    • Wateralternating gas (WAG) injection for enhanced oil recovery
      Water alternating gas (WAG) injection process was proposed in the 1950s to improve the sweep efficiency of gas flooding. Application of alternating water and gas cycles has led to the minimalization of unfavorable effects caused by high mobility of gas, and to the better macroscopic displacement efficiency of the injected fluids. This paper gives brief background on the theory of the WAG process, and an overview of its practical implementation in the world oil and gas industry. The need of the implementation of enhanced oil recovery methods on the national oil fields was also mentioned. ...more
