Patent number: 6918440Abstract: 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.Type: GrantFiled: April 16, 2003Date of Patent: July 19, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Virgilio Garcia-Soule, Timothy R. Carlson, Chuck MacPhail, Imre I. Gazda

Patent number: 6267180Abstract: 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.Type: GrantFiled: August 25, 1998Date of Patent: July 31, 2001Assignee: Halliburton Energy Services, Inc.Inventors: Imre I.
