Abstract
A patch for placement in a wellbore and associated methods includes a longitudinal member and an anchor that is radially expanded to engage the wall of the borehole to secure the patch against axial and radial movement. The anchor is set using a running tool that radially expands the anchor and the longitudinal body. The anchor may include one or more elements that can be securely engaged within the wellbore. The longitudinal member and/or the anchor may include a sealing element to provide a seal between the wellbore inside and the earth formation surrounding the wellbore.
