Patent ID: 8657002

Claim:
A method for treating a subterranean formation, comprising: injecting a fluid comprised of fibers and a carrier fluid into the formation; and forming fiber reaction products that do not precipitate in the presence of calcium or magnesium ions, wherein the carrier fluid comprises a polymer that is present in the fluid in a concentration between about 1.92 g/L (about 16 ppt) and about 3.6 g/L (about 300 ppt), and wherein the fibers are selected from the group consisting of substituted and unsubstituted lactide, glycolide, polylactic acid, polyglycolic acid, copolymers of polylactic acid and polyglycolic acid, copolymers of glycolic acid with other hydroxy-, carboxylic acid-, or hydroxycarboxylic acid-containing moities, copolymers of lactic acid with other hydroxy-, carboxylic acid-, or hydroxycarboxylic acid-containing moieties, and mixtures thereof.
