Abstract: A technology is described for controlling an electric choke actuator included in a drilling rig. An example system can include a computing device configured to provide position data for an electric choke actuator configured to control a well choke valve in selective fluid communication with a blow-out preventer arranged to close a borehole. The system can receive a choke position command to move the electric choke actuator from a first position to a second position, whereupon a control signal can be sent to the electric choke actuator that causes the electric choke actuator to move from the first position to the second position. Position data for the electric choke actuator can be updated to indicate the second position.

Abstract: Systems and methods of pressure testing well production equipment, such as a blowout preventer stack and a choke manifold are disclosed. The system may include a pressure testing tool disposed in selective fluid communication with the blowout preventer stack and the choke manifold and may be arranged to permit independent pressure testing of valves of the blowout preventer stack and valves of the choke manifold without breaking connections between the blowout preventer stack and the choke manifold.

Abstract: A drilling system for facilitating extraction of subterranean natural resources comprises a blow-out preventer arranged to close a borehole and divert a fluid to a choke valve operable by an electric choke actuator. A choke system is integrated into a drilling rig control system, such that a motor control center of the drilling control system also controls a variable control device that operates the electric choke actuator. The motor control center receives and transmits rig data, comprising both choke position data and rig control data. A user interface device, communicatively coupled to the motor control center, displays information pertaining to the rig data and is operable to transmit choke control commands to the motor control center for operational control of the electric choke actuator. The choke control system is remotely operable from a remote location that overrides the choke control system.

Abstract: A BOP test apparatus may include an outer frame, a hydraulic pump, the hydraulic pump powered by an electric motor, and a charger pump, the charger pump powered by a second electric motor. The BOP test apparatus may also include a regulator, the regulator positioned to regulate the pressure of a fluid pumped by the hydraulic pump and a valve, the valve positioned to open or close fluid flow from the hydraulic pump to an outlet.
