Abstract: A well construction system with motor equipment having at least one of a drawworks motor, a top drive motor, or a combination thereof, and an electrical power system having a power recovery and regeneration system. The power recovery and regeneration system includes at least one energy storage device that is not a capacitor bank. The well construction system may be operated by generating AC power that is made available on an AC node, converting AC power available on the AC node to DC power available on a DC node, storing energy based on DC power available on the DC node by the power recovery and regeneration system, and regenerating the stored energy from the power recovery and regeneration system to AC power, DC power, or a combination thereof for consumption by an electrical consumer of the well construction system.

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.

Abstract: An example well construction system includes well construction equipment, a power supply system, and a control system. The well construction equipment performs well construction operations. The power supply system outputs electrical power to the well construction equipment. The power supply system includes an electrical generator unit and a control system including a processor and a memory storing a computer program code. The computer program code causes the control system to control an electrical power output level of the power supply system during the well construction operations. The computer program code also causes the control system to control operation of the well construction equipment during the well construction operations based on the electrical power output level during the well construction operations and an electrical power demand level of the well construction equipment during the well construction operations.

Abstract: An assembly may include a frame moveable from a first location to a second location, a pipe manifold, and an equipment. The pipe manifold and the equipment may be coupled to the frame. The pipe manifold may include a plurality of valves. The pipe manifold may obtain an amount of fuel from one of the various valves. The valve may be configured to couple with a fuel storage device.

Abstract: Systems and methods for dissipating heat from an electrical component using an external structure of a trailer or shed as a heat sink are disclosed. A heat-producing electrical component such as a variable frequency drive (VFD) using an insulated-gate bipolar transistor (IGBT) is housed in a trailer and is thermally coupled to an exterior wall of the trailer to use the wall as a heat sink to dissipate heat from the VFD and IGBT. An adapter can be used to couple VFDs and IGBTs of different sizes and configurations to a support site on the exterior wall.

Abstract: Electrical power transmission for well constriction apparatus via a rotatable spool positioned at and affixed to a moveable well construction apparatus at a wellsite and an electrical power cable at least partially wound on the rotatable spool and connected to stationary equipment at an end of the electrical power cable distal from the rotatable spool.

Abstract: Apparatus and methods pertaining to a moveable well construction apparatus to be electrically energized via an electrical power transmission path extending between a stationary power source and the moveable well construction apparatus. The path comprises cables and connectors. A system comprises a detector operable for generating information indicative of whether the path is properly installed. The system permits the path to be electrically energized when the detector-generated information indicates the path is properly installed, and prevents the path from being electrically energized when the detector-generated information indicates the path is not properly installed.
