Title: Porous tubular structures and a method for expanding porous tubular structures

Patent ·
OSTI ID:1531795

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.
