Abstract
Scale inhibitor is added to a cross-linked fracturing fluid as an integral part of the fracturing fluid. Preferred fracturing fluids are borate cross-linked and the preferred scale inhibitor is polyacrylate. In another embodiment of this invention, the fracturing fluid is prepared by adding a scale inhibitor to a fracturing fluid at a pH of between 8.5 and 10.5. In a third embodiment, the fracturing fluid prepared above is used to fracture subterranean formations. In a fourth embodiment, the fracturing fluid is used to pressurize a subterranean formation to break scale near the hydrocarbon wellbore.
