A method is provided for selecting the optimum concentration of inhibitors such as soluble salts to effect maximum clay swelling and dispersion inhibition in an aqueous fluid of water-swellable, argillaceous materials including clays as exemplified by bentonite and argillaceous sediments, such as shales, encountered in drilling operations. In this method filtration measurements are first taken to develop a filtration parameter from which the optimum inhibitor concentration is readily determined.
