Abstract

In this research a laboratory study of ASP flooding process followed by polymer solution (for mobility control) were performed in industrial core consist of marble, physical simulated the reservoir properties of productive Jreebi formation in DERO field. From my precedent studies: I found the types and optimum concentrations of ASP components that achieve maximum efficiency at minimum concentration (minimum interfacial tension for surfactant and alkaline - maximum viscosity for polymer). these types and optimum concentrations is  NaOH 0.7%wt, DDBSCa (Wetconat1220EH) 0.05%wt and Xanthan Gum 550 PPM. ASP flooding processes were performed by the following volumetric ratios: 15-30-50 %PV followed by 15% PV of polymer solution (for mobility control) . Finally displacement liquid were injected up to 250%PV. All ASP flooding processes were performed in the formation conditions of DERO field.
Results of the laboratory study referred to increasing of oil producing and decline of produced water at all ratios of ASP solution
