  • Patent number: 7775269
    Abstract: A communication tool (100) includes a housing (102) having recesses (110) and a set of axial locating elements (112) radially extendable through the recesses (110) and engageably positionable within a profile of a tubing retrievable safety valve (50). An anti rotation device (140) is radially outwardly extendable relative to the housing (112). The anti rotation device (140) operably engages the tubing retrievable safety valve (50) to substantially prevent relative rotation between at least a portion of the communication tool (100) and the tubing retrievable safety valve (50). A cutting tool (148) is radially outwardly extendable relative to the housing (102). The cutting tool (148) is operable to create a fluid passageway (150) between a non annular hydraulic chamber (60) and an interior the tubing retrievable safety valve (50).

  • Patent number: 7032672
    Abstract: A tubing retrievable safety valve (50) having a non annular hydraulic chamber (60) in a sidewall portion thereof is operable to received a communication tool (100) therein such that relative rotation between at least a portion of the communication tool (100) and the tubing retrievable safety valve (50) is substantially prevented. The communication tool (100) is operable to create a fluid passageway (150) between the non annular hydraulic chamber (60) and the interior of the tubing retrievable safety valve (50) by penetrating through the sidewall portion and into the non annular hydraulic chamber (60). Thereafter, when a wireline retrievable safety valve (44) is positioned within the tubing retrievable safety valve (50), hydraulic fluid is communicatable thereto through the fluid passageway (150).

  • Patent number: 6918440
    Abstract: One embodiment of the present disclosure describes a test assembly including an inflatable packer. An internal control sleeve controls flow of drilling fluid through an inflation port to inflate and deflate the packer. A shifting tool run on a slick line moves the sleeve. The packer has one end attached to an external sliding sleeve which moves upon packer inflation to expose a formation fluid port through which formation testing is performed. After testing and packer deflation, a circulation port may be opened to recover produced fluids up the drill string. A second sleeve controls flow through the circulation port and is controlled by a second shifting tool run on slick line. Other embodiments include a circulation assembly with a sliding sleeve opened and closed by one shifting tool to control circulation and the sliding sleeve itself and its operation.

  • Patent number: 6880641
    Abstract: A system for communicating hydraulic fluid to a wireline retrievable safety valve (44) comprises a tubing retrievable safety valve (50) having a non annular hydraulic chamber (60) in a sidewall portion thereof and a communication tool (100) that is selectively locatable within the tubing retrievable safety valve (50). The communication tool (100) creates a fluid passageway (150) between the non annular hydraulic chamber (60) and the interior of the tubing retrievable safety valve (50) by penetrating through the sidewall portion and into the non annular hydraulic chamber (60). Thereafter, when the wireline retrievable safety valve (44) is positioned within the tubing retrievable safety valve (50), hydraulic fluid is communicatable thereto through the fluid passageway (150).

  • Patent number: 6742595
    Abstract: A communication tool (100) for communicating hydraulic fluid through a tubing retrievable safety valve (50) is disclosed. The tool (100) has a first section (102) and a second section (132) that are initially coupled together. A set of axial locating keys (112) is operably attached to the first section (102) and is engagably positionable within a profile (62). A radial cutting device (148) is radially extendable through a window (152) of the second section (132). A circumferential locating key (140) is operably attached to the second section (132) and is engagably positionable within a pocket (66) of the safety valve (50) when the first and second sections (102, 132) are decoupled, thereby circumferentially aligning the radial cutting device (148) with the non annular hydraulic chamber (60).

  • Patent number: 6675891
    Abstract: An apparatus for gravel packing a production interval (42) of a wellbore (32) comprises first and second sand control screen assemblies (56, 58) connected downhole of a packer assembly (46) and a cross-over assembly (40) that provides a communication path (74) downhole of the packer assembly (46) for a gravel packing fluid and a communication path (92) uphole of the packer assembly (46) for return fluids. A wash pipe assembly (66) extends into the first and second sand control screen assemblies (56, 58) forming an annulus (84) therebetween. A valve (70) is positioned within the wash pipe assembly (66) in a location between the first and second sand control screen assemblies (56, 58). The valve (70) is actuatable from a closed position to an open position when the beta wave (100) is proximate the location of the valve (70).

  • Patent number: 6267180
    Abstract: The present invention provides a packer releasing tool for releasing a packer from a wellbore where the packer is coupled to a tubing string and has a releasing profile with a packer uphole shoulder and a packer downhole shoulder. The packer releasing tool preferably comprises a toplock assembly removably coupled to a downlock assembly. It also includes a toplock key that is movably coupled to the toplock assembly and that has a toplock key profile engageable against the packer releasing profile. Also present is a downlock lug that is movably coupled to the downlock assembly and that has a downlock lug profile engageable against the packer releasing profile. In one embodiment, the packer releasing tool has an outer diameter that is less than the inner diameter of the tubing string. This unique configuration allows the packer to be pulled without the need of first removing the production string.

  • Patent number: 6070672
    Abstract: In an oilfield wireline tool string, a self-contained downhole power unit is positioned at a designated working location and mechanical jars cut shear pins retaining an activating mandrel so as to displace a valve seat and open a mechanically actuated valve. This valve admits well pressure to a pressure-sensing switch in the downhole power unit to initiate its operation.
