The additional variable considered can be the bottom elevation, a reference width, a shape coefficient, or a vector containing these or other geometric parameters

Steady-state two-phase relative permeability measurements in proppant-packed rough-walled fractures Adv. Water Resour. (IF 4.0) Pub Date : 2024-05-25 Panav Hulsurkar, Abdelhalim I.A. Mohamed, Maziar Arshadi, Yanbin Gong, Mohammad Piri
Understanding multiphase flow in fractures filled with minerals and proppants is vital in various subsurface applications. Limited experimental data have led to reliance on correlations lacking physical basis. We conducted experiments to characterize relative permeability in rough-walled fractures packed with unconsolidated porous media. We tested fractures packed with water-wet 40/70 sand (silica)
