Abstract
A method of forming a seal circumferentially about a liner having pre-formed openings that is positioned in a wellbore includes the steps of running a perforating device and a seal applicator into the slotted liner, the seal applicator carrying a sealing fluid and a pumping mechanism, creating an aperture through the slotted liner at the region by activating the perforating device and pumping the sealing fluid from the seal applicator through the aperture and circumferentially about the liner to form a sealing plug in the annulus between the slotted liner and the wellbore.
