Due to the diversity of alkali categories and reservoir conditions, varied oil recovery driving mechanism alkaline flooding is subjected different types emulsion generation. In this study, a modified bottle test method that assesses major type formation for preliminary prediction performance in introduced. The considers necessary energy input required mixing immiscible bulk phases at low interf...

Low Salinity Water (LSW) and Alkaline-Surfactant-Polymer (ASP) flooding are emerging enhanced oil recovery methods that help recover from the reservoir after primary secondary processes. Experimental studies on LSW ASP have indicated potential in additional recovery. In this paper, numerical simulation was performed to study combined effects of flooding. A heterogenous initially saturated with ...

Some of the limitations a cost-effective alkaline surfactant flooding method include chemical precipitation and other formation damage issue which has greatly affected application especially in high salinity reservoirs. This study ascertains chelating attributes Ethylene-diamine-tetracetic Acid-(EDTA/NaOH), investigates ability EDTA/NaOH an anionic to improve oil recovery heavy sandstone format...

Abstract Combination flooding, which performs well on both sweep efficiency and displacement efficiency, is being extensively utilized in Daqing Oilfield. Surfactant-polymer (SP) flooding alkaline-surfactant-polymer (ASP) are two of the most used combination techniques. According to findings, alkaline lowers oil-water interfacial tension reduces other component’s adsorption. Nevertheless, also ...
