摘要： A screen section has a valve assembly to control flow through it. The valve is open and has a closure spring held compressed by a shape memory material that responds to the presence of a specific well fluid or fluids so that its property changes to allow the spring to deliver the stored potential energy to the valve member to close it when the specific well fluid or fluids are detected. The preferred material is a shape memory polymer that, for example, is sensitive to the presence of water or methane and gets softer to release the potential energy source to operate the downhole tool.

摘要： A packer or bridge plug uses a sealing element made from a shape memory polymer (SMP). The packer element receives heat or other stimulus to soften the SMP while the element is compressed and retained. While so retained, the heat or other stimulus is removed to allow the SMP to get stiff so that it effectively seals a surrounding tubular. High expansion rates are possible as the softness of the material under thermal input allows it to be reshaped to the surrounding tubular or to the surrounding open hole from a smaller size during run in and to effectively retain a sealed configuration after getting stiff on reduction in its core temperature while longitudinally compressed. The SMP or equivalent material whose modulus is changeable can be covered on the outside, the inside or both with an elastic material that protects the SMP and enhances the seal in the wellbore and against the mandrel.

摘要： An isolation assembly for downhole injection use is described that features at least one isolation device mounted on a tubular so that when injection fluid changes the tubular temperature which can cause a length change in the tubular, an anchor for the tubular is provided to resist such a dimension change. The result is that the isolation device such as a packer can be left undamaged and retaining its sealing integrity. The anchor can be an inflatable or telescoping pistons disposed to grab in open hole. When using telescoping pistons, their placement on the liner and their pattern can meet the desired locations where grip is enhanced. Use of cement inflatable anchors is contemplated as an alternative.

摘要： A screen that conforms to the borehole shape after expansion is disclosed. The screen comprises a compliant outer layer that takes the borehole shape on expansion. The outer layer is formed having holes to permit production flow. The material that is selected preferably swells with prolonged contact to well fluids to further close off annular gaps after expansion. In an alternative embodiment, the screen is not expanded and the swelling of the material alone closes off annular gaps. The outer sleeve is placed over the screen and the screen is placed on a base pipe and initially expanded from within the base pipe to secure the components of the screen assembly for running downhole, while minimizing or eliminating any welding among the layers. A variety of expansion tools can be used to expand the screen or screens downhole.

摘要： Composite tubulars that have not been polymerized and are thus flexible enough to be coiled are delivered into a wellbore and expanded. The expansion occurs from an external catalyst such as heat or releases the internal catalyst and allows the expanded tubular to become rigid. Optionally, healing agents can be imbedded in the tubular wall to be released to seal subsequently forming cracks.

摘要： An expanding screen has an associated spirally wrapped exterior control line. The control line rests in a spiral trough made up in an exterior perforated jacket. The trough can be made by a pair of ridges disposed substantially parallel to each other or by an ordered spacing of raised dimples in the outer perforated jacket to create spiral troughs. At the screen connections centralizers having a spiral path or paths within can serve a dual function of locating the screen prior to expansion and protecting the control line in the joint area. A fiber optic cable can be placed in the control line.

摘要： The present invention allows a well to be produced through a screen without the need for a gravel pack. This is accomplished by the placement of an expandable screen that can move radially outwardly when placed at the desired location against the wellbore and be porous enough with sufficient open area to allow production from the formation. The screen is placed in the desired location by using coiled tubing which can be preperforated for a support for the screen. The screen is protected during delivery to the desired location in the wellbore by providing a disposable or removable outer cover which can be disposed of after proper location on the screen in the wellbore.

摘要： The invention involves an assembly, specifically beneficial in deviated well-bores, which allows running into the wellbore with the complete completion assembly. The completion assembly includes one or more screens which may be pre-packed. Initially, a material which sets to form a permeable mass is deposited in the annular space outside the screens. After such material is deposited, cement or other sealing material is pumped into the annular space above the screens to complete the completion process. As a result, in one trip the deviated wellbore is completed with the permeable material deposited outside the screen or screens and cement being disposed in the annular space above the permeable material. Production can then begin.
