$Effect of surface roughness and lithology on the water–gas and water–oil relative permeability ratios of oil-wet single fractures$

Effect of surface roughness and lithology on the water–gas and water–oil relative permeability ratios of oil-wet single fractures

•Visual displacement experiments were conducted on the transparent replicas of seven fracture samples.•The effect of surface roughness on relative permeabilities of single fractures was clarified.•Fractures developed from less porous (larger grain) rocks yielded residual saturations in large pockets...
