Patent number: 11365605Abstract: A downhole tool includes a tubular having an outer surface and an inner surface defining a flowbore having a longitudinal axis, and a backpressure valve arranged in the flowbore. The backpressure valve includes a flapper valve having a first side and an opposing second side pivotally mounted to the inner surface to selectively extend across the flowbore and a locking system mounted to the inner surface in the flowbore and snap-fittingly engageable with the flapper valve. The flapper valve is pivotable between a first position, wherein the flapper valve is free to pivot relative to the inner surface, and a second position, wherein the flapper valve is pivoted away from the flowbore and locked open by the locking system such that the first side forms part of the flowbore.Type: GrantFiled: June 2, 2020Date of Patent: June 21, 2022Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Larry Thomas Palmer, Erik Van Steveninck, Erik Vilhelm Nordenstam, Eric Anders Erickson, Scott Bigrigg

Patent number: 11215026Abstract: A downhole tool includes a tubular having an outer surface and an inner surface defining a flowbore having a longitudinal axis and a backpressure valve arranged in the flowbore. The backpressure valve includes a flapper valve including a hinge end, a cantilevered end, a first side and an opposing second side pivotally mounted to the inner surface at the hinge end to selectively extend across the flowbore, and a locking system mounted to the inner surface adjacent to the hinge end of the flapper valve in the flowbore. The flapper valve is pivotable between a first position, wherein the flapper valve is free to pivot relative to the inner surface between an open configuration and a closed configuration, and a second position, wherein the hinge end of the flapper valve activates the locking system to lock the flapper valve in the open configuration.Type: GrantFiled: June 2, 2020Date of Patent: January 4, 2022Assignee: BAKER HUGHES OILFIELD OPERATIONS LLCInventors: Larry Thomas Palmer, Erik Van Steveninck, Erik Vilhelm Nordenstam, Eric Anders Erickson, Scott Bigrigg

Publication number: 20180058177Abstract: A tubular isolation system is operably connected with a movable member that selectively enables or disables the isolation system at least one time. In an embodiment the movable member is actuated by flow or pressure against a spring bias with an indexing system to regulate movable member movement so that that two opposed positions are attainable. The movable member can be a sleeve with a flow passage therethrough. One way to shift the sleeve is to land a ball on a seat on top of the sleeve and apply a cycle of pressure against the bias so that a j-slot moves the sleeve between end positions. The safety device is dual flappers in one embodiment. The sleeve can also be moved with circulation flow through the tubing with returns coming up the annulus. Alternatively a restriction can be used that later disappears for production.Type: ApplicationFiled: August 23, 2016Publication date: March 1, 2018Applicant: BAKER HUGHES INCORPORATEDInventors: Scott A.
