Patent number: 10450831Abstract: A choke assembly. In some embodiments, the choke assembly includes a choke element having a fluid flow passage therethrough. The choke element includes a cage having a plurality of apertures therethrough for the passage of fluid and a plug moveable with respect to the cage. The plug has an end surface that defines a boundary of the fluid flow passage through the choke and is moveable to open or close each of the apertures through the cage, whereby the flow of fluid through the cage is controlled. The apertures in the cage are disposed in a first portion and a second portion separated by a land. Each of the first and second portions has a least one aperture therein. The plug may be positioned with its end surface disposed to intersect the land, such that each aperture is fully open or fully closed to the flow of fluid.Type: GrantFiled: September 24, 2008Date of Patent: October 22, 2019Assignee: Cameron International CorporationInventors: Hans Paul Hopper, Derek Meek

Publication number: 20140150881Abstract: A choke assembly comprises an inlet (48) for a multiphase fluid stream, the stream comprising a first relatively heavy fluid phase and a second relatively light fluid phase; a first fluid outlet (116); a choke element (22) disposed between the inlet and the first fluid outlet operable to control the flow of fluid between the inlet and the first fluid outlet; a separation chamber (40, 114) disposed to provide separation of phases in the fluid stream upstream of the choke element; and a second outlet (118) for removing fluid from the separation cavity. The choke assembly is of particular use in the control of fluid streams produced from a subterranean well, in particular oil and gas produced from a subsea well.Type: ApplicationFiled: November 12, 2013Publication date: June 5, 2014Applicant: CAMERON INTERNATIONAL CORPORATIONInventors: HANS PAUL HOPPER, DEREK MEEK
