Phelps, C H; Sampath, K

A method is described for making an aqueous gel formed into a polysaccharide. The gel is used as a fluid medium in a subterranean formation for the production of hydrocarbonaceous fluids. The improvement comprises: mixing a substantially small amount of an alkali or alkaline earth metal hydroxide sufficient to cause gelation with a water soluble scleroglucan polysaccharide within a substantially effective time period where the hydroxide is contained in an aqueous solution in an amount of from about 1 to about 500 ppm which solution also contains a water thickening amount of the water soluble scleroglucan polysaccharide; and then complexing the polysaccharide with an amount of a water-soluble compound of a polyvalent metal ion.
