Treatment results in more than 180 wells offshore Louisiana indicate the self-generating mud-acid system developed by Shell is a useful tool for improving oil-well productivity. The self-generating mud acid--known as SGMA--is designed for slow, continuous generation of hydrofluoric (HF) acid after the fluid is placed at some depth in the formation. SGMA is a trademark of Shell Oil Co. (U.S. 3,828,854). In SGMA, generation of HF acid does not rely on the contact and chemical reaction between 2 separate fluids. SGMA is a family of systems which can be used at reservoir temperatures varying from 130/sup 0/ to 270/sup 0/F. Field work discussed was done in the range of 130/sup 0/ to 190/sup 0/F.
