  • Patent number: 7152687
    Abstract: A ported expandable tubing having an outer valve sleeve which closes the ports upon tubing expansion. An elastomeric sealing member may be carried between the tubing and the valve sleeve to improve closing of the ports. The elastomeric sealing member may be shaped and positioned to operate as a check valve before tubing expansion. Various fluids may be flowed from the ported tubing into a borehole, or from the borehole into the ported tubing, before tubing expansion. After expansion, the ports are closed by residual clamping forces between the sleeve and tubing. By applying sufficient internal pressure to overcome the clamping forces, fluids can be flowed from the tubing into the borehole after expansion.

  • Patent number: 7117941
    Abstract: The present inventions relate to improved apparatus and methods for radially expanding tubulars, such as tubing, casing and sand-control screen assemblies in a subterranean oil or gas well, and more specifically, to a variable diameter expansion tool for expanding downhole tubulars to varying diameters. In general, the inventions provide apparatus and methods for radially expanding a tubular, such as pipe, tubing, screen or screen assembly, deployed in a subterranean well by moving an expansion tool axially through the well. An automatically infinitely variable-diameter expansion cone tool is provided. A variable-diameter cone is provided, movable between an expanded position and a retracted position. The cone is enlarged to its expanded position and advanced through expandable components until a restriction is reached. At the restriction, the variable-diameter cone automatically retracts enough to allow the tool to continue advancing through the wellbore.

  • Patent number: 7108062
    Abstract: An expandable well screen provides increased collapse, torsional and tensile strength. In a described embodiment, an expandable well screen includes a generally tubular base pipe and an external filtering media. The well screen is configured to have sufficient torsional and tensile strength for conveyance and positioning in a wellbore, while also having sufficient strength to prevent collapse when the screen is radially expanded.

  • Patent number: 7063163
    Abstract: A multi-layer deformable composite construction. In a described embodiment, a method of expanding a structure in a wellbore includes the steps of: positioning the structure in an unexpanded configuration in the wellbore, the structure including a wall made up of multiple layers; expanding the structure to an expanded configuration while permitting relative displacement between the layers; and then preventing relative displacement between the layers.

  • Patent number: 6854522
    Abstract: The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

  • Patent number: 6854521
    Abstract: A well completion system for creating a seal between a production tubing (30) and a well casing (34) positioned within a wellbore (32) comprises a production packer (46) that includes a section of the production tubing (30) and at least one seal element (60). The production tubing (30) is then positioned within the well casing (34) that lines the wellbore (32). An expander member (56) that is positioned within the production tubing (30) then travels longitudinally through the production packer (46) to expand the section of the production tubing (30) downhole that includes the seal element (60). This expansion creates a sealing and gripping relationship between the production tubing (30) and the well casing (34).

  • Publication number: 20040194950
    Abstract: A well tool assembly interconnection method is provided. In a described embodiment, a continuous tubing string has connectors positioned corresponding to desired locations for tool assemblies in a well. The tubing string is wrapped on a reel and transported to a well. As the tubing string is deployed from the reel into the well, the tool assemblies are interconnected between the connectors. A tool assembly having sensors embedded in a sidewall thereof is also provided.

  • Patent number: 6772841
    Abstract: An expandable float shoe and associated methods are provided. In a described embodiment, an expandable float shoe is attached to a leg of an expandable wellbore junction. The float shoe and leg are radially compressed, such as by folding along their axial lengths. The wellbore junction is conveyed into a well and expanded by applying pressure therein. The float shoe expands outward, along with the leg of the wellbore junction.
