Abstract: System and method for conducting enhanced oil recovery by establishing a plurality of stacked, alternating slugs of gas and liquid travelling downhole into a subterranean well. The system can include a buffer tank including a liquid inlet through which liquid is received from a liquids source into the buffer tank, a gas inlet through which gas is received from a pressured gas source into the buffer tank, a gas outlet in fluid communication with gas reservoired in the buffer tank, and a liquid outlet in fluid communication with liquid reservoired in the buffer tank. The system can further include a pressure control configured to maintain a specified pressure in gas reservoired within the buffer tank and a fluid dispensing system in fluid communication with the gas and liquid outlets of the buffer tank.
