This study examined an enhanced foam-flooding system incorporating nanoparticles and polymers under geological conditions of a reservoir the Shu 16 block in Yushulin oilfield. The is mainly comprised anionic foaming agent (CQS-1) nonionic surfactant (FH-1). We screened 17 foams by evaluating their volumes foam half-lives using Waring-blender dynamic analysis methods, were selected after examini...

Abstract Chemically enhanced oil recovery methods can provide a solution to increase recovery. Of these, surfactant- polymer flooding is common. Efficient selection of polymers and surfactants essential for successful EOR project. Detailed lengthy task that involves number studies. Our goal create fast method based on which the most promising be selected.

Abstract The wettability preference of carbonate reservoirs is neutral-wet or oil-wet as the prevailing hydrocarbon reserves that affects approximately half total production hydrocarbons world. Therefore, due to surface rocks notable fraction oil held inside their pores in comparison with sandstones. Since shifting toward water-wet system great interest, numerous components were used for this p...

Several studies have shown the synergetic benefits of combining various chemical enhanced oil recovery (CEOR) methods with engineered waterflooding (EWF) in both sandstones and carbonate formations. This paper compares capillary desaturation tendency hybrid combinations water (EW) CEOR their conventional counterparts. coreflood experiments were conducted, including EW-surfactant flooding (EWSF)...
