Another well screen assembly includes a filter portion and a flow resistance device which decreases a resistance to flow of fluid in response to a predetermined stimulus applied from a remote location. Yet another well screen assembly includes a filter portion and a valve including an actuator having a piston which displaces in response to a pressure differential to thereby selectively permit and prevent flow of fluid through the valve.Type: GrantFiled: December 18, 2007Date of Patent: July 2, 2013Assignee: Halliburton Energy Services, Inc.Inventors: William M. Richards, John C. Gano

Publication number: 20130161024Abstract: A downhole fluid flow control system (100). The downhole fluid flow control system (100) includes a flow control component (122) having an internal flow path (134) and a temporary sealing substance (136) disposed within the internal flow path (134). During installation of the downhole fluid flow control system (100) in a well, the temporary sealing substance (136) prevents fluid flow through the flow control component (122), which prevents plugging or clogging of the internal flow path (134). After installation, the temporary sealing substance (136) degrades when exposed to a water source in the well, which enables fluid flow through the flow control component (122) and thus proper operation of the fluid flow control system (100).Type: ApplicationFiled: August 13, 2012Publication date: June 27, 2013Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventor: Stephen Michael Greci

Publication number: 20130153246Abstract: Wellbore devices for use in filtration, wellbore isolation, production control, lifecycle management and wellbore construction may include at least a first and a second shape-memory material each having an altered geometric position and each an original geometric position. Each shape-memory material may be held in the altered geometric run-in position at a temperature below glass transition temperature (Tg), where the Tgs and/or the respective slope changes of the first and second shape-memory materials are different. Optionally the shape-memory materials may be crosslinked polymers where the crosslinked polymers have different crosslinking ratios from one another. Once the wellbore device is in place downhole and the first and second shape-memory materials are subjected to temperatures above their Tgs, the materials will deploy to recovered geometric positions at or near their original geometric positions to perform their filtration, isolation, control or other function.Type: ApplicationFiled: January 25, 2013Publication date: June 20, 2013Applicant: BAKER HUGHES INCORPORATEDInventor: Baker Hughes Incorporated

Patent number: 8439108Abstract: Degradable polylactic or polyhydroxyalkanoate polymers may be used to viscosify aqueous fluids for use in wells, Sand control screen or liner can be coated with a solid degradable polymer during placement in a well. Mechanical changes or flow changes in a well can be caused by solid degradable polymer that changes physical properties after it is placed in a well. Parts of devices or entire devices can be made of solid degradable polymer that converts to a fluid after selected times in an aqueous environment in a well.Type: GrantFiled: July 6, 2012Date of Patent: May 14, 2013Inventor: Claude E. Cooke, Jr.

Publication number: 20130112400Abstract: A wellbore screen including: an apertured base pipe; an intermediate filtering layer including a plurality of metal fibers wrapped helically around the apertured base pipe and a fluid tracing filament wrapped helically about the apertured base pipe, the fluid tracing filament including a filament structure and a tracer carried by the filament structure, the tracer being entrainable in produced fluids in a wellbore environment; and an outer apertured shell over the intermediate layer. A method for producing a wellbore screen, the method comprising: forming a filter tube by wrapping an intermediate layer, including a metal wool fiber strip and a fluid tracing filament, about an apertured base pipe in a helical arrangement under tension; positioning the filter tube within the long bore of an outer apertured sleeve; and securing the outer apertured sleeve and the filter tube together.Type: ApplicationFiled: December 11, 2012Publication date: May 9, 2013Applicants: RESMAN AS, ABSOLUTE COMPLETION TECHNOLOGIES LTD.Inventors: ABSOLUTE COMPLETION TECHNOLOGIES LTD., RESMAN AS

Publication number: 20130105145Abstract: A wellbore assembly comprises a tubular member adapted to be connected to other tubular members, the tubular member having a side wall defining a hollow interior and an array of openings therethrough to permit material into the interior. A screening element extends about the tubular member over the array of openings to control the material that reaches the array of openings. A stress relieving arrangement associated with the screening element permits relative movement between the screening element and the tubular member to absorb stress build-up within the screening element whether due to mechanical or temperature induced forces that would tend to distortion the screening elements. In a preferred arrangement, the wellbore assembly serves to maintain solids control in production wells while accommodating stresses and strains that occur within the tubular members in those wells.Type: ApplicationFiled: September 7, 2012Publication date: May 2, 2013Inventors: Subodh Gupta, Simon Gittins

Patent number: 8430174Abstract: A well tool for use with a subterranean well can include an elongated passageway and a plug which prevents fluid communication through the passageway for a predetermined period of time. The plug can including an anhydrous boron compound, whereby the predetermined period of time is determined by a length of the anhydrous boron compound. A method of operating a well tool in conjunction with a subterranean well can include exposing an anhydrous boron compound to an aqueous fluid, with the anhydrous boron compound being included in a plug which prevents fluid communication through a passageway of the well tool. The well tool can be operated in response to fluid communication being permitted through the passageway a predetermined period of time after the exposing step.Type: GrantFiled: September 10, 2010Date of Patent: April 30, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Luke W.
