  • Patent number: 6899182
    Abstract: A method of streamlining expansion of long lengths of tubulars or screen is disclosed. In one embodiment, the expansion assembly is coupled with a length of pipe that acts as a weight and has a length longer than the anticipated section to be expanded. There is a stinger that fits into the pipe above the anchor and a seal to maintain sealing contact despite the downhole advance of the expansion assembly following each stroke of the expansion device and advance of a swage. By sequentially applying and removing pressure, the desired length is expanded downhole. Alternatively, coiled tubing is connected to the expansion assembly and weights that are above it and is paid out into the well as the expansion assembly descends after each stroke.

  • Patent number: 6877564
    Abstract: A closure mechanism for a flapper features a pinion on the ear extending from the flapper that is used to mount it for pivotal movement. A spring-loaded rack meshes with the pinion or pinions on the flapper so that when the flow tube swings the flapper open, rotation of the pinion teeth advances the teeth on the rack against the force of a spring. When the flow tube is retracted, the spring pushes the teeth on the rack in the opposite direction causing a rotational movement of the flapper toward closure in contact with a conforming seat.

  • Publication number: 20040079535
    Abstract: A method of centralizing tubulars prior to cementing and subsequent expansion involves using a plurality of telescoping cylinders whose leading or trailing end is closed and which are extended by applied internal pressure in the tubular or some mechanical means. The tubular is expanded from its interior with the cylindrical telescoping members still extended. The cement is pushed all around the tubular due to the centralizers. After the cement is delivered the expansion of the tubular pushes the telescoping members into the borehole wall.

  • Publication number: 20040031615
    Abstract: In one variation, a tool is disclosed that can run cladding into casing where the cladding interior is closed off by opposed cup seals and access to the volume between the cup seals exists through the tool body. “Cladding” comprises sleeves, scrolls, casing, tubing and liner strings. Pressure is applied to the interior of the cladding to expand it into gripping and sealed contact with the casing. An exterior gripping surface can be provided on the cladding to enhance grip upon expansion. The tool can be repositioned to expand lengths of cladding including tubing or casing.
