Water alternating gas (WAG) injection is an improved oil recovery method that involves three-phase fluid flow, it was implemented to improve the sweep efficiency of gas, by injecting a slug of water to control the mobility ratio and to stabilize the gas displacement front. Then was demonstrated that WAG injection in the optimized proportions leads to improved oil recovery by combining better mobility as the injected gas mix with the residual oil, and contacting upswept oil, which leads to a better microscopic displacement compared to pure gas or pure water.
WAG flooding has been successfully applied to more than 60 oilfields worldwide. This course will present WAG Miscible, WAG Immiscible, WAG alternating with different Hydrocarbon Gases and Non-HC such as N2 and CO2 Gases.
The Factors Influencing a Wag Process such as fluid properties and rock-fluid, availability and composition of injection gas, heterogeneous permeability, injection pattern, capillary pressure, relative permeability, and rock wettability will be examined in a WAG process context. A field WAG actual case is presented and discussed in the course as well as Laboratory research cases and results.
