A Novel Method with Dilute Surfactant Flooding by Considering the Effect of Time and Temperature on Crude Oil Aging, Experimental Study on Heavy Oil of Bangestan [PDF]
Journal of Chemical and Petroleum Engineering, 2017 Wettability alteration has been a sophisticated issue for scientists and reservoir engineers since early 20th century; thus, many investigations have been carried out to determine wettability and enhance it to ideal conditions, which leads to improvement

A Mechanistic Study of Wettability Alterations in Sandstone by Low Salinity Water Injection (LSWI) and CO2 Low Salinity Water-Alternating-Gas (WAG) Injection [PDF]
E3S Web of Conferences, 2023 Low salinity water injection (LSWI), an emerging Enhanced Oil Recovery (EOR) method, has proven to be effective in increasing oil recovery by wettability alteration. As low salinity water is injected into the reservoir, the pre-established equilibrium is

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.

Water films, asphaltenes, and wettability alteration [PDF]
SPE/DOE Improved Oil Recovery Symposium, 1998 We present a transport model for asphaltene diffusion from an oil/water interface through a water film followed by adsorption at a solid/water interface. Using a Langmuir adsorption isotherm, the effect of asphaltene aqueous solubility and adsorption constant K on equilibration time are established.

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.

Journal of Mechanical Engineering and Sciences, 2021 Previous studies reported that the presence of surfactant increases nanoparticles surface wettability by in-situ surface activation. On the other hand, the excess of surfactant concentration has an inverse effect on particle hydrophobicity by altering ...
