Publication number: 20100064893Abstract: A method of separating a multiphase fluid, the fluid including a relatively high density component and a relatively low density component, that includes introducing the fluid into a separation region; imparting a rotational movement into the multiphase fluid; forming an outer annular region of rotating fluid of predetermined thickness within the separation region; and forming and maintaining a core of fluid in an inner region. Fluid entering the separation vessel is directed into the outer annular region and the thickness of the outer annular region is such that the high density component is concentrated and substantially contained within this region, the low density component being concentrated in the rotating core. A separation system employing the method is also provided. The method and system are particularly suitable for the separation of solid debris from the fluids produced by a subterranean oil or gas well at wellhead flow pressure.Type: ApplicationFiled: June 15, 2007Publication date: March 18, 2010Applicant: CAMERON INTERNATIONAL CORPORATIONInventor: Hans Paul Hopper

Publication number: 20090242490Abstract: A method is disclosed for separating a multiphase fluid stream comprising a heavier fluid component and a lighter fluid component, the method comprising causing the fluid to flow along a first helical flowpath, the first helical flowpath having a first pitch, the first helical flowpath being sufficiently long to establish a stabilised rotating fluid flow pattern for the stream causing the uniform rotating fluid to flow along a second helical flowpath, the second helical flowpath having a second pitch, wherein the second pitch is greater than the first pitch; and removing the lighter fluid from a radially inner region of the second helical flowpath. An apparatus for carrying out the method is also disclosed. The method and apparatus are particular suitable for the separation of oil droplets from water, especially from water for reinjection into a subterranean formation as part of an oil and gas production operation. The method and apparatus are conveniently applied on a modular basis.Type: ApplicationFiled: February 22, 2007Publication date: October 1, 2009Applicant: CAMERON INTERNATIONAL CORPORATIONInventor: Hans Paul Hopper

Patent number: 6725936Abstract: An underwater well system in which an initially vertical drilling riser conduit is fixed by a template at the seabed in a non-vertical orientation. Drilling is carried out through wellhead in the template which also includes a valve tree allowing the production fluid to be brought to the surface along a line separate from the drilling riser conduit. The template may be a junction template allowing several wells to be drilled from a single template, or allowing the template to be connected by one or more drilling conduits to further templates such that a wide area of the seabed can be covered for a single drilling riser conduit.Type: GrantFiled: October 28, 2002Date of Patent: April 27, 2004Assignee: Cooper Cameron CorporationInventor: Hans Paul Hopper

Patent number: 6601656Abstract: A method of drilling an offshore underwater well comprising the steps of installing a riser conduit so that it is substantially vertically supported at a production deck. The riser conduit deviates progressively further from the vertical with increasing sea depth, so that its end can be anchored at the seabed by a skid either at an oblique angle so that drilling into the seabed can be carried out at the oblique angle, or horizontally, so that the riser conduit can extend some considerable distance across the seabed before drilling is carried out.Type: GrantFiled: June 18, 2002Date of Patent: August 5, 2003Assignee: Cooper Cameron CorporationInventors: Hans Paul Hopper, David Garnham
