Methods for the in-situ application of coating agent to production tubing within wellbores using plunger lift systems are provided herein. One method includes shutting in the wellbore, pressurizing the production tubing to displace fluids from the production tubing, and dropping a plunger from the surface into the production tubing such that the plunger travels toward the bottom of the production tubing until landing on a bumper spring. The method also includes pumping a predetermined amount of the coating agent from the surface into the production tubing such that the coating agent flows to the bottom of the production tubing and settles on top of the plunger and utilizing the differential pressure between the production tubing and the annulus to return the plunger and the coating agent to the surface, where the coating agent is applied to the inner diameter of the production tubing as it flows toward the surface.

A seamless tubular liner for repairing an underground or surface pipe is disclosed, including circumferential wefts consisting of slivers comprising a plurality of staple fibers bundled together, the slivers adapted to elongate through disentanglement of the bundled staple fibers when the seamless tubular liner is subjected to an inflation pressure such that the diameter of the tubular liner is able to expand to accommodate variations of diameter of the pipe being repaired.
