Patent number: 11230910Abstract: A downhole flow control device comprises a body locatable within a wall of a tubular, wherein the body defines a flow path therethrough to accommodate flow in reverse first and second directions between internal and external locations of the tubular in use. The downhole flow control device further comprises a regulator member mounted within the body and being moveable between first and second positions in accordance with flow direction through the body. The regulator member is locatable in the first position during flow through the body in the first direction to provide a first restriction to flow. The regulator member is locatable in the second position during flow through the body in the second direction to provide a second restriction to flow.Type: GrantFiled: January 30, 2018Date of Patent: January 25, 2022Assignee: SWELLFIX UK LIMITEDInventors: Ismarullizam Mohd Ismail, Annabel Green, Oliver Webster, Damien Gerard Patton, Stephen Garden

Patent number: 10155999Abstract: A method for manufacturing a metal structure (130) for use in a downhole assembly comprises plastically deforming at least a portion of the metal structure (130); and heating at least the deformed portion of the metal structure to a temperature below its critical and/or transformation temperature. An assembly for performing the method comprises a production fixture (370) configured to receive the metal structure (130), wherein the production fixture is adapted to undergo heating to a temperature below and/or up to the critical and/or transformation temperature of the metal structure. By heating at least the deformed portion of the metal structure to a temperature below its critical and/or transformation temperature, the metal structure may undergo stress relief, which may help prevent undesirable movement of deformed portion, e.g. collet fingers of a catching apparatus, against the direction of deformation after impact(s) and/or shock(s) from moving objects, in use.Type: GrantFiled: March 14, 2014Date of Patent: December 18, 2018Assignee: Weatherford Technology Holdings, LLCInventor: Oliver Webster
