Foam Assisted Water Alternating Gas (FA WAG) is one of Enhanced Oil Recovery method to increase oil production. It can only be implemented to reservoir already using water alternating gas (WAG) injection<1 • 311l.It can be placed in the reservoir by either co-injection of liquid and gas at fixed quality, or surfactantalternating- gas (SAG) injection. Studies confirmed that the use of foams for mobility control successful in reducing problems like early gas breakthrough and poor sweep efficiency. This study is important as the aim of all EOR's process is to increase the oil production. The purpose of this research is to analyse the effect of injection rates on oil production during FA WAG process. It will focus on process and mechanism involved during FA WAG process and also the SAG method. The results shows high injection rates of surfactant are stronger than the gas injection rates. However, injecting constantly high injection rates throughout the production life might affect reservoir pressure. The water productions will also increase as high surfactant slug injection rate is used. By doing this study, it proves that FA WAG process can be implemented commercially. The simulation works has been done to using ECLIPSE 100.
