Pore-scale wettability characterization in mixed-wetsandstones using dynamic laboratory micro X-raytomography Universiteit Gent
Multiphase flow is strongly influenced by the wettability of the porous medium. Conventionally, wettability is quantified by the contact angle between the fluid-fluid interface and the solid surface. Recent attempts to measure contact angles directly (AlRatrout et al., 2017; Scanziani et al., 2017) and indirectly (Blunt et al., 2019) from micro X-ray tomographic images have proven to be challenging due to the scale-dependent and hysteretic ...
