Abstract: A downhole steering tool includes one or more steering blades selectively extendable from a housing. Each steering blade may be extended by fluid pressure within a steering cylinder. Each steering cylinder may be coupled to the interior of a mandrel positioned within the housing through an adjustable orifice. The adjustable orifice may be moved between an open and a partially open position. The adjustable orifice may be solenoid controlled or controlled by a ring valve. The adjustable orifice may generate one or more pressure pulses to transmit data to the surface.

Abstract: A method and apparatus are provided for securing a protective sleeve or wear sleeve to a rotary component which is rotatable relative to a rotary seal, such that the wear sleeve is in relatively rotating sealing engagement with the rotary seal. The wear sleeve is secured to the shaft by wedging a lock ring between the wear sleeve and the shaft. Wedging action of the lock ring can be effected by wedging formations, such as tapered surfaces, configured for causing wedging of the lock ring in response to operator-induced axial movement of the lock ring relative to the shaft and/or the wear sleeve. Wedging of the lock ring can be effected by cooperating screw threads on the lock ring and the wear sleeve, so that an operator can tighten the sleeve on the shaft by application of torque thereto.

Abstract: Downhole rotary steerable drill including a drilling shaft rotatably supported within a housing, the drilling shaft and housing each having a longitudinal axis. The drill can include a releasable locking mechanism for rotationally locking and releasing the drilling shaft relative to the housing, the releasable locking mechanism transitionable between locked and released configurations. The releasable locking mechanism includes a sliding plunger coupled to the housing by a coupling that permits longitudinal reciprocation of the sliding plunger relative to the housing and prevents rotation of the sliding plunger relative to the housing. The releasable locking mechanism can also include pressure-responsive piston that reciprocates between an unactuated configuration and actuated configuration in response to applied pressure from a pressuring pump.

Abstract: A directional tendency prediction system or method that provides: determining geometric parameters of a bottomhole assembly having at least a stabilizer, a bit, and an eccentering mechanism that provides a range of eccentricity settings; deriving a side force on the bit across the range of eccentricity settings; and based at least in part on the side force on the bit, determining a walk angle or dogleg severity (DLS) across the range of eccentricity settings. The resulting DLS range may be compared with requirements for a desired borehole trajectory and if suitable, the parameters may be used to configure the bottomhole assembly, and the DLS dependence may be expressed in a tabular or functional form to control steering.

Abstract: A rotary subterranean drill capable of detecting an excessive downhole pressure condition and automatically remediating the causal condition of the detected excessive pressure condition. A pressure detector coupled to a drill string of the rotary subterranean drill can sense an excessive downhole pressure condition that exceeds a predetermined value. When an excessive downhole pressure condition is sensed at the pressure detector drag members are automatically disengaged from the borehole, thereby permitting rotation of the anchorable exterior portion within the borehole.
