  • Patent number: 10233740
    Abstract: A control system that mitigates stick-slip vibrations at higher harmonics than currently available is disclosed. A controller of a top drive is set to a torque control mode instead of a speed control mode. The controller receives torque measurements and compares to a target torque value. The controller accelerates or decelerates the top drive by a generated current adjustment command. A slow integration speed control loop, at least an order of magnitude slower in response than the torque control loop, receives a RPM set point. The slow integration speed control loop compares the RPM set point to an actual RPM measurement and generates a torque command. The torque command is sent to the torque control loop which results in an acceleration or deceleration of the top drive to maintain a desired torque amount. The speed of the top drive is bounded by a speed limit control loop.

    Abstract: Mud pulse telemetry systems and methods may employ a downhole pulser to encode a digital telemetry data stream as pressure fluctuations in a fluid flow stream. An arrangement of spatially separated sensors acquire pressure-responsive measurements at multiple positions within the plumbing of a drill rig. A receiver collects and digitizes the measurements from the spatially separated sensors and subjects them to a principal components analysis (PCA) to determine those one or more basis vectors associated the telemetry signal. The PCA process may employ decomposition of a spatial correlation/covariance matrix or a temporal-spatial correlation/covariance tensor. The selected basis vector(s) are then used to obtain the telemetry signal for demodulation into the telemetry data stream.

  • Patent number: 9411068
    Abstract: Logging tools and methods for obtaining a three-dimensional (3D) image of the region around a borehole. In at least some embodiments, a 3D imaging tool rotates, transmitting pulses that are approximately a nanosecond long and measuring the time it takes to receive reflections of these pulses. Multiple receivers are employed to provide accurate triangulation of the reflectors. In some cases, multiple transmitters are employed to obtain compensated measurements, i.e., measurements that compensate for variations in the receiver electronics. Because reflections occur at boundaries between materials having different dielectric constants, the 3D imaging tool can map out such boundaries in the neighborhood of the borehole. Such boundaries can include: the borehole wall itself, boundaries between different formation materials, faults or other discontinuities in a formation, and boundaries between fluids in a formation.

  • Patent number: 9243488
    Abstract: A drill collar assembly allows a sensor to be mounted with the same standoff from a borehole wall independent of the size of stabilizer and borehole involved. A sensor component disposes in a receptacle in the drill collar, but does not affix in the receptacle. Instead, a stabilizer fits on the drill collar and covers the receptacle, and the sensor component mounts directly to the underside of the stabilizer so the component “floats” or “suspends” in the receptacle. The sensor component can mount at a stabilizer blade so the sensor can be positioned in closer proximity to the borehole wall to measure parameters of interest. Because the drill collar and sensor component can be used in different sized boreholes, different sized stabilizers may be positioned on the drill collar to account for the different sized boreholes while the sensor still has the same standoff.

  • Patent number: 9121223
    Abstract: A technique facilitates drilling of wellbores with a steerable system having a plurality of pads which may be selectively actuated in a lateral direction to apply a side force. Application of the side force is used to steer a drill bit. A valve system is positioned to control delivery of actuating fluid under pressure to individual pads in a manner that enables steering of the drill bit. The valve system allows drilling along a desired curve by controlling the flow of actuating fluid under pressure to specific steering pads at specific angular positions. The valve system also allows drilling along a desired trajectory by preventing exposure of the pads to the pressurized actuating fluid.
