    Abstract: A sensor assembly may include a housing made of a non-magnetic material. The housing may define an interior chamber. A shaft may extend from the housing. A bearing may be positioned around the shaft. An impeller may be positioned around the shaft and the bearing, and the impeller may include a magnetized portion. A sensor may be positioned within the interior chamber and/or proximate the magnetized portion. The sensor may detect the magnetized portion of the impeller to sense a rate of rotation of the impeller. The rate of rotation of the impeller may correspond to changes in flow rate of the fluid. As the flow rate of the fluid, and the rate of rotation of the impeller change in predetermined manners, control signals may be conveyed to activate a tool.

    Abstract: Systems and methods disclosed herein are directed to drilling rigs and, more specifically, to controlling the rotation of a drill string assembly to limit effects of irregular rotary movements form an AC induction motor driven by an inverter, associated with operation of a drilling rig. The systems and methods obtain rotational conditions of the rotary drilling system driven by a motor. Additionally, the systems and methods continuously generate, in response to a change in the rotational conditions, a supplied power to the motor at a frequency selected on relation of torque versus speed for the motor based on a virtual drive characteristic. The systems and methods can determine of the virtual drive characteristic to optimize coupling between the motor system and the rotational drilling system, as well as minimizing the effect of resonance and total noise.

    Abstract: A method for transmitting data from a downhole instrument to a surface location includes running the downhole instrument into a wellbore on a line. The downhole instrument and at least a portion of the line are positioned inside a drill string. The downhole instrument includes first and second sets of fingers that contact an inner surface of the drill string. The downhole instrument measures an effect occurring in the drill string. The effect is due to perturbations in the drill string during a drilling process.

    Abstract: A technique facilitates tool operation with mobile pistons submitted to differential pressure. The technique utilizes a mobile piston slidably mounted in a corresponding piston passage. The piston passage is defined by a passage wall surface, and the piston may be moved linearly along the piston passage under the influence of an actuating fluid or to pump a fluid. The exterior surface of the piston and/or the passage wall surface have a groove or a plurality of grooves located and arranged to collect particulates from the fluid. Removal of the particulates facilitates actuator piston function by reducing, for example, third body abrasion and jamming of the piston.

    Abstract: Methods and apparatus for simultaneous operation of a variable-frequency drive (VFD) and a controller. The VFD drives an electric motor of a drilling rig machine. The controller controls temperature of an insulated-gate bipolar transistor device (IGBT) of the VFD by controlling an air mover in response to real-time temperature data. The air mover generates airflow into a passage, the airflow thereby interacting with radiating members extending into the passage from a heat sink thermally coupled with the IGBT in the inner housing outside the passage.
