3.
Table 1 shows the relative permeability data measured on a sandstone core plug as a function of
water saturation. Determine the relative permeability data from Table 1. If the sandstone was
invaded by high-pressure water drive (coming from the portion above the transition zone),
evaluate the percentage of recovery.
