ABSTRACT:
A method of fracturing a subterranean formation is shown in which the holding vessel used to hydrate the hydratable polymer is reduced in size or eliminated. The method includes preparing a base gel from a guar gum and adding a crosslinking system to the base gel to form a crosslinked aqueous gel. The preferred crosslinking system includes (1) zirconium lactate and (2) aluminum chlorohydrate. The crosslinking system allows the hydratable polymer to continue to hydrate in the presence of the crosslinker.
