Abstract

​

This article is devoted to the assessment of the applicability of water alternating gas (WAG) in the conditions of the objects of the Tyumen sweet. To assess the applicability of water-gas exposure, various experiences of using this technology on low-permeability objects are considered. Field experience shows that the efficiency of WAG use depends primarily on the reservoir permeability. Simulation of various methods of stimulation (waterflooding, gas injection, WAG) on objects with low permeability indicates that gas and water-gas methods are more effective than classical waterflooding. Field experience and simulation results are supported by core studies showing high efficiency of gas stimulation techniques. The author has developed an automated utility for determining the effectiveness of the implementation of various methods based on the geological and physical characteristics of the reservoir. The results of the utility's work confirm the high potential efficiency of gas and water-gas methods at the facilities of the Tyumen sweet.
