It is generally believed that asphaltenes and resins as the polar components in crude oil can get adsorbed at the oil/water interface and act as a surface active agents. However, due to the complex behavior of asphaltenes and resins, the…
The current study investigates the synergistic/antagonistic effect of cationic (octyl pyridinium chloride [C8Py][Cl]), anionic (sodium lauryl sulfate (SLS)), and nonionic (octyl phenol ethoxylate (Triton-X100)) surfactants on the interfacial tension…
Brine-dependent recovery, which involves injected water ionic composition and strength, has seen much global research efforts in the past two decades because of its benefits over other oil recovery methods. Several studies, ranging from lab coreflood…
Injection of water with a designed chemistry has been proposed as a novel enhanced-oil-recovery (EOR) method, commonly referred to as low-salinity (LS) or smart waterflooding, among other labels. The multiple names encompass a family of EOR methods…
Recent studies have shown that although low salinity waterflooding leads to promising EOR impacts, it is to blame for the formation of unwanted water-in-oil emulsions. Thus, this study aims to explore the effect of water chemistry, namely ionic…
