Computation of Three-Phase Capillary Pressure Curves and Fluid Configurations at Mixed-Wet Conditions in 2D Rock Images

Abstract: We present a three-phase, mixed-wet capillary bundle model with cross-sections obtained from a segmented 2D rock image, and apply it to simulate gas invasion processes directly on images of Bentheim sandstone after two-phase saturation histories consisting of primary drainage, wettability alteration and imbibition. We calculate three-phase capillary pressure curves, corresponding fluid configurations and saturation paths for the gas invasion processes and study the effects of mixed wettability and saturation h… Show more

“…In addition to methane, also liquid water (connate water and injected water/retained fracturing fluid) is present in shale nanopores (Li et al 2018;Xu et al 2017). When it comes to multi-phase transport in porous media, wettability-usually characterized by contact angle and surface tension-is a significant factor controlling fluid distribution and fluid flow (Zhou et al 2016). There is, however, limited research on the interactions of the various components of multi-phase transport mechanisms in nanoscale pores with roughness.…”

“…Pore network modelling is an efficient way to simplify the computational procedures to simulate multiphase flow at the pore scale. [13][14][15][16][17] A pore network model replaces the complex pore structures with a representative network of pore bodies connected by narrower restrictions called pore throats. Pore bodies and throats are assigned the corresponding geometrical properties, such as pore volume, length, inscribed radius, shape factor, etc.…”
