The disclosure concerns a method and apparatus for repairing or structurally
reinforcing an oil and gas well tubular member, or an assembly of tubular members.
The assembly to be repaired can include a smaller diameter inner flow conveying
conduit (or production tubing) and a larger diameter concentrically placed surface
casing, providing an annulus in between the production tubing and the surface casing.
A third casing pipe of largest diameter, the drive pipe is placed around the surface
casing string. Other "conductor" casing pipes can be positioned around the surface
casing inside the drive pipe. Part of the surface casing string (or other conductor
pipe) can suffer damage due to corrosion. A sleeve or repair member is placed around
the casing string or other tubular member at a damaged portion.
