  • Patent number: 9458694
    Abstract: A system and method for extending a slotted liner shoe is disclosed. According to one embodiment, a low density material is injected into a liner having a plurality of openings. The liner is suspended below a cemented casing in a wellbore of a well in a subterranean formation. The low density material extrudes through a lower portion of the liner into an annulus between the liner and the wellbore. A cement is circulated into the liner above the low density material. The cement extrudes through an upper portion of the liner into the annulus between the liner and the wellbore. Water is displaced from the wellbore, and a solid cemented casing string is formed at a desired depth.

  • Patent number: 9228427
    Abstract: A well completion method provides for monitoring of reservoir pressure and saturation levels for two reservoirs from a single monitoring well. The well completion extends vertically through an upper and a lower reservoir. The well is cased, cemented, and perforated across the lower reservoir. A cement free zone is formed by cementing the casing string within the wellbore above an external casing packer above the upper reservoir. The casing string is perforated to allow fluid from the upper reservoir to flow through the cement free zone. A tubing string is landed and set within the casing string. The tubing string is sealed above and below the perforation at the cement free zone to prevent communication between fluid from the upper reservoir and the lower reservoir. The upper reservoir is monitored at the cement free zone, and the lower reservoir is monitored below an end of the tubing string.

  • Patent number: 8162053
    Abstract: A elongated plunger assembly for pressurized, conduit-enclosed travel utilized in recovery of hydrocarbon deposits in a ground penetrating oil or gas well. The plunger comprises an elongated mandrel, a plurality of radially movable curvilinear wear pads circumferentially disposed adjacent each end of the elongated mandrel, a pad-edge retaining housing extending on at least one end of the elongated mandrel to enclosably retain the longitudinally distal end of a circumferential array of wear pads onto the mandrel, and a centrally disposed wear pad securement ring arrangement to permit release of a worn wear pad, replacement of the worn wear pad at an inner longitudinal edge thereof, thus to permit simple field-accessable removal and replacement of any particular “conduit-worn” “wear” pad from the mandrel of the plunger.

  • Patent number: 8151895
    Abstract: Systems and methods for patching a desired section of wellbore casing or another tubular member. A patch assembly is provided which includes a tubular patch sub which is radially surrounded by an inflatable boot. A setting tool is used to set the patch assembly within the casing. The setting tool includes a heated barrel that contains eutectic material in liquid form. When actuated from the surface, eutectic material is flowed from the setting tool to the boot of the patch assembly. The eutectic material inflates the boot to secure the patch sub at a desired location within the wellbore.

  • Patent number: 8074722
    Abstract: A technique for securing a subsea well that has had some of its components damaged as a result of a storm or other catastrophic event. The techniques utilizes a casing head assembly that may secured to the casing of the damaged well by tightening a plurality of set screws to drive slips into the casing. The casing head assembly may also comprise a tubing hanger. Tubing head set screws may then be tightened to activate the tubing hanger to secure the production tubing to the casing head. The casing head assembly may also comprise a latch-lock connector that may be secured to the casing head by stabbing the latch-lock connector into the casing head and rotating the connector approximately one-quarter turn. A corrosion cap may then be secured to the latch-lock connector to cover the end of the production tubing.
