Modeling and optimization of alkaline-surfactant-polymer flooding and hybrid enhanced oil recovery processes

We investigated the potential of hybrid low salinity ASP flooding in which Low Salinity Waterflooding (LSW) was implemented in secondary production and followed by ASP flooding. This approach can provide a superior performance compared to the conventional chemical flooding because it provides better oil recovery in the secondary stage and promotes the synergy between a low salinity environment and ASP slugs. Finally, the proposed robust optimization workflow helps to increase a project NPV and significantly reduces the uncertainty range associated with geology.
