Enhanced Oil Recovery From Highly Heterogeneous Terrigenous Reservoirs by Mobilizing Bound Water in the Reservoir
Year: 2026
Type: article
Abstract: The article discusses the theoretical foundations and the results of laboratory and field tests of a chemical flooding technology based on the mobilization of bound water. The physical process of boundwater mobilization increases the displacement efficiency by involving previously trapped oil ganglia in the filtration process and also increases the displacement efficiency by enabling drainage of low- and ultra-low-permeability reservoir zones. Testing the technology at a pilot site of the Western Elemes field made it possible to select a geologically isolated area, thereby excluding the possible influence of well interference and/or other forms of impact on the reservoir. Evaluation of the test results unequivocally demonstrates the high efficiency of this technology for the specified reservoir type.
