Correlation of capillary number relationships for sandstone

OSTI ID:6498025
Capillary number relationships are presented for displacement of residual oil, and for displacement of oil which is initially continuous from water-wet sandstone having permeabilities which varied over about two orders of magnitude. It was found that the onset of mobilization could be correlated with sample permeability. Relationships between normalized reduced residual oil saturation and capillary number were correlated satisfactorily for different sandstones samples. Several applications of results to problems in tertiary oil recovery are discussed. 19 refs.
