Surface energy and wetting behavior of reservoir rocks

- Investigated the surface energy of a reservoir rock using IGC.
- Examined the effect of moisture and temperature on their surface energetics.
- The surface interaction forces at the rock-fluid interface were quantified.
- Proposed a new approach for measuring the wettability index of a rock-fluid system.
- Wettability index scales from −1 (strongly oil-wet) to +1 (strongly water-wet).
