  • Patent number: 9670751
    Abstract: A sliding sleeve opens with a deployed ball and applied pressure and is subjected to reverse flow pressure. The sleeve has a housing and an insert. The housing defines a first bore and defines a flow port communicating the first bore outside the housing. The insert is disposed in the first bore of the housing and has a seat held in a first direction therein. The seat engages the deployed plug in the first direction, and the insert moves, by the applied pressure against the plug engaged in the seat, axially in the first direction inside the first bore from a closed position toward an opened position relative to the flow port. The seat is disengageable from the insert in a second direction opposite to the first direction by the reverse flow and is passable at least out of the insert.

  • Patent number: 9394773
    Abstract: A device comprising multiple sliding sleeves actuated using same-sized balls has a resettable seat in an upper sliding sleeve and a non-resettable seat in a lower sliding sleeve. A dropped ball seats on the resettable seat forming a seal. Pressure applied from the surface shifts the resettable seat and an insert. Upon being shifted, the resettable seat releases the ball, which then moves downward to the lower sliding sleeve where the ball lands on the non-resettable seat and shifts the insert. After the first ball is released from the upper sliding sleeve, a biasing device shifts the insert whereby the seat is reset to catch the next ball. A second same-sized ball may then be dropped and land on the now reset first seat to further shift the first insert.

  • Patent number: 8978773
    Abstract: A downhole bypass valve utilizes a stationary sleeve defining an interior ball-seat. When a dropped ball is seated, fluid differential pressure is diverted to an annular area adjacent a first sliding sleeve. The sleeve slides in response to the pressure differential upon shearing of a shear pin, or similar, and opens ports to the wellbore annulus. Treatment or maintenance operations can then occur through the ports, which can be fitted with nozzles. A second sliding sleeve, independent from the first, is operated in response to dropping a second ball into the device. The second ball diverts fluid differential pressure to an annular area adjacent the second sleeve and movement occurs when a shear pin shears. The second sleeve covers the ports to the wellbore annulus and closes the valve. After a sliding sleeve shifts, pressure across the sleeve is equalized, allowing reverse flow without risk of accidental sleeve actuation.

  • Patent number: 8893810
    Abstract: For wellbore fluid treatment, sliding sleeves deploy on tubing in a wellbore annulus. Operators deploy a plug down the tubing to a first sleeve. The plug seats in this first sleeve, and pumped fluid pressure opens the first sleeve and communicates from the tubing to the wellbore annulus. In the annulus, the fluid pressure creates a pressure differential between the wellbore annulus pressure and a pressure chamber on second sleeves on the tubing. The resulting pressure differential opens the second sleeves so that fluid pressure from the tubing can communicate through the second open sleeves. Using this arrangement, one sleeve can be opened in a cluster of sleeves without opening all of them at the same time. The deployed plug is only required to open the fluid pressure to the annulus by opening the first sleeve. The pressure chambers actuate the second sleeves to open up the tubing to the annulus.

  • Patent number: 8863853
    Abstract: Downhole tools that have a housing, a linearly indexing driver, a reciprocating shifter, and an actuation seat. The driver is adapted for linear indexing relative to the housing from an initial position sequentially through one or more intermediate positions to a terminal position. The shifter is adapted for axial reciprocation relative to the housing and is operatively connected to the driver and adapted to index the indexed driver from its initial position sequentially through its intermediate positions to its terminal position as the shifter reciprocates. The actuation seat is mounted on the shifter and is adapted to receive a ball for actuation of the shifter and to release the ball after the shifter has indexed the indexed driver. Thus, a series of such tools may be operated by deploying a series of balls, all of the same size, through the tools.

  • Patent number: 8844634
    Abstract: A downhole circulation sub or valve includes a tubular housing with an outer port and a valve piston slidably disposed in the housing. A primary fluid flow path extends through an inner flow bore of the housing and valve piston. In a first position, the valve piston isolates the outer port to prevent fluid communication between the inner flow bore and a well bore annulus. In a second position, the valve piston is moved to obstruct the inner flow bore and expose the outer port to the inner flow bore and allow fluid communication between the inner flow bore and the well bore annulus. An indexing mechanism is coupled between the housing and the valve piston to guide the valve piston between the first and second positions. The indexing mechanism may include a rotatable component.

  • Publication number: 20140262302
    Abstract: A ball launching system includes a ball launcher with a removable ball pod and sleeve assembly that retains balls prior to injection. An interchangeable ball pod with a chamber corresponding to the ball diameter, fits into a pod sleeve and comprise the ball pod and sleeve assembly. The ball launcher further includes a housing with a moveably disposed piston that engages with the ball thereby launching it. The housing also includes a thru hole through which the piston may travel to externally indicate its position within the housing. The ball launching system also includes a control system having control inputs, which may be located remote to the ball launcher. By applying a pre-determined sequence of control inputs, the piston may engage with the balls retained in the ball pod and sleeve assembly to force the balls to be launched from the ball launcher.

  • Publication number: 20140251628
    Abstract: A sliding sleeve has an inner sleeve that moves in a housing. For example, the inner sleeve can move open relative to a port in the housing when a deployed ball engages a seat in the inner sleeve. Because the seat and the ball (if remaining) are preferably milled out of the inner sleeve after use, the inner sleeve preferably does not rotate in the housing during milling operations. To accomplish this, an anti-rotation clutch assembly in the sliding sleeve helps prevent the inner sleeve from rotating. A wedged cone is formed on a distal end of the inner sleeve and press fits into a cupped shoulder on the inside of the sleeve's housing.

  • Publication number: 20140251629
    Abstract: A downhole tool has a housing, a mandrel, a seat, and a piston. The housing defines a first bore, and the mandrel is movably disposed in the first bore and defines a second bore. The mandrel has first and second mandrel sections or upper and lower cones, and the first mandrel section defines a cross-port communicating the second bore with an annular space between the mandrel and the housing. The seat is disposed in the first bore of the housing between the first and second mandrel sections. The seat is movable to a constricted state in the first bore to catch a dropped ball and is movable to an expanded state in the first bore to pass a dropped ball. The piston is disposed in the annular space and at least temporality supports the seat in its constricted state.

  • Patent number: 8807227
    Abstract: An apparatus for pressure-testing a tubular body may be installed in the tubular-body interior. The apparatus comprises an activation-device seat, one or more bypass ports, a J-slot with an indexing pin and a spring. When an activation device, for example a ball, lands in the activation-device seat, fluid communication through the tubular body is blocked, allowing pressurization. During pressurization, the activation-device seat moves downward, causing the spring to compress and the indexing pin in the J-slot to move to the bottom position. Upon depressurization after the test, the activation-device seat moves upward, causing to spring to decompress and the indexing pin the J-slot to move to the top position. Upward movement of the activation-device seat unblocks the bypass ports, thereby reestablishing fluid communication through the tubular body. The tubular body may be drillpipe, casing or coiled tubing that is installed in the borehole of a subterranean well.
