Disclosed herein is an acid-in-oil emulsion composition comprising an emulsifying agent; a dispersion agent; a base oil; and an acid, wherein the acid-in-oil emulsion composition is substantially devoid of priority pollutants. Disclosed herein too is a method for treating a hydrocarbon-bearing formation comprising blending an emulsifying agent, a base oil and an acid to produce an acid-in-oil emulsion, the acid-in-oil emulsion being substantially devoid of priority pollutants; and discharging the acid-in-oil emulsion into a downhole hydrocarbon-bearing well formation, where the acid-in-oil emulsion is operative to stimulate hydrocarbon production.
