  • Patent number: 10954732
    Abstract: A BHA features an MWD tool connected to a running tool supporting a whipstock that is connected to an open hole anchor. The anchor is flow set and after the anchor is set the running tool collets release from the whipstock to allow cement to be pumped through the anchor to hold the set position. The collets are released from the whipstock also with flow and after the anchor has been set. One way is to use nozzles in series. Another is to run in with a ball on the anchor seat, set the anchor and blow out the ball seat so flow can again be used to release the running tool collets. Another is suspending a ball above the anchor seat, releasing the ball with pressure cycle, open another flow passage to allow collet release of the whipstock. Finally, pressure can be used to release the running tool collets.

    Abstract: A new cement valve is disclosed for use in the production of an oil or gas well where hydraulic fracturing has been employed. In particular, the embodiments include a cement valve having a reclosable valve. When properly located, a first piston sleeve is hydraulically actuated to open the cement ports on the tool. After the cement has been pumped through the tool and the cement ports to a wellbore annulus, a blocking ball is dropped to stop flow through the tool. The tool is internally pressurized. The pressure overcomes shear pins to force downward movement of a ball housing inside the cement valve. This movement translates a travelling pin along a guide path, which rotates a ball valve inside the ball housing, releasing the blocking ball to open up the internal flow path through the cement valve at the same time the cement ports are closed.

  • Patent number: 10428623
    Abstract: A ball dropping system includes a ball retention feature. The ball retention feature includes an ejection arrangement blocked from activating in a first condition of the ball dropping system, activatable in a second condition of the ball dropping system, and activated to eject a ball from the ball dropping system that is releasably secured by the ball retention feature in a third condition of the ball dropping system. A setting sleeve is movable from a first position to a second position with respect to the ejection arrangement. The setting sleeve has the first position to block the ejection arrangement from activating in the first condition of the ball dropping system. The setting sleeve is movable to the second position to render the ejection arrangement activatable in the second condition of the ball dropping system.

  • Patent number: 10400529
    Abstract: Apparatus and method for anchoring a morphable tubular in a wellbore in which an anchoring system is arranged around the circumference of an expandable portion of the tubular member. The anchoring system has a gripper element with oppositely arranged inclined surfaces and wedge elements having inclined surfaces mutually arranged on either side of the gripper element with at least one of the wedge elements being a beam spring. Following morphing of the tubular member the anchoring system is configured to maintain the gripper element in a radially extended position by action of the at least one beam spring and thereby increase the load bearing capacity of the morphed tubular member in the wellbore.

  • Patent number: 10301902
    Abstract: Apparatuses and methods for an anti-preset and anti-reset mechanism for a retrievable packer are disclosed herein. These features may be used to prevent the packer from being actuated prematurely during deployment downhole and to prevent the packer from re-actuating during retrieval. An apparatus may include a mandrel, a slip assembly disposed about the mandrel, a collet member disposed about the mandrel and adjacent to the slip assembly, and a cover sleeve disposed about the mandrel and coupled to the collet member. A method for releasing a packer may include cutting a mandrel, sliding a cover sleeve and a collet member having a collet lug downhole with respect to the mandrel, applying force from the collet member to the slip assembly, disengaging the slip assembly from a well casing, and engaging an inner surface of the collet lug to a protrusion on the mandrel.
