Abstract: Apparatus, method, and a containment system for a mud tank. The system includes a pan extending from a base of the mud tank and configured to receive fluids leaked therefrom, a fluid sensor coupled with the pan, and a pump in fluid communication with the pan, wherein the pump is configured to remove fluid from the pan when the fluid sensor reads a predetermined threshold fluid level in the pan.

Abstract: An apparatus having a skid, a boom having a first end attached to the skid and pivotable around an axis proximate the first end such that a second end of the boom raises and lowers relative to the skid, and a room mounted on the skid. The apparatus may further include a raisable apparatus supported by the second end of the boom and having one or more plug panels configured to connect to one or more first cables. The apparatus may also include second cables routed from the raisable apparatus and attached to and supported at least in part by the boom, wherein the second cables may be configured to provide electrical power to the raisable apparatus.

Abstract: A mud cleaning system may include a system inlet carrying mud from a wellbore, a heater, a fluid separating system, and a system outlet carrying the mud to a holding vessel. The system inlet, the heater, the separator, and the system outlet may be fluidly connected such that mud flows from the system inlet, into the heater and the separator, and then out the system outlet.

Abstract: A method for reducing noise at a wellsite includes transmitting a plurality of first signals from a variable frequency drive (VFD) to an alternating current (AC) induction motor. A timing of a plurality of second signals is varied to control transistors in an inverter of the VFD, thereby reducing harmonic distortion of the first signals output from the VFD. The timing is varied based at least partially upon an estimation of the harmonic distortion.

Abstract: A system and method to reduce a whirl effect on a rotation of a drill string with an AC induction motor mechanically coupled to a rotary drilling system and configured to drive the rotary drilling system and the drill string attached thereto. Additionally, the system includes an electronic inverter to generate supplied power for the AC induction motor and a controller configured to drive the operation of the electronic inverter to impose a virtual drive characteristic relating a torque output of the motor with speed of the motor, determine a desired nominal operating point, and determine presence of whirl in the drill string from torque of the rotary drilling system and speed of the drill string.

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.
