Investigation of water-alternating-gas injection

Authors: N.A. Drozdov (Gubkin Russian State University of Oil and Gas)
The series of filtration experiments were carried out on sand packed reservoir models to study the influence of gas content in the water-gas mixture of oil displacement factor for the conditions of Russkoye and Samodurovskoye fields. Studies have shown the feasibility of water-gas mixtures injection into the reservoir, not only in terms of utilization of associated gas, but also in terms of enhanced oil recovery. The studies showed that water-alternating-gas (WAG) injection can become a very effective way to develop heavy oil fields.
