  • Patent number: 8857526
    Abstract: A mechanism configured for mechanical self-deployment in a well. The mechanism may be primarily an open or closed-cell polymer foam positioned downhole in a pre-compressed state. Subsequently, the mechanism may be released from a housing for self-deployment and engagement with a wall of the well. Such a mechanism may serve the conventional purpose of a downhole packer or other similar restriction devices. Additionally, due to the self-deploying nature of the device, multiple such devices may be linked in series based upon user-determined criteria at the time of application. Thus, a reduction in the number of trips in the well may generally be realized.

  • Publication number: 20140251593
    Abstract: Shear member designs in various formats are presented with additional features for segment retention and subsequent removal after a shearing event and removal of the tool from a subterranean location. In some embodiments a portion of the shear member is retained by threads so that the segment stays in the part and then can be removed at the surface with putting a notch in the segment and removing it with a screwdriver. In another embodiment a retaining pin in an intersecting bore can hold onto a sheared remnant of the shear pin by pushing the remnant laterally in the bore that it is mounted. Another design for a shear ring uses a split design with the right angle portion of the ring that gets sheared appearing in segments so that the ring can be rapidly snapped into a groove at its outer periphery followed by a retaining cap facilitating removal.

  • Patent number: 8763686
    Abstract: A linkage device separate from the integrated slips bridge links the pair of spaced-apart members of each slip to prevent sizeable fractured bits from moving away in the event of a fracture in the slip. The linkage device comprises a pair of ductile steel bars the ends of which loosely anchor in holes in each slip member, the holes being located at both sides of the slips at opposite ends of a groove that houses the linkage bar preventing it from falling out of the holes. In this way, a fractured slip may continue to assist in setting the tool and, moreover, potential hazardous interference in further tool operations are avoided. Furthermore, tool damage including slips fracture is reduced by a resilient damper material which buffers the lower cone as it slides down on the slip-holder cage during a tool release operation.

  • Patent number: 8662161
    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.

The closure body, at least a part thereof, is moved beyond the lower end of the borehole to enter into the raw material filled cavity, and is expanded within the cavity below the borehole and, with an axially sealing surface, is urged from below against the cavity's sealing surrounding the borehole. With regard to the device, to achieve this, the expandable part has an expandable portion with an axially sealing surface which, once expanded, has a diameter significantly greater than the diameter of the borehole. In order to permit the sealing part being pushed against the borehole wall once it has been expanded inside the cavity, a reversible feed motion or advancing drive is provided.

  • Publication number: 20130248192
    Abstract: One or more fluid-jetting subs having jet ports and a packer element are incorporated into a completion string for deployment into a wellbore for perforation and treatment operations. The packer element, being either an inflatable packer element or a compressible packer element, is downhole of the jet ports and is fluid pressure actuated. Pressure in the completion string is maintained at a pressure higher than in the annulus thereabout to keep the packer set for sealing the annulus therebelow while fluid is delivered through the jet ports for perforating or treatment such as fracturing.

  • Publication number: 20130213645
    Abstract: A downhole formation testing and sampling apparatus. The apparatus includes an expandable packer having a radially contracted running configuration and a radially expanded deployed configuration. At least one elongated sealing pad is operably associated with the expandable packer such that operating the expandable packer from the running configuration to the deployed configuration establishes a hydraulic connection between the at least one elongated sealing pad and the formation. The at least one elongated sealing pad has at least one opening establishing fluid communication between the formation and the interior of the apparatus. In addition, the at least one elongated sealing pad has an outer surface operable to seal a region along a surface of the formation to establish the hydraulic connection therewith. The at least one elongated sealing pad further has at least one recess operable to establish fluid flow from the formation to the at least one opening.

  • Publication number: 20130213672
    Abstract: A downhole apparatus having a radially expanding portion and a support structure are described. The support structure comprises an attachment means for coupling to the apparatus and a support portion configured to be deployed from a first unexpanded condition to a second expanded condition by expansion of the apparatus. In one aspect of the invention, the downhole apparatus is expanded by exposing the swellable material to at least one predetermined fluid, and the support structure abuts the swellable material in its expanded form. A method of use and its application to a well packer, a hanging member, an anchor and a centralising apparatus are described.

  • Patent number: 8490708
    Abstract: A downhole apparatus, such as a wellbore packer, is provided with a swellable member and a fluid supply assembly. The fluid supply assembly is to receive fluid and expose the swellable member to the fluid to cause expansion of the swellable member, and comprises a support structure for supporting the swellable member on the body. In a preferred embodiment, the support structure defines a chamber and is configured to allow fluid to flow and access the swellable member. A method of use and method of sealing a wellbore is described.

  • Publication number: 20130180736
    Abstract: The present invention relates to an expansion device to be inserted in a casing or well tubular structure for expanding an annular barrier downhole. The annular barrier comprises a tubular structure for mounting as part of the well tubular structure, an expandable sleeve surrounding the tubular structure, and a connection part connecting the expandable sleeve with the tubular structure. The tubular structure has an opening and two projecting elements decreasing an inner diameter of the tubular structure. The expansion device comprises a tubular part extending between a first and a second end part, the tubular part comprising at least one opening arranged between the first and the second end; an inner face surrounding an inner space; and an outer face. Furthermore, the expansion device comprises at least a first and second sealing element sealingly connected to the outer face of the tubular part.

  • Publication number: 20130161000
    Abstract: The invention provides a method and apparatus for use in a wellbore gravel pack operation. The method comprises providing an apparatus in a downhole annulus. The apparatus comprises a mandrel and a swellable element formed from a material selected to increase in volume when exposed to a downhole stimulus. The method comprises placing a gravel pack below the apparatus via the downhole annulus in which the apparatus is located, and placing a gravel pack above the apparatus. Subsequent to placing the gravel packs, the swellable element is increased in volume to create an annular barrier in the wellbore. The invention allows isolation of multiple intervals of a well in a single gravel pack operation using swellable elastomers, and does not rely on the use of shunt tube alternate path systems.
