SOF3

The SOF3 is followed by a table with three columns, in which the first is the oil saturation (\(S_o\)), the second is the oil in water relative permeability (\(K_{row}\)), the third is oil in gas relative permeability (\(K_{rog}\)). The table must be terminated by a / or END. An example is reported below:

The largest oil saturation for which the oil in water relative permeability is zero is the oil in water critical saturation \(S_{owcr}\) (0.2 in the example), and the largest oil saturation for which the oil in gas relative permeability is zero is the oil in gas critical saturation \(S_{ogcr}\) (0.38 in the example). \(S_o\) must increase monotonically. \(K_{row}\) and \(K _{og}\) can be constant or increase as \(S_o\) increases. At the maximum oil saturation, \(K_{row}\) must be equal to \(K_{rog}\) or the software will return an error.
