Detailed Description of the IUustrative Embodiments An apparatus and method for repairing an opening in a damaged section of a weUbore casing within a subterranean formation is provided. The apparatus and method provides a system for repairing an opening in a damaged section of a weUbore casing within a subterranean formation in which a tubular member is radiaUy expanded into contact with the weUbore casing. The physical connection between the radiaUy expanded tubular member and the weUbore casing is preferably compliant and permits movement of the radiaUy expanded tubular member relative to the weUbore casing in at least the longitudinal direction. In this manner, the radially expanded tubular member is capable of absorbing a wide range of loading conditions. Referring initiaUy to Fig. 1, a weUbore 100 positioned within a subterranean formation 105 includes a preexisting casing 110 that traverses a producing formation 115. The portion of the casing 110 that traverses the producing formation 115 includes a damaged section 120. As wiU be recognized by persons having ordinary skill in the art, the damaged section 120 may be caused by, for example, structural instabilities in the producing formation 115 such as, for example, subsidence that can cause buckling of the weUbore casing 110.
Referring to Figs. 2 and 3, in order to repair the damaged section 120 of the weUbore casing 110, a conventional milling device 125 is then inserted into the weUbore casing 110. The milling device 125 is then used to remove at least a portion of the damaged section 120 of the weUbore casing 110 and thereby form an opening 130 in the weUbore casing 110.
Referring to Fig. 4, an apparatus 200 for repairing the opening 130 in the weUbore casing 110 may then be positioned within the weUbore casing proximate the opening in the weUbore casing. The apparatus 200 includes a tubular support member 205 having a longitudinal passage 210 and a transverse passage 215 that is coupled to an expansion cone 220 having a longitudinal passage 225 that is fluidicly coupled to the longitudinal passage 210. The expansion cone 220 is at least partiaUy received within an expansion cone launcher 230 that includes a thin-walled annular member 235 and a shoe 240 having an exhaust passage 245. An expandable tubular member 250 extends from the expansion cone launcher 230 that includes upper and lower sealing members 255a and 255b affixed to the exterior surface of the expandable tubular member. A sealing cup 260 is attached to the exterior surface of the tubular support member 205 for preventing foreign materials from entering the interior of the expandable tubular member 250.

As illustrated in Fig. 4, during placement of the apparatus 200 within the weUbore casing 110, fluidic materials displaced by the apparatus 200 are conveyed through the longitudinal passages 210 and 225 to the transverse passage 215. In this manner, surge pressures during the placement of the apparatus 200 within the weUbore casing 110 are minimized. Furthermore, as illustrated in Fig. 4, the apparatus 200 is preferably positioned with the tubular member 250 in opposing relation to the opening 130 in the weUbore casing 110. In this manner, the upper and lower seafing members 255a and 255b may engage portions of the weUbore casing 110 above and below the opening 130 after radiaUy expanding the tubular member 250.
As illustrated in Fig. 5, the transverse passage 215 may then be closed and fluidic materials injected into the apparatus 200 through the longitudinal passage 210. In this manner, any blockages within any of the passages 210, 225, and 245 may be detected by monitoring the operating pressure whereby an increase in operating pressure above nominal, or predetermined, conditions may indicate a blockage of one of the passages. As illustrated in Fig. 6, a plug 265 or other conventional stop member may then be introduced into the fluidic materials injected into the apparatus 200 through the passage 210, and the plug 265 may be positioned within the passage 245. In this manner, the passage 245 may be sealed off. Thus, continued injection of fluidic materials into the apparatus 200 through the passage 210 may thereby pressurize a region 270 below the expansion cone 220.
As illustrated in Fig. 7, continued pressurization of the region 270 causes the expansion cone 220 to radiaUy expand the expandable tubular member 250 off of the expansion cone. In this manner, the upper and lower seafing members 255a and 255b preferably engage the interior waUs of the weUbore casing 110 above and below the opening 130 thereby sealing off the opening. In a preferred embodiment, during the radial expansion process, the tubular support member 205 is raised out of the weUbore 100.
As illustrated in Fig. 8, the shoe 240 may then be removed using a conventional milling device. In this manner, exploration and production of subterranean regions beyond the opening 130 in the weUbore casing 110 may be conducted.
In several alternative embodiments, the upper seafing member 255a or the lower seafing member 255b are omitted from the tubular member 250. In this manner, the radiaUy expanded tubular member 250 is permitted to float relative to the weUbore casing 110. Furthermore, in this manner, relative longitudinal and/or transverse movements of the sections of the weUbore casing 110 above and below the opening 130 may be optimaUy accommodated by the radiaUy expanded tubular member 250. Finally, in this manner, damage to the radiaUy expanded tubular member 250 that can be caused by longitudinal stresses, such as buckling, may be minimized or eliminated.
In another alternative embodiment, as illustrated in Fig. 9, the upper seafing member 255a and/or the lower seafing member 255b include internal sfip joints 300a and 300b in order to permit the radiaUy expanded tubular member 250 to float relative to the weUbore casing 110. In this manner, relative longitudinal and/or transverse movements of the sections of the weUbore casing 110 above and below the opening 130 may be optimaUy accommodated. Furthermore, in this manner, damage to the radiaUy expanded tubular member 250 that can be caused by longitudinal stresses, such as buckling, may be minimized or eliminated.
In a preferred embodiment, the seafing members 255a and 255b permit the radiaUy expanded tubular member 250 to move in the longitudinal direction while also maintaining a fluidic seal. In several alternative embodiments, the seafing members 255a and 255b are fabricated from a resilient material such as, for example, synthetic or natural rubber.
It is understood that variations may be made in the foregoing without departing from the scope of the invention. For example, the apparatus 200 may be used to repair, for example, a weUbore casing, a pipeline, or a structural support.
Although illustrative embodiments of the invention have been shown and described, a wide range of modification, changes and substitution is contemplated in the foregoing disclosure. In some instances, some features of the present invention may be employed without a corresponding use of the other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
