Crude oils are complex mixtures of organic molecules, of which asphaltenes are the
heaviest component. Asphaltene precipitation and deposition have been recognized to be a …

In recent years, controlling the salinity and composition of the injected water has become an
emerging enhanced oil recovery (EOR) technique, often described as low salinity (LS) …

In a society where the global search for renewable and sustainable sources of energy,
chemicals and materials has rapidly become a priority, due to the challenges posed by …

Hypothesis. A large number of papers discuss merits and mechanisms of low salinity
waterflooding. For each mechanism proposed, there are counter examples to invalidate the …

Injection of modified salinity brines (MSB), ie brine with seawater-like salinity (SWS) and low
salinity water (LSW) in oil-wet carbonate rocks has proven to be relevant to improved oil …

Several laboratory experiments demonstrated that different water compositions cause rocks
to change from oil-to water-wet state. Although it is a consensus that wettability alteration is …

Low salinity effects (LSE) improved recovery could be obtained by reducing salinity and/or
modifying the specific ions of injected brines. Low salinity waterflooding (LSW) is described …

Low salinity waterflooding has become increasingly popular to improve recovery efficiency
in matured oil fields. Numerous underlying mechanisms behind the low salinity …

Spontaneous emulsification near the oil–water interface and destabilization of water-in-oil
emulsions in the bulk oil phase may affect the efficiency of improved oil recovery. In this …

The surface of silica nanoparticles (NPs) was modified by chemical grafting of ligands to:(1)
achieve colloidal stability in concentrated brine at salinities up to 25.7% total dissolved …
