Patent ID: 8766641

Claim:
A method comprising the steps of: (A) obtaining or providing an apparatus comprising: (i) a container forming a chamber; (ii) a first surface exposed to or in the chamber, wherein the first surface is of a first rock material in contact with a first electrode; (iii) a second surface exposed to or in the chamber, wherein the second surface is of: (a) a second electrode, or (b) a second rock material in contact with the second electrode; wherein the first surface is electrically insulated from the second surface; (B) wetting at least the first surface with a first liquid phase of a first bulk fluid; (C) after the step of wetting, introducing a second bulk fluid into the chamber, wherein the second bulk fluid comprises a second liquid phase, and wherein the second liquid phase is immiscible with the first liquid phase; (D) applying a shear between the second bulk fluid in the chamber and at least the first surface; and (E) at least once during or after applying the shear, making an electrical impedance spectroscopy measurement between the first and second electrode.
