  • Testable sliding sleeve valve
    Patent number: 11268347
    Abstract: A sliding sleeve valve for use in a borehole includes an outer housing including a radial housing slot, a sliding sleeve slidably disposed in the outer housing, the sliding sleeve including a radial sleeve slot and configured to have a first position that restricts fluid communication between the sleeve slot and the housing slot and a second position, spaced from the first position, that permits fluid communication between the sleeve slot and the housing slot, an actuator housing coupled to the outer housing, wherein the actuator housing includes an actuator chamber defined by an inner surface, and wherein the actuator chamber is disposed between an inner surface and an outer surface of the actuator housing, and an actuator assembly disposed in the actuator chamber, wherein the actuator assembly is configured to control movement of the sliding sleeve between the first and second positions.

  • Actuator switch for a downhole tool, tool and method
    Patent number: 9284801
    Abstract: An actuator switch for actuation of a downhole tool, the actuator switch comprising: a rheomagnetic fluid having a state convertible between a liquid and a solid by the application of a magnetic field thereto, a change in the state of the rheomagnetic fluid acting to actuate the downhole tool; and a magnet installed in the tool and moveable relative to the rheomagnetic fluid to apply or remove the magnetic field to the rheomagnetic fluid, the magnet being moved by through tubing operations in an inner diameter of the downhole tool.
