Title: APPARATUS AND METHODS FOR DETERMINING SURFACE WETTING OF MATERIAL UNDER SUBTERRANIAN WELLBORE CONDITIONS
Abstract:
Methods and apparatuses for determining surface wetting of metallic materials at downhole wellbore condition with fixed or changing well fluids are disclosed. In general, the methods according to the disclosure include carrying out an electrical impedance spectroscopy ("EIS") for a system simulating downhole conditions for the wetting of a surface by simultaneously dynamically moving electrodes exposed to the well fluid while measuring the changes in electrical characteristics between the electrodes.
