Pore-scale imaging of multiphase flow at steady state for a Bentheimer sandstone


Segmented images for different fractional flows Origin Data

Images during imbibiiton at different fractional flows that were used for curvature measurements. total_porosity.raw is the segmented image for the entire porosity (phi_tot), including subresolution pores. This porosity needs to be used to calibrate brine saturation (micro porosity will contain brine in water wet systems). fw*.raw are the segmented images for different fluid fractions to compute curvature. To obtain brine saturation (Sw) for each fractional flow, please extract oil phase from fw*.raw images, compute the fraction (frac_oil), and use the following formula: Sw = (phi_tot-frac_oil)/phi_tot. Phase values for fw*.raw 1: oil phase; 2: brine phase; and 3: rock grain phase. Phase values for total_porosity.raw 1: macro pores; 2: micro_porosity (average porosity = 0.32); and 3: rock grain.
