ABSTRACT:
An improved method and composition for reducing the production of sludge when contacting a subterranean formation containing oil which is subject to sludging with an aqueous acid solution. An anti-sludging agent such as a quaternary ammonium salt of a fatty amine, and one or more other additives are combined with the aqueous acid solution along with a dispersing agent which forms the aqueous acid solution and additives into a long-term homogeneous composition.
