HYDROPHOBICALLY MODIFIED POLYMER FOR THERMALLY STABILIZING FRACTURING FLUIDS

摘要

A method for treating a zone of subterranean formation is provided. The method includes the steps of: (a) forming a treatment fluid including: (i) water; (ii) a viscosity-increasing agent selected from the group consisting of water-soluble polysaccharides, water-soluble derivatives thereof, and any combination of the foregoing; (iii) a crosslinker for the viscosity-increasing agent; (iv) a hydrophobically modified water-soluble polymer; wherein the viscosity-increasing agent is not a hydrophobically modified polymer; and (b) introducing the treatment fluid into a zone of a subterranean formation, wherein the zone has a design temperature of equal to or greater than 350 °F.
