Abstract
A shifting tool for use in a wellbore includes a tubular housing having a bore formed therethrough; a tubular mandrel disposed in the housing and longitudinally movable relative thereto; and an engagement member moveable relative to the housing between an extended position, a released position, and a retracted position, wherein: the engagement member is movable from the retracted position to the extended position in response to movement of the mandrel relative to the housing, and the engagement member is further movable from the extended position to the released position in response to movement of the mandrel relative to the housing.
Claims22
A shifting tool for use in a wellbore, comprising:
- a tubular housing;
- a tubular mandrel disposed in the tubular housing and longitudinally movable relative thereto;
- a rotor disposed around the tubular housing and rotatable relative to the tubular housing;
- and
- a gear train disposed in the tubular housing having at least one or more gears, wherein the gear train is configured to rotate the rotor relative to the tubular housing.
An assembly for use in a wellbore, comprising:
- a shifting tool, comprising:
- a first tubular housing;
- a first tubular mandrel disposed in the first tubular housing and longitudinally movable relative thereto;
- a rotor coupled to the first tubular mandrel and rotatable relative to the first tubular housing, wherein a driver is disposed in the rotor and movable from a retracted position to an extended position;
- a gear train disposed in the first tubular housing having at least one or more gears, wherein the gear train is configured to rotate the rotor relative to the first tubular housing;
- and
- a power sub, comprising:
- a second tubular housing;
- and
- a second tubular mandrel having a first profile configured to receive the driver when the driver is in the extended position, wherein the second tubular mandrel is rotatable relative to the second tubular housing by the driver when in the extended position.
A method of operating a shifting tool, comprising:
- deploying the shifting tool into a wellbore, the shifting tool comprising:
- a tubular housing;
- a mandrel disposed in the tubular housing and longitudinally movable relative thereto;
- a rotor coupled to the mandrel and rotatable relative to the tubular housing;
- and
- a gear train disposed in the tubular housing having at least one or more gears, wherein the gear train is configured to rotate the rotor relative to the tubular housing;
- moving the mandrel longitudinally relative to the tubular housing;
- and
- rotating the rotor relative to the mandrel in response to a longitudinal movement of the mandrel.
A shifting tool for use in a wellbore, comprising:
- a tubular housing;
- a tubular mandrel disposed in the tubular housing and longitudinally movable relative thereto, wherein the tubular mandrel has a plurality of teeth;
- a rotor coupled to the tubular mandrel and rotatable relative to the tubular housing, wherein the rotor has a plurality of teeth;
- and
- a gear train disposed in the tubular housing having at least one or more gears, wherein the gear train is configured to rotate the rotor relative to the tubular housing, wherein the one or more gears of the gear train comprises:
- a worm gear engaged with at least one tooth of the plurality of teeth of the tubular mandrel;
- a spur gear engaged with at least one tooth of the plurality of teeth of the rotor;
- and
- a shaft, wherein the worm gear and the spur gear are connected to the shaft.
