ABSTRACT:
A gel fluid for treating a subterranean formation penetrated by a well bore including an aqueous liquid, an organic gelling agent and at least about 0.05% by weight, based on the weight of the aqueous liquid, of a broken gel fragment stabilizer. The gel fluid can optionally include crosslinking agents, proppant materials, pH buffers and other components. The broken gel fragment stabilizer is a dialkyl sulfosuccinate that has dispersing properties sufficient to diminish the propensity of broken gel fragments formed when the gel fluid breaks to agglomerate. Also provided is a method of treating a subterranean formation penetrated by a well bore. The inventive gel fluid and method are particularly suitable for fracturing a subterranean formation to stimulate the production of hydrocarbons therefrom.
