Abstract: An apparatus for temporarily connecting a first tool part to a second tool part of a tool includes a plurality of frangible members connecting the first tool part to the second tool part. The frangible members break only after being subjected to a predetermined applied force. The frangible members cooperate to differentially resist loading applied to the tool.

Abstract: A liner is cemented bottom up and then top down followed by setting the simultaneously set liner hanger/packer and releasing the running tool. In one embodiment the ported sub for top down cementing has ports opened and then closed with multiple dropped or pumped balls one of which lands in the running tool to set the hanger packer with pressure before running tool removal. A dart with a leading ball can follow the top down cement to close the ported sub and thereafter land in the liner hanger/packer to set it with pressure. A dart can lead the top down cement and open the ported sub followed by a second dart behind the top down cement to close the ported sub and land in the liner hanger/packer to set it and to release the running tool. The ported sub can be operated in other ways such as motors responsive to a remote signal.

Abstract: Wall openings in a mandrel of a liner hanger/packer are eliminated and setting is accomplished with pressure against a landed object in a running tool. The wall of the running tool leads to a sealed annular space with a movable seal attached to a setting sleeve and the other end is a packer cup supported by the running tool. The setting sleeve sequentially sets the slips and releases the running tool followed by setting the packer seal. Optionally a dog sub can be used to set with set down weight on the setting sleeve. The set positions are locked in. The slips can be alternatively set with release of a contained spring force. The setting sleeve seal can be sheared out to allow removal of the running tool.

Abstract: In one aspect, a method of completing a wellbore is disclosed that in one non-limiting embodiment includes: placing a completion assembly in the wellbore, the completion assembly including a first link along an outside the completion; placing a second link between a surface location and a subsea location; placing a string having a third link between the first link and the second link; and connecting the third link to the first link and the second link to provide a continuous link between the completion assembly and the surface location.

Abstract: A tieback string assembly features a metal to metal nose seal weighted down with casing extending between a lower end of a telescoping joint optionally having metal to metal seals for spacing out to a wellhead casing hanger. The telescoping joint is located so that the hanging weight off the telescoping joint lower end is sufficient to energize the metal to metal nose seal engaged to a sleeve or a liner top packer. The tieback string is smaller in outside diameter than the parent casing through which it is run. The assembly retains high pressure by avoiding lower pressure rated elastomers in the nose seal or the telescoping joint.

Abstract: In a completion for producing methane the bottom hole assembly has a base pipe with porous media surrounding it for equalizing flow along the base pipe. A shape memory polymer foam surrounds the porous media. The borehole can be reamed to reduce produced methane velocities. Surrounding the shape memory polymer is an exterior layer of consolidated proppant or sand that can self-adhere and/or stick to the polymer foam. The proppant or sand can be circulated or squeezed into position although, circulation is preferred. The borehole may enlarge due to shifting sands in an unconsolidated formation as the methane is produced. The bottom hole assembly helps in fluid flow equalization and protects the foam and layers below from high fluid velocities during production.

Abstract: A retaining device for a threaded connection that is expanded holds the connection together to prevent leakage. In a two step thread the retention device is located between the steps and comprises a nose in a groove that holds aligned surfaces together for a metal to metal connection and allows for relative axial movement at the same time.

Abstract: An open hole packer uses mandrel expansion and a surrounding sealing element that can optionally have a swelling feature and further a seal enhancing feature of a ring with an internal taper to match an undercut on the mandrel exterior. As a swage progresses to the taper at the transition between the ring and the extending flat fingers, the fingers get plastically deformed in an outward radial direction to push out the sealing element. Shrinkage of the mandrel axially due to radial expansion brings a ring on the mandrel outer surface under the fingers to act as a support for the fingers against the seal which is pushed against the open hole. Mirror image orientations are envisioned to aid in retaining pressure differentials in opposed directions. Another external mandrel ring extends into the seal to keep its position during differential pressure loading.

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.
