Abstract
A variety of methods, systems, and apparatus are disclosed, including, in one embodiment, a valve system comprising: a valve; and a valve actuation assembly comprising: a linear motion actuator configured to move linearly; a cable coupled to the linear motion actuator; and a shaft coupled to the cable, wherein the cable extends from the linear motion actuator to the shaft, wherein the shaft is configured to rotate and actuate the valve in response to linear movement of the linear motion actuator.
Claims20
A valve system for use in a wellbore comprising:
- a valve configured to control fluid flow through a shunt tube downhole in a wellbore;
- and
- a valve actuation assembly comprising:
- a linear motion actuator configured to move linearly;
- a cable coupled to the linear motion actuator;
- and
- a shaft coupled to the cable, wherein the cable extends from the linear motion actuator to the shaft, wherein the shaft is configured to rotate and actuate the valve in response to linear movement of the linear motion actuator.
A well system comprising:
- a well tool;
- a flow path extending through the well tool;
- a valve disposed in the flow path;
- and
- a valve actuation assembly comprising:
- a linear motion actuator configured to move linearly;
- a cable coupled to the linear motion actuator;
- and
- a shaft coupled to the cable, wherein the cable extends from the linear motion actuator to the shaft, wherein the shaft is configured to rotate and actuate the valve in response to linear movement of the linear motion actuator;
- wherein the well tool is a packer disposed in an annulus, and wherein the flow path comprises a shunt tube.
A method for valve actuation in subterranean operations, comprising:
- moving a cable in a wellbore;
- transferring linear motion of the cable to a shaft coupled to the cable to thereby cause the shaft to rotate;
- and
- transferring rotational motion of the shaft to a valve coupled to the shaft to thereby actuate the valve, wherein the valve is disposed in the wellbore.
