<p>A method of treating a borehole 3 which extends into a formation involves circulating a polymer 2 and a carrier in the borehole 3, the polymer 2 melting, fusing and/or curing by heat from the formation to produce a lining or liner at the wall of the borehole. The polymer may be an epoxy polymer and be in particulate form having a metal core (22, fig 3) and a polymer coating (21, fig 3) surrounding the core.</p> |
