ABSTRACT:
An apparatus and method for wettability measurements are provided. The apparatus includes a surface having a pair of electrodes separated by an insulator affixed thereto. The electrodes are operable for supporting an oil film, and the may be immersed in a surfactant solution. Circuitry for measuring the complex impedance between the electrodes is coupled to the electrodes. The capacitive part of the complex impedance provides a measure of the oil thickness as it is removed by the surfactant solution. A rotating member is provided for agitating the surfactant solution thereby modifying the effectiveness of the solution in removing the film.
