Publication number: 20080073080Abstract: A well packing system and method for operating a well packing system wherein an isolation string assembly has a lower circulation valve with lateral flow ports that are operated to an open position without the use of shifters on a wash pipe. The isolation string assembly is incorporated into a well packing assembly within a wellbore and includes an upper sleeve tool that provides selective production of fluids through the frac pack assembly. In addition, the isolation string includes a lower circulation valve having a sliding sleeve that is shiftable from an open position to a closed position upon receipt of a suitable pressure differential. This configuration is particularly valuable for permitting monitoring of pressure or other conditions in the annulus of the wellbore portion being packed during packing operations. Further, the lower circulation valve tool can be used to selectively allow fluid returns during the packing operation.Type: ApplicationFiled: September 13, 2007Publication date: March 27, 2008Applicant: Baker Hughes IncorporatedInventors: Thomas Corbett, Anderson Amaral, Kenneth MacDonald, William Triplett

Publication number: 20050103495Abstract: A gravel packing method and apparatus are described where to set the packer; a ball is dropped to a seat that it isolated from the effects of formation pressures when trying to set the packer. This is accomplished by isolation of the gravel pack outlet port when setting the packer and locating the ball seat in a position where the effects of formation pressure are irrelevant. Additionally, by positioning the evacuation ports above a seal bore in the screen extension during circulation or squeeze to deposit gravel and further putting check valves in the evacuation ports, the evacuation step after circulation or squeeze can be accomplished without having to reposition the crossover. The crossover is supported from the packer and movement of the crossover away and back to the support from the packer operates a valve to allow squeezing when the valve is closed and circulating and reversing out when the valve is open.Type: ApplicationFiled: November 17, 2003Publication date: May 19, 2005Inventor: Thomas Corbett
