Impact of the scale factor on mobilization of residual oil: A laboratory experiment

Experimental data on residual oil mobilization in laboratory simulation of oil displacement by water demonstrate the impact of the scale effect on this process reflected in the value of residual oil mobilization and displacement thresholds. It is established that residual oil saturation decreases with an increase in the model size used. It is shown that the sizes of clusters of the trapped oil phase correlate with the size of the laboratory model.
