Expandable wellbore loss control patch

Abstract

A wellbore patching system includes a radially expandable tube member including a sheet wrapped in a spiral. The sheet includes a first circumferential edge and a second circumferential edge opposite the first circumferential edge and coupled to the first circumferential edge. The radially expandable tube member includes a hollow interior. The wellbore patching system includes a deployment tool including: a tool body; and a restraining device coupled to the tool body and configured to prevent radial expansion of the tube member when the tool body is positioned within the hollow interior of the tube member and the restraining device is applied to the tube member. The first circumferential edge is bent to form a first hook, the second circumferential edge is bent to form a second hook, and the first circumferential edge is coupled to the second circumferential edge by the first hook engaging the second hook.
