Optical microscopy was used to measure depth-averaged oil distribution in a quasi-monolayer of crushed marble packed in a microfluidic channel as it was displaced by water. By calibrating the transmitted light intensity to oil thickness, we account for depth variation in the fluid distribution. Experiments reveal that oil saturation at water breakthrough decreases with increasing Darcy velocity, $$U_{\text {w}}$$Uw, between capillary numbers $$\text {Ca} = \mu _{\text {w}} U_{\text {w}}/\sigma… CONTINUE READING
