Patent number: 8118106Abstract: In one embodiment, a flowback tool for running a tubular string into a wellbore includes a tubular housing having a bore therethrough and a tubular mandrel. The mandrel: has a bore therethrough in communication with the housing bore, is longitudinally movable relative to the housing, is torsionally coupled to the housing, and has a threaded coupling for engaging a threaded coupling of the tubular string. The flowback tool further includes a nose: longitudinally coupled to the housing, operable to receive an end of the tubular string, and including a seal operable to engage a surface of the tubular string, thereby providing fluid communication between a bore of the tubular string and the mandrel bore. The flowback tool further includes an actuator operable to move the mandrel and the nose longitudinally relative to the housing for engaging and disengaging the tubular string.Type: GrantFiled: March 11, 2009Date of Patent: February 21, 2012Assignee: Weatherford/Lamb, Inc.Inventors: Jimmy Duane Wiens, Joseph Ross Rials, Raleigh Fisher, Eric T. Johnson

Patent number: 6950906Abstract: A method of operating a cache comprises the steps of reading first information from a tag memory for at least two cache lines; reading second information from the tag memory for at least two cache lines; writing third information to the tag memory updating the first information; comparing (i) an address of the tag memory associated with the step of reading the second information with (ii) an address of the tag memory associated with the step of writing the third information and, in response, selectively replacing the second information with the third information; and writing, after the step of comparing, fourth information to the tag memory updating the second information.Type: GrantFiled: December 13, 2002Date of Patent: September 27, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Robert F. Krick, Duane A. Wiens

Patent number: 6915396Abstract: The invention describes a system for and a method of creating and using dependencies to determine the order of servicing transaction requests in a multiple queue environment. When more than one outstanding transaction affects the same memory location, dependencies are established to ensure the correct sequencing of the competing transactions. In a preferred embodiment the dependency is configured to ensure that, as each request is inserted, other outstanding requests are checked to determine if the same memory location is accessed. If the same memory location is affected, a dependency is created which ensures the youngest queue entry which is present at the time the check is made occurs before the present outstanding request.Type: GrantFiled: May 10, 2001Date of Patent: July 5, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Duane A Wiens, Robert F. Krick
