The Effects of Displacement Rate and Wettability on Imbibition Relative Permeabilities
2005
SPE Annual Technical Conference and Exhibition
unpublished
A new dynamic network model is used to investigate the effects of displacement rate and wettability on imbibition relative permeability. The network geometry and topology is representative of Berea sandstone. In contrast to existing quasi-static network models where snap-off, the major pore-scale trapping mechanism in imbibition, is suppressed by contact angle alone, the dynamic model introduces displacement rate as an additional snap-off inhibiting mechanism. The network model is used to
