In-situ capillary pressure and wettability in natural porous media: Multi-scale experimentation and automated characterization using X-ray images.

Hypothesis: Geometrical analyses of pore-scale fluid-fluid-rock interfaces have recently been used for in-situ characterization of capillary pressure and wettability in natural porous media. Nevertheless, more robust techniques and multi-scale, well-characterized experimental data are needed to rigorously validate these techniques and enhance their efficacy when applied to saturated porous media.

Experiments And Image Analysis: We present two new techniques for automated measurements of in-situ capillary pressure and contact angle, which offer several advancements over previous methodologies.
