  • Publication number: 20200080409
    Abstract: A system and method for optimizing drilling with a rotary steerable system may monitor downhole signals associated with vibrational loads along a drill string during drilling. A downhole controller at a rotary steerable bottom-hole adapter may generate a control indication for modifying drilling parameters of a drill bit in response to detecting harmful vibrational loads for the drill string. A modification of the drilling speed and direction of the drill bit used for drilling may be performed based on the control indication.

  • Patent number: 5939885
    Abstract: Apparatus for sensing the resistivity of geological formations surrounding a borehole includes a tubular body member (1) which is adapted to form a portion of a length of drill string. An antenna (10) is mounted within the body member (1) and the body member (1) has apertures (2) adjacent to the antenna (10) to permit an electro-magnetic signal to pass through the body member (1) after transmission from, or for reception by, the antenna (10).

  • Patent number: 5817937
    Abstract: A combination drill motor with measurement-while-drilling sensor apparatus includes a rotor within a stator. The rotor rotates and gyrates in response to fluid flow through the stator. An outer housing assembly having a bearing housing and a sensor housing is connected to the stator. A drive shaft is concentrically located within the bearing housing. A bearing assembly is positioned between the bearing housing and the drive shaft. A sensor cartridge assembly having a longitudinal throughbore is suspended within the sensor housing. A power transmission assembly connects the rotor to the drive shaft. The power transmission assembly includes a shaft assembly extending through the longitudinal throughbore in the sensor cartridge assembly. An annular space is formed in the longitudinal throughbore between the sensor cartridge assembly and the shaft assembly and the fluid flows through the annular space.

  • Patent number: 5690434
    Abstract: A downhole tool bearing assembly is provided which utilizes a secondary annular threaded locknut and a compression ring in order to take up tolerance stack-up and to provide supplemental preload through a bearing housing assembly, thus helping to ensure against accidental disassembly during operation. The bearing housing assembly is comprised of a prepackaged subassembly of thrust bearings, sleeves and, optionally, "BELLEVILLE"-type disk springs which can be quickly and easily installed onto a downhole tool drive shaft or other similar apparatus by maintenance personnel having a minimum of training. The bearing housing assembly is designed such that reconfiguration involves little more than removal and reinstallation in the opposite orientation, thereby overcoming the need to reconfigure the bearing assembly one bearing at a time.
