Method for preparing improved high temperature fracturing fluids

摘要

The present invention related to a method for fracturing subterranean formations including the steps of (a) providing a water source; (b) adding a crosslinking agent to said water source; (c) adding a polymeric component to said water to create a fracturing fluid; (d) pumping said fracturing fluid into said formation. The fluid may contain an acrylamide-acrylate copolymer and any suitable number of additives. The additives are preferably combined with the water source to form an additive stream, to which the polymer is later added.
