Abstract
Enhanced oil recovery (EOR) seeks to improve the recovery of oil from existing mature oil fields. It targets the oil left behind after conventional recovery by natural reservoir drive and water injection. The injection of surfactant polymer chemicals can enhance oil recovery by reducing the interfacial tension, allowing more oil to be released from its host rock and improving the flood conformance.
In this study, the principles and parameters of chemical surfactant polymer EOR mechanisms, which mobilise, displace and transport residual oil (i.e. build an effective oil bank) after water injection were investigated. The current understanding of when, and under what conditions, an oil bank is formed and maintained is limited. This is relevant in core-flow experiments that need to be appropriately interpreted and scaled, from the centimetre to the field scale, in various steps. Various factors that influence the dynamics of building a stable oil bank were evaluated, using an extensive core-flow experimental study with the aid of computed tomography scanning....
