摘要： A valve (30) for a production liner (12) in connection with the extraction of oil and gas, arranged to automatically shut of the flow of fluid into the production liner (12) in the event of a gas break-through, whereby the valve (30) comprises a valve seating (32) containing at least one central inflow channel (34) and one or more outflow channels (36, 38) from the valve (30). The valve (30) is constructed with a curved design equal to the shape of the outer diameter of the production liner (12), and is placed on the outside of the production liner (12), and in that a rectangular shut off disk (40) with the same curving is arranged in the valve (30), in the flowing path of the liquid flow, to cause a high velocity flow over the shut off disk's surface (40a) against the valve seat (32), wherein the shut off disk (40) is adapted to seal against said valve seat (32) dependant on the differential pressure being produced by the viscosity of the passing flow. The invention also comprises a production liner containing a valve.

摘要： A method to monitor the integrity of a sand screen normally comprising: (i) directing at least one electromagnetic wave towards a sand screen under controlled conditions outside of a borehole; (ii)detecting at least one reflected or emitted electromagnetic wave from said sand screen in step (i) in order to produce at least one data measurement then (a) directing at least one electromagnetic wave towards the sand screen inside a borehole; and (b) detecting at least one reflected or emitted electromagnetic wave from said sand screen inside the borehole in order to produce at least one data measurement. The method normally emits and detects alternating magnetic fields/waves using an electromagnetic logging tool and can surprisingly provide useful data on the condition of sand screens in a borehole.

摘要： A first embodiment of the invention relates to a separator for separating sand and rock particles during the extraction of liquids or gases from rock bores. Said separator comprises a plurality of stacked, annular disks of a brittle hard material which disks are axially braced by means of a supporting structure and have at least three spacers on top which are evenly distributed across the circumference of the disks. The disks are stacked in such a manner that the spacers lie on top of each other and that a respective separating gap having a height of from 0.05 to 1 mm, preferably 0.2 to 0.5 mm separates the individual disks. A second embodiment of the invention relates to a separator for separating sand and rock particles during the extraction of liquids or gases from rock bores. Said separator comprises a plurality of stacked, sleeve-type elements of a brittle hard material which elements are axially braced by means of a supporting structure, the sleeve-type elements comprising slots having a slot width of from 0.05 to 1 mm, preferably 0.2 to 0.5 mm.

摘要： A downhole apparatus is described comprising a main body coupled with a well tubing and a swellable mantle disposed on the main body. The swellable mantle expands upon contact with at least one predetermined fluid, and the main body comprises at least one opening for fluid flow between an exterior of the main body and the bore. An insert permits the passage of fluid, through the swellable mantle, between the exterior of the apparatus and the opening. In one aspect of the invention a screen filters solids between the exterior of the apparatus and the bore, and a swellable mantle comprises a first region which allows the passage of fluid between the exterior of the apparatus and the main body and a second region, circumferentially adjacent the first region, which substantially prevents passage of fluid. Corresponding well completion and production methods are also described.

摘要： A sand control screen assembly (40) is operably positionable within a wellbore (48). The sand control screen assembly (40) includes a base pipe (42) having at least one opening (60) and an internal flow path (44). A swellable material layer (46) is disposed exteriorly of the base pipe (42). A fluid collection subassembly (50) is disposed exteriorly of the swellable material layer (46). The fluid collection subassembly (50) is in fluid communication with the internal flow path (44). A filter medium (62) is operably associated with the sand control screen assembly (40) and is disposed in a fluid path between the exterior of the sand control screen assembly (40) and the internal flow path (44). In response to contact with an activating fluid, radial expansion of the swellable material layer (46) causes at least a portion of the fluid collection subassembly (50) to contact the wellbore (48).

摘要： A flow control screen (100) includes a base pipe (102) having a blank pipe section (104) and a perforated section (106). A filter medium (112) is positioned around a portion of the blank pipe section (104). A housing (114, 118, 120, 122, 124) is positioned around another portion of the blank pipe section (104) and the perforated section (106). A deformable element (150) is positioned between the housing and a portion of the perforated section including at least one production port (108) but not including at least one closure port (110) to define a production path (154) between the production port (108) and the filter medium (112) such that application of a sufficient pressure to the closure port (110) acts on the deformable element (150) to deform the deformable element (150) to substantially close the production path (154).
