    摘要: The present invention provides methods of preparing and using viscous gelled well treating fluids devoid of insoluble gelling agent residue and compositions. A viscous gelled treating fluid composition devoid of insoluble gelling agent residue basically comprises water, a hydrated gelling agent and the water insoluble residue therefrom, a base for raising the pH of the water so that the water insoluble residue is dissolved therein, and additional water to lower the amount of the gelling agent in the treating fluid relative to the amount of water therein and to lower the pH thereof.
