Pore-Level Influence of Contact Angle on Fluid Displacements in Porous Media new

H. Ali Akhlaghi Amiri[1]
[1]University of Stavanger, Stavanger, Norway

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability ... Read More
