Patent number: 7201232Abstract: An isolation string having an upper packer and an isolation pipe in mechanical communication with the upper packer, the isolation pipe comprises an operable valve and an object activated valve. An object holding service tool is adapted to release an object to activate the object activated valve. A method of running-in an isolation string, comprising an operable valve and an object activated valve, with an object holding service tool having an object held therewith; setting the isolation string in the casing adjacent perforations; pressurizing the object to cause a release from the object holding service tool, whereby the object travels to the object activated valve; closing the object activated valve with the released object; and withdrawing the object holding service tool from the well.Type: GrantFiled: November 13, 2003Date of Patent: April 10, 2007Assignee: BJ Services CompanyInventors: Dewayne M. Turner, Donald H. Michel, Marvin Bryce Traweek, Richard J. Ross, Floyd Romaine Bishop, Gregg W. Stout

Patent number: 7150326Abstract: The present invention provides a bi-directional ball seat and method of use. In at least one embodiment, the present invention provides a fluid control system that includes a radial protrusion that can be selectively engaged and disengaged upstream and/or from a ball seat. For example, a ball can be placed in a passageway, engaged with a downstream ball seat, and the radial protrusion radially extended into the passageway distally from the seat relative to the ball. A reverse movement of the ball is restricted by the active radial movement of the radial protrusion into the passageway. The control system can be used to control a variety of tools associated with the well. Without limitation, the tools can include crossover tools, sleeves, packers, safety valves, separators, gravel packers, perforating guns, decoupling tools, valves, and other tools know to those with ordinary skills in the art.Type: GrantFiled: March 27, 2006Date of Patent: December 19, 2006Assignee: BJ Services CompanyInventors: Floyd Romaine Bishop, Marvin Bryce Traweek, Richard J. Ross, David J. Walker, Dewayne M. Turner

Patent number: 6981551Abstract: The present invention provides a return port cover that can close and open a return port separate from tubing movement caused by stretching or contracting under stress or other induced pipe movement from downhole conditions. For example, the return port cover can assist in preventing pack “fluffing” by preventing unintended fluid communication through an associated downhole tool regardless of the position of a circulating valve means. The return port cover can be biased, so that in one position it closes the port and in another position opens the port based on relative tubing placement at different portions of the fracturing operation or other well treatment operations.Type: GrantFiled: July 7, 2003Date of Patent: January 3, 2006Assignee: BJ Services CompanyInventors: Dewayne M.
