Salinity-dependent wettability alteration [PDF]
, 2020 Low salinity water flooding is a technique where, by injecting reduced salinity seawater, oil recovery can be significantly improved in some sandstone reservoirs. It has been generally agreed upon that this works predominantly by improving the water wettability of the reservoir rock.

Altering Emulsion Stability with Heterogeneous Surface Wettability [PDF]
Scientific Reports, 2016 AbstractEmulsions–liquid droplets dispersed in another immiscible liquid–are widely used in a broad spectrum of applications, including food, personal care, agrochemical and pharmaceutical products. Emulsions are also commonly present in natural crude oil, hampering the production and quality of petroleum fuels.
