  • Patent number: 9739115
    Abstract: A tubular segment that has openings that are initially closed so that pressure can be conducted through the segment has the ability to open the segments by making a degradable material unblock the openings to facilitate another completion operation or production. Some applications include a slotted liner with a screen where an intermediate layer of a controlled electrolytic material initially allows the structure to conduct pressure and then after degradation allows access through the screen and the slotted liner for production. Other variations can be simply using slotted liner where the slots are closed for running it to allow circulation and then opened for production or other completion steps. The transformation can take place over time using available well fluids or it can take place with induced well conditions at the location that are initiated from the surface or locally at the location.

  • Patent number: 9447648
    Abstract: A gripper mechanism for a downhole tool is disclosed that includes a linkage mechanism. In operation, an axial force generated by a power section of the gripper expands the linkage mechanism, which applies a radial force to the interior surface of a wellbore or passage. For certain expansion diameters, the expansion force can be primarily transmitted from a roller-ramp interface expanding the linkage. For other expansion diameters, the expansion force can be primarily provided by expansion of the linkage, in which during a first stage the expansion force is primarily provided by a first link and during a second stage the expansion force is primarily provided by a second link. Thus, the gripper can provide a desired expansion force over a large range of expansion diameters.

    Abstract: A liner hanger is locked for run in to prevent accidental setting using a trapped collet assembly. The liner is internally pressurized to push a ring from which the collet extends. The collet heads leave a mandrel groove and compress a return spring while at the same time shouldering against an outer assembly that ramps the slips out on cones for a grip of the surrounding casing. Weight is released and the slips prevent the assembly attached to them from moving to hold the return spring compressed. Picking up weight releases the load on the slips of the hanger and allows the spring to retract the slips and return the collet assembly to the run in position in an exterior mandrel groove. This can be used with a relative rotation feature incorporated into the liner hanger to allow liner rotation during cementing, if desired.

  • Patent number: 8684096
    Abstract: Anchor assemblies for installation within an existing conduit. The anchor assemblies have a nondeformable mandrel, an expandable metal sleeve, and a swage. The expandable metal sleeve is carried on the outer surface of the mandrel. The swage is supported for axial movement across the mandrel outer surface from a first position axially proximate to the sleeve to a second position under the sleeve. The movement of the swage from the first position to the second position expands the sleeve radially outward into contact with the existing conduit.

  • Publication number: 20140000906
    Abstract: A liner flotation system comprises a liner, a first valve, and a second valve configured to form a gas filled chamber within the liner. The first valve is operable to allow fluid flow into the chamber, and the second valve operable to allow fluid flow out of the chamber. A sleeve is disposed in the chamber, and the first valve is movable into engagement with the sleeve to provide an indication of a position of the first valve. A method of securing a liner in a well comprises lowering a liner having a gas filled chamber in the well, actuating a valve to open fluid flow into the chamber, removing the gas from the chamber, and moving the valve into engagement with a sleeve coupled to the liner to provide an indication of a position of the valve.

  • Patent number: 8602115
    Abstract: A tractor configured for grip locking during advancement to avoid slippage, particularly in open-hole wells. The tractor is equipped with a grip lock mechanism for independently locking an anchor grip in a radially outward direction. This locking occurs sequentially in advance of the power stroke of a reciprocating drive piston associated with the anchor. Thus, radial outward expansion and gripping are ensured at the time pulling of a load in an axial downhole direction is pursued. Such grip locking may be employed throughout tractoring or intermittently, depending upon well characteristics such as formation hardness and well diameter.

  • Patent number: 8584765
    Abstract: Apparatus for a downhole tool in a well bore includes at least one locking mechanism and at least one sleeve. The locking mechanism is configured in a first position to prevent the upper slips from engaging the well bore wall before being positioned at the desired setting location in the well bore and is moveable into a second position that allows the upper slips to be moved into engagement with the well bore wall. A sleeve is moveable axially in the direction of the lower end of the downhole tool and configured to move the locking mechanism from its first to its second positions and also to move the upper slips axially relative to the downhole tool into engagement with the well bore wall.

  • Publication number: 20130248187
    Abstract: An elongated inflatable collar is securely attached to the exterior surface of a coiled tubing string before the tubing is lowered into the well for subsequent positioning at a predetermined subterranean location in the well casing. Upon inflation, the inflatable collar seals the annulus between the coiled tubing string and the well casing. A liquid injected from the surface creates sufficient hydraulic pressure on the upper surface of the inflated collar to advance the collar and the attached coiled tubing string and overcome frictional drag forces with the surrounding wall that caused the coiled tubing string to lock-up. The inflatable collar of the present invention can also be used to free a section of coiled tubing that is jammed in the formation due to buckling, by injecting a pressurized liquid into the wellbore downstream of the inflated collar to thereby apply a force to the downhole surface of the collar.

  • Patent number: RE46137
    Abstract: A tubing pressure operated sliding sleeve is used in cementing a tubular string. The sleeve is configured to hold closed as pressure builds to a predetermined value. When pressure is further raised a rupture disc blows and provides access to an integral piston disposed outside the sleeve. The back side of the piston is exposed to a low pressure or atmospheric chamber located between upper and lower seals. The sleeve thickness near the chamber can be made relatively thick to avoid flexing or bending under differential pressure because the net force to shift the sleeve is from differential pressure on the piston rather than the piston areas created by the upper and lower seals.
