DETERMINING SURFACE WETTING OF ROCK WITH CHANGING WELL FLUIDS

摘要

Methods and apparatuses for determining surface wetting of a rock material with changing well fluids. In general the methods according to the invention include measuring electrical impedance spectroscopy ('EIS') for a system simulating downhole conditions for the wetting of a surface. Methods and apparatuses for making EIS measurements model double layer capacitance at a downhole surface in a well from which the nature and quantification of the wetting of the surface can be inferred.
