- Trapping with fluid bypassing occurs due to channel geometry, where an oil drop can become trapped by the Jamin effect.
- The pore doublet model assumes oil is trapped when displacement proceeds faster in one pore than the other and assumes pores are water-wet with equal viscosities and densities of oil and water phases.
- EOR process efficiency includes displacement efficiency (microscopic) and volumetric efficiency (macroscopic), influenced by capillary forces, viscous forces, mobility ratio, and viscous gravity ratio.
