Abstract: A method of sealing casing or liners in a wellbore is described. The stands of casing or liner receive a jacket bonded to the outer surface. Preferably, the jacket is a rubber compound bonded to the outer wall. The formulation responds to well fluids to swell at a predetermined rate. The casing or liner can also be expanded with a swage preferably prior to the onset of significant jacket swelling. Packers and sealing hangers can be optionally added at the extremes of the casing or liner string to further secure against channeling between adjacent formations.

Abstract: 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.

Abstract: Drilling a well to total depth without tripping the bit out of the hole despite encountering a troublesome zone is made possible by using a memory based composite material delivered with the drill pipe or advanced over it, as needed. The material can be activated as a troublesome zone is encountered and assumes as former configuration that places it in sealing relation to the troublesome zone in the bore hole while spacing it from the drill pipe so as to allow resumption of drilling with the troublesome zone isolated.

Abstract: 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.

Abstract: A packer or bridge plug uses a sealing element made from a shape memory polymer (SMP). The packer element receives heat to soften the SMP while the element is compressed and retained. While so retained, the heat is removed to allow the SMP to get stiff so that 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 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.

Abstract: 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.
