To capture the surface ,properties, of the reservoir material, system wettability is modified in 10° contact angle increments to achieve oil-wet, mixed-wet, and water-wet systems. In addition to representative porous media, all testing is run at reservoir temperature, pressure, and ,fluid, flow rates.
