  • Patent number: 10760378
    Abstract: An apparatus for generating pressure pulses in a fluid flowing in a downhole tool includes a stator, a rotor, a motor, and an electronics module. The stator and the rotor each have one or more flow passages. The motor oscillates the rotor relative to the stator to align and misalign the flow passage(s) of the stator and the rotor to thereby generate the pressure pulses. The electronics module drives the motor using at least a first signal and a second signal. The motor causes the rotor to have an information-transmitting oscillation in response to the first signal and a cleaning oscillation in response to the second signal.

  • Patent number: 10724348
    Abstract: Hydrocarbons are exploited within a sedimentary basin using a stratigraphic simulation coupled with a hydrologic model and a terrestrial organic matter accumulation model. The inorganic sediment distribution within the basin is determined with a stratigraphic simulator for at least one time step. Then, at least one unsaturated zone is delimited within the basin using a hydrologic model. At least one zone of terrestrial organic matter accumulation within the basin and an amount of terrestrial organic matter accumulated in this accumulation zone are determined by a model of the terrestrial organic matter accumulation as a function of the unsaturated zone thickness, of the unsaturated zone thickness stability and of the surface water flux defined for the time step considered.

  • Patent number: 10718165
    Abstract: An integral pressure relief assembly is comprised within a roller assembly of a roller reamer. The integral pressure relief assembly extends through a pair of pillow blocks and a bearing shaft of a retention assembly of the roller assembly. A volume of lubricant is inserted under pressure through a relief valve into an interior channel of the bearing shaft. A spring element in combination with an elastomeric piston provides additional pressure to the pressurized volume of lubricant contained within the integral pressure relief assembly. The lubricant absorbs heat from motion of the bearing shaft and a cutter assembly. As the lubricant increases in pressure, the relief valve releases lubricant from the bearing shaft when a sufficient differential pressure between the contained lubricant and the outside environment is achieved.
