  • Patent number: 9828833
    Abstract: A valve assembly, and related system and method, with a sleeve having an inner surface with a diameter, an outer surface, and a plurality of openings extending between the inner surface and the outer surface. A split ring having one or more segments and an expandable or collapsible body with a seating surface and an outer diameter extending from the body is at least partially within the inner surface of the sleeve. The split ring and sleeve may be placed in a variable diameter housing such that contact of the outer diameter with a smaller diameter section of the housing causes the split ring to close, whereas contact with an larger diameter of the housing allows the split ring to open. In certain embodiments, a spring element, which may be the split ring itself, applies force to move the split ring from an open to closed position. A spring may be positioned around a portion of the sleeve and in an annular space at least partially defined by an annular body and the second cylindrical outer surface.

  • Patent number: 8646523
    Abstract: Porous objects, such as porous balls, may be employed within telescoping devices to control proppant flowback through a completed well during production. The telescoping devices may connect a reservoir face to a production liner without perforating. Acid-soluble plugs initially disposed within the telescoping devices may provide enough resistance to enable the telescoping devices to extend out from the production liner under hydraulic pressure. The plugs may then be dissolved in an acidic solution, which may also be used as the hydraulic extension fluid. After the plugs are substantially removed from the telescoping devices, the reservoir may be hydraulically fractured using standard fracturing processes. The porous balls may then be inserted into the telescoping devices to block proppant used in the fracturing process from flowing out of the reservoir with the production fluids.

In some embodiments, the surface casing head includes an outer tubular member insertable through a diverter of an installed conductor system, an inner tubular member at least partially disposed within and moveable relative to the outer tubular member, and a sleeve ring rotatably coupled to the inner tubular. The outer tubular member has an annular recess. The sleeve ring includes a snap ring that is displaceable between an extended position and a retracted position. In the extended position, at least a portion of the snap ring is received within the annular recess, and the outer tubular member is axially immovable relative to the inner tubular member. In the retracted position, no portion of the snap ring is received within the annular recess, and the outer tubular member is axially moveable relative to the inner tubular member.

  • Patent number: 8082998
    Abstract: An apparatus (100) for controlling the connection speed of downhole connectors (316, 146) in a subterranean well. The apparatus (100) includes a first assembly that is positionable in the well. The first assembly includes a first downhole connector (316) and a first communication medium. A second assembly includes a second downhole connector (146) and a second communication medium. The second assembly has an outer portion and an inner portion. The outer portion is selectively axially shiftable relative to an inner portion, such that upon engagement of the first assembly with the second assembly, the outer portion of the second assembly is axially shifted relative to the inner portion of the second assembly allowing the first and second downhole connectors (316, 146) to be operatively connected to each other, thereby enabling communication between the first communication medium and the second communication medium.

  • Patent number: 8056619
    Abstract: An apparatus that is usable with a well includes a first equipment section that includes a first inductive coupler and a second equipment section that includes a second inductive coupler. The second equipment section is adapted to be run downhole into the well after the first equipment section is run downhole into the well to engage the first equipment section. A mechanism of the apparatus indicates when the first inductive coupler is substantially aligned with the second inductive coupler.

  • Patent number: 7950449
    Abstract: A stress and torque reducing tool has a plunger that reciprocates inside of a body. The tool is connected between the pump and the sucker rod string and reduces stress transmitted therebetween. The body and plunger have longitudinally extending surfaces located at the plunger upper end portion, which surfaces cooperate and limit rotation of the body with respect to the plunger. An upper fluid port is located in an upper end of the body, while one or more lower fluid ports are located in a lower end of the body.

  • Patent number: 7896067
    Abstract: A tool and its operating procedure are provided to protect any device while lowering into a well, and especially hydraulic devices such as sensors with expandable arms or inflatable elements such as packers. The protection is mainly important in the open hole of highly deviated or horizontal wells, for any device equipped with external seal element, delicate sensor or articulated parts. This tool features an automatic sequence controlled by a single dart or a single ball launched into the running string from the surface: when the dart or the ball lands on its seat, the pressure build-up is initially applied to a piston to extract the device from the protector without exposing it to any differential pressure, then it is automatically applied to the device itself for actuation as soon as the device is entirely pulled out of the protector.

  • Patent number: 7896090
    Abstract: A tool for subterranean use employs relative movement between a housing and a piston by pressurizing and removing pressure in a variable volume defined between them. The variable volume is sealed with packer cups preferably with one supported from the piston and the other off the housing and in opposed orientations so that the broad surface area on each packer cup abuts the surface where relative movement takes place. The downhole tasks accomplished with the relative movement can be varied and include tubular expansion, setting packers or shifting sleeves, for example. A single or multiple packer cups are tied to a structure that needs to be driven and building pressure behind a packer cup or reducing pressure ahead of it advance the piston.

  • Patent number: 7806179
    Abstract: Two subs are held in a fixed position relative to each other when assembled to a string and run into a wellbore. A reservoir of fluid is defined in a wall between the subs. The reservoir has one or more outlets connected by a short jumper line to an adjacent tool to be operated. At the appropriate time, set down weight breaks a shear pin to reduce the reservoir volume and create pressure in the exit lines. The exit lines can be connected to operating pistons in adjacent tools to actuate them or to perform other desired functions using a stream of pressurized fluid. The device can be set for one time or multiple cycles where fluid in the reservoir can be replenished and re-pressurized for multiple cycles of operation.
