Patent number: 11536120Abstract: Described is a flow control device comprising a body locatable with a tubular and a flow regulator, housed within the body. The flow regulator defines a flow path through the body to accommodate flow between internal and external locations of a tubular in use. The flow regulator comprises a valve arrangement forming part of the flow path, and a biasing mechanism configured to urge the valve arrangement towards an open configuration from a restricted configuration in which fluid flow though the flow path is restricted. The biasing mechanism and the flow path through the flow control device are configured such that a differential pressure acting across the flow regulator, in excess of a particular threshold, moves the valve arrangement from the open configuration towards the restricted configuration in order to limit flow through the flow control device.Type: GrantFiled: June 19, 2019Date of Patent: December 27, 2022Assignee: SWELLFIX UK LIMITEDInventors: James Anderson, Annabel Green
