Patent number: 11713638Abstract: A retrieving tool for retrieving an annular hollow baffle member in a wellbore. The baffle member has an interior bore and radially outwardly-biased collet finger protuberances on an exterior thereof matingly engaging a correspondingly-dimensioned annular recess within a landing sub of a well casing of the wellbore. The retrieving tool has a tubular body and a plurality of radially-outwardly-extendable dogs thereon. The tubular body and the dogs are sized that, when the dogs are retracted, the retrieving tool is movable through the interior bore of the baffle member to a position below a lowermost thereof, and when the dogs are extended after the retrieving tool moves to said position, the dogs radially engageable with the landing sub and axially engageable with the lowermost of baffle member for pulling the baffle member uphole and disengaging it from the landing sub for retrieving the entirety of the baffle member.Type: GrantFiled: July 31, 2020Date of Patent: August 1, 2023Assignee: SC ASSET CORPORATIONInventors: David Nordheimer, Daniel Rojas

Patent number: 11713641Abstract: A system is described for forming a debris barrier downhole in a wellbore. The system may include a mandrel, a retrievable downhole tool, and a debris ring. The mandrel may be positionable within a wellbore. The retrievable downhole tool may be positionable around the mandrel to perform tasks downhole in the wellbore. The debris ring may include an expandable material positionable around the mandrel to form a debris barrier. The debris barrier may be formed in response to exposing the expandable material to wellbore fluid.Type: GrantFiled: March 30, 2021Date of Patent: August 1, 2023Assignee: Halliburton Energy Services, Inc.Inventors: Robert Travis Murphy, Samuel Martinez, Michael Linley Fripp, Roderick Brand Falconer

Patent number: 11713643Abstract: A packer assembly includes a mandrel and a packing element disposed about the mandrel. Upper and lower recovery sleeves are disposed about the mandrel and extend between the mandrel and respective upper and lower ends of the packing element. The upper and lower recovery sleeves each have a recovery profile embedded within the packing element. Upper and lower backup assemblies are movably disposed about the respective upper and lower recovery sleeves, adjacent to the respective upper and lower ends of the packing element. The packer assembly includes at least one release mechanism. When setting the packer assembly in a bore, the packing element is axially compressed between the upper and lower backup assemblies to contact the bore wall, and the upper and lower backup assemblies splay outwards. Upon release, the packing element and backup assemblies retract, thereby facilitating retrieval of the packer assembly from the bore.Type: GrantFiled: October 30, 2020Date of Patent: August 1, 2023Assignee: Weatherford Technology Holdings, LLCInventors: Michael Wilbert Mitchell, Gary Duron Ingram
