube may comprise a plurality of deviations disposed therealong capable of altering the magnetic field when near the magnet. As the first tube is axially translated with respect to the second tube, the sensor may sense alterations in the magnetic field due to the plurality of deviations thus allowing for a linear displacement to be determined.

  • Publication number: 20170016290
    Abstract: A flow diverter including a bypass element to divert at least a first portion of drilling fluid from a drill string to the borehole annulus. The first portion of fluid, or bypass flow, may be provided to the borehole annulus to clear cuttings generated by a drill bit of a BHA. The remaining fluid flow, or BHA flow, may be expelled through the bottom of the BHA. The fluid discharged through the BHA may enter the annulus and flow upward with the fluid flow diverted through the flow diverter to aid in clearing cuttings. The flow diverter also includes a choke housing disposed concentrically within a drill collar and containing a plurality of chokes to regulate bypass flow. An actuation system may be coupled to the flow diverter to control opening/closing of the chokes and to measure flow rate of the first portion of fluid and/or the remaining fluid.

  • Patent number: 7967083
    Abstract: A drill string having a drill bit with a bit body located between a shank and a working face. The working face has at least one cutting element and a jack element disposed partially within the drill bit body and partially protruding from the working face. The jack element is adapted to be rotated with respect to the bit body by a driving mechanism disposed within a bore of the drill string. A generator or motor with a rotor is incorporated into a torque transmitting mechanism that links the driving mechanism to the jack element, and configured so that at least one waveform is produced in the generator or motor when the jack element is rotated. The waveform is processed by an electronic processing device to determine the rotational position of the jack element.

  • Patent number: 7504963
    Abstract: A system for transmitting power to components of a downhole drill string is disclosed in one embodiment of the invention as including a power source providing an alternating current at a first frequency. A rectifier is provided to convert the alternating current to direct current. An inverter converts the direct current to an alternating current at a second frequency, different from the first frequency, and more efficient for power transmission. An inductive coupler converts the alternating current at the second frequency to an alternating magnetic flux for transmission across a tool joint of a downhole drill string. The magnetic flux may be detected by another inductive coupler, magnetically coupled to the first inductive coupler, to convert the alternating magnetic flux back to an alternating current at the second frequency.
