Water-saturation profiles

Fig. 4.1.13 Calculated and measured water saturation profiles for a multi-rate primary drainage experiment on the Texas Cream limestone sample. Starting from the upper left, profiles correspond to times of 12, 22, 238, 500 and 696 min. (Reprinted with permission for [34]).

Equation 2.105 shows that Swp can be found by drawing a tangent to the fw versus Sw curve for the polymer solution from the point (Sw, fw) = (-Dp, 0), as shown in Figure 2.18. The water saturation profile is shown in Figure 2.19. The average wafer saturation is given by Eq. 2.106. 

FIGURE 2.21 Water saturation profile when a polymer flood is started at a high initial water saturation. 

A surfactant flood can recover the oil left from a waterflood. Sometimes, a surfactant flood is applied at the waterflood residual oil saturation, So . When a surfactant flood is started, Sorw, the water saturation profile is as shown in Figure 2.25. Corresponding to Figure 2.25, Figure 2.26 shows the fractional...

The water saturation distributions for the previous cases can further explain what would happen at different mobility ratios. The water saturation profile for Case viscOl at 0.5 PV injection is shown in Figure 4.6. Because the mobility ratio between the displacing fluid and displaced fluid is 1, the displacing front is stable. The finger is not further developed, and the displacing front is sharp.
