Abstract
A system includes a ball valve positionable along a fluid flow path of a wellbore. The ball valve is movable between an open position, where fluid is able to flow through the fluid flow path, and a closed position, where the fluid is prevented from flowing through the fluid flow path. The system also includes an electric motor coupled to a drive system within a trunnion of the ball valve. The electric motor drives rotation of the ball valve to move the ball valve between the open position and the closed position. Further, the system includes a power source electrically coupled to the electric motor to provide power to the electric motor.
Claims20
A system comprising:
- a ball valve positionable along a fluid flow path of a wellbore, the ball valve being movable between an open position, where fluid is able to flow through the fluid flow path, and a closed position, where the fluid is prevented from flowing through the fluid flow path;
- an electric motor coupleable to a drive system within a trunnion of the ball valve and positionable to drive rotation of the ball valve to move the ball valve between the open position and the closed position;
- and
- a power source electrically coupleable to the electric motor to provide power to the electric motor.
An electric ball valve assembly comprising:
- a ball valve coupleable to a wellbore comprising a through-bore, the ball valve being rotatable between (i) an open position where a fluid is able to flow through the through-bore and (ii) a closed position where the fluid is prevented from flowing through the through-bore;
- an electric motor positionable adjacent to a first trunnion of the ball valve to rotate the ball valve between the open position and the closed position;
- and
- a power source positionable proximate to the electric motor to provide power to the electric motor.
A method comprising:
- receiving a valve control signal from a wireless telemetry system;
- receiving electric power from a primary cell or a rechargeable battery pack;
- providing an actuation force to a ball valve coupleable to a wellbore using an electric motor powered by the electric power;
- and
- moving the ball valve between an open position and a closed position using the actuation force, wherein in the open position, a fluid is able to flow through a through-bore of the ball valve, and in the closed position, the fluid is prevented from flowing through the through-bore.
