ABSTRACT:
A micellar acidic surfactant solvent composition of enhanced oil/organic solvency and method of preparing and using same. The oil solvency of a propoxylated/ethoxylated surfactant and alcohol micellar acidizing system is enhanced by controlling or selecting the molar ratio of alcohol to surfactant as a linearly increasing function of acid concentration. The oil solvency is further enhanced and selectively controlled by addition of an oil solvent (e.g., aromatic hydrocarbons, aromatic acid esters, ketones, CS.sub.2, etc.) to the micelle.
