  • Patent number: 9249642
    Abstract: A self-actuated cyclical flow interruption valve on a deployment tool is positioned at a proximal end of a well completion assembly. Fluid is pumped though the self-actuated cyclical flow interruption valve and vented immediately distal of the valve, to return to surface of the well. A water hammer pulse is generated each time the self-actuated cyclical flow interruption valve closes, thereby generating an impact force that acts to push the completion equipment distally into the well. The continuous cyclic force of the impact facilitates placement of the completion equipment where desired in the well, including within a horizontal extension of the well. Fluid discharged through the self-actuated cyclical flow interruption valve circulates up to the surface through a vertical and inclined section of the well.

  • Patent number: 9004183
    Abstract: A string is equipped with a braking device to regulate its speed into the wellbore through an existing tubular. When the targeted amount of overlap with an existing tubular is accomplished the two tubulars are then joined together. The braking system can take many forms such as externally mounted mechanisms that are speed responsive to vary the braking force. The inside of the tubular can have trapped gas to provide buoyancy and reduce the dropping speed. The braking can be accomplished hydraulically through regulated flow through the tubular or by a combination of a hydraulic and mechanical device. The momentum of the dropped string can also be controlled with a swage device that at the appropriate location lands on a taper and wedges or fuses itself to the surrounding tubular to gain support from the surrounding tubular.

  • Patent number: 8997858
    Abstract: A liner hanger/packer apparatus operates by sequential expansion of a slip ring and then a sealing element. The hanger slips are set by pressure on a seated ball actuating anchor slips to grip followed by a stroker assembly and a swage making a first movement. The ball seat is defeated and the liner is cemented. A pickup force extends landing dogs so that a subsequent set down force releases a flapper to close and closes off fluid ports associated with the anchor slips so that pressure on the closed flapper sets the anchor and strokes the swage a second stroke to set the sealing element. A rupture disc breaks in the flapper after further relative movement of mandrel components to open the fluid displacement ports so that the anchor is in pressure balance to backpressure developed from fluid moving through the now broken disc as the running tool is removed.

  • Patent number: 8820419
    Abstract: A tieback receptacle is configured with an exterior cone and externals seals with a clearance space to accept a tieback shoe that will wash over the receptacle and expand when landed and advanced over the cone. The lower end of the shoe is tapered so that the thickness opposing the upper seal adds to burst and collapse resistance while the tapered lower end allows a thicker receptacle to be used in the area of the lower seal. The expansion can be accomplished with setting down weight which can also enhance the set of the liner hanger below. Minimal expansion in the order of 3% or less is needed. Exterior slots create cement flow passages and a no-go for the stem to prevent damage to the box further below. A metal to metal seal is created at the cone that is straddled by the exterior seals on the extension.

  • Publication number: 20140238748
    Abstract: Drilling assemblies, systems and methods enable a wellbore to be drilled and lined with a slotted liner. A drilling system includes a liner assembly with a drill string in a bore thereof. The drill string and the liner assembly can be selectively coupled together to restrict relative motion between the liner assembly and the drill string. The liner assembly includes a slotted liner portion through which fluid may flow. As the drilling system is used to drill a wellbore, the liner assembly is simultaneously positioned within the wellbore. Once the wellbore is drilled to a desired depth, the drill string can be disengaged from the liner assembly and retrieved from the well. Production fluids such as oil and gas may then be transferred uphole through the liner assembly.

  • Patent number: 8794312
    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: 8783368
    Abstract: A running tool for well drilling operations is carried by a running string into and out of a wellbore. A collet is carried by the running tool, the collet having fingers with a radially expanded position arranged to latch against a wellbore shoulder in the wellbore. The fingers are resiliently and radially contractible. A shear element is carried by the collet, the shear element preventing the fingers from radially contracting to unlatch the running tool while the shear element is intact. If a selected axial force is applied against the shear element, it shears, freeing the collet fingers to retract. The collet may be part of a tool to set and release a liner hanger from engagement with a string of casing.

  • Patent number: 8783343
    Abstract: Embodiments of the invention generally relate to tools and methods for hanging and/or expanding liner strings. In one embodiment, a method of hanging a liner assembly from a previously installed tubular in a wellbore includes running the liner assembly and a setting tool into the wellbore using a run-in string. The setting tool includes an isolation valve and the liner assembly includes a liner hanger and a liner string. The method further includes sending an instruction signal from the surface to the isolation valve, wherein the isolation valve closes in response to the instruction signal and isolates a setting pressure in the setting tool from the liner string; and increasing fluid pressure in the setting tool, thereby setting the liner hanger.

  • Publication number: 20140196890
    Abstract: A liner hanger/packer apparatus operates by sequential expansion of a slip ring and then a sealing element. The hanger slips are set by pressure on a seated ball actuating anchor slips to grip followed by a stroker assembly and a swage making a first movement. The ball seat is defeated and the liner is cemented. A pickup force extends landing dogs so that a subsequent set down force releases a flapper to close and closes off fluid ports associated with the anchor slips so that pressure on the closed flapper sets the anchor and strokes the swage a second stroke to set the sealing element. A rupture disc breaks in the flapper after further relative movement of mandrel components to open the fluid displacement ports so that the anchor is in pressure balance to backpressure developed from fluid moving through the now broken disc as the running tool is removed.
