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.

Porous tubular structures and a method for expanding porous tubular structures

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.

Expandable tubulars for use in geologic structures

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.
