Abstract
A novel technology (electrokinetics) is proposed to improve acidizing operations in penetrating formations, i.e., how to increase the penetration distance. Aqueous solutions of hydrochloric acid (usually 15%) are pumped into the carbonate formations to enlarge the pores and pre-existing fractures. However, the penetration distance of acid is very short. By applying D.C. current, one can drive the acid for long distances into the formation being acidized.
