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.
