Abstract
Abstract
Water alternating gas (WAG) injection technology is methods which may improve oil recovery efficiency by combining the effects from two traditional techniques—water and gas flooding. Both microscopic oil displacement and sweep efficiency can be enhanced by WAG implementation (Surguchev et al. 1992). WAG injection consists of injecting water and gas from the same injection wells which contribute to the improvement of overall sweep efficiency by:
