20090242490 | Method and Apparatus for Fluid Separation - 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. | 10-01-2009 |
20100011557 | Flow Block - A method of manufacturing a flow block for use as a T-Block, tree block, manifold block or valve block, the method including: machining a main bore in a body; forming an opening in the body in a side wall of the main bore; providing an insert including a first bore intersecting with a second bore and being in fluid communication with each other; forming a substantially curved surface on at least part of the intersection between the first bore and the second bore; and inserting the insert into the opening, such that the first bore is substantially aligned with the main bore in order to provide a fluid flow path between the main bore and the second bore. | 01-21-2010 |
20100064893 | Separator and Method of Separation - 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. | 03-18-2010 |
20100288389 | Choke Assembly - 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. | 11-18-2010 |

20130001170 | Method and Apparatus for Fluid Separation - A method and apparatus are disclosed for separating a multiphase fluid stream that includes a heavier fluid component and a lighter fluid component. The fluid flows along a first helical flowpath with a first pitch. The first helical flowpath is sufficiently long to establish a stabilised rotating fluid flow pattern for the stream. The uniform rotating fluid also flows along a second helical flowpath, the second helical flowpath having a second pitch greater than the first pitch. The lighter fluid is removed from a radially inner region of the second helical flowpath. The method and apparatus are particularly 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. | 01-03-2013 |
