Abstract: An expandable tubular to be used within geologic structures and a method of manufacturing thereof has a substantially tubular shaped member with an axis extending therethrough. The tubular member has one or more helical member formed within a wall of the tubular member, and the helical member may be defined about the axis of the tubular shaped member. Further, a plurality of elongated perforations are formed within the wall of tubular member, and the tubular member is compressible from a larger diameter to a smaller diameter. When compressed, the tubular member stores expansive energy within the wall, in which the tubular member may then expand back to a larger diameter when the expansive energy is released.
Abstract: An expandable tubular includes a plurality of leaves formed from sheet material that have curved surfaces. The leaves extend around a portion or fully around the diameter of the tubular structure. Some of the adjacent leaves of the tubular are coupled together. The tubular is compressed to a smaller diameter so that it can be inserted through previously deployed tubular assemblies. Once the tubular is properly positioned, it is deployed and coupled or not coupled to a previously deployed tubular assembly. The tubular is useful for all types of wells and boreholes.

Abstract: Expandable tubulars for use in geologic structures, including methods for expanding the expandable tubulars, and methods of manufacturing them, include the use of an expansive energy storage component, which provides a self-expanding feature for the expandable tubulars.
