Short core displacements were conducted to evaluate miscible condensing-gas drive for the Sadlerochit reservoir of the Prudhoe Bay field. The cores were from well No. DS 14-5. The enriched gas was a 60 to 40 blend on a mole basis of rich Sadlerochit gas and the liquids from the Field Fuel Gas Unit and the separators at Flow Station 3. The experimental program consisted of 4 floods conducted in each of 4 cores for a total of 16 displacements. The floods consisted of gravity-stabilized continuous gas injection displacements with the core (1) at connate water saturation or (2) at waterflood residual oil saturation; and simultaneous injection brine enriched-gas floods at a 4 to 1 brine-to-gas ratio with the core (1) at connate water saturation or (2) at waterflood residual oil saturation.
