Abstract
The present method forms a cross linked fracturing fluid using produced water. The produced water is a brine water having a TDS content of at least 45,000 mg/L. The produced water is mixed with a crosslinkable guar. The pH of the water is adjusted for hydration, if necessary, by adding acid prior to or with the addition of the guar to the produced water. The guar is allowed to hydrate in the water. A crosslinker is added and, if necessary, a base with or after the addition of the crosslinker, wherein the base is added to adjust the pH of the water for crosslinking.
