Abstract: A method for lining a portion of a casing affixed within a well bore a distance below an upper end of the well bore with a viscoelastic pipe having an upper end, a lower end, and an outer diameter greater than the inner diameter of the casing is provided. The outer diameter of the pipe is reduced so that the outer diameter of the pipe is less than the inner diameter of the casing. The reduced pipe is then lowered into the casing to a predetermined depth where the upper end of the reduced pipe is positioned a distance below the upper end of the well bore. The reduced pipe is then allowed to expand against the internal wall of the casing, thereby forming a fluid tight seal with the casing and effectively sealing any breaches in the casing. So that the outer diameter of the reduced pipe remains less than the inner diameter of the casing as the viscoelastic pipe is being passed down the casing, the reduced pipe is maintained in tension as the reduced pipe is being passed down the casing.
