Asphaltene molecules as one of the most challenging components of crude oil play a key role in the interfacial behavior of the oil/water interface, especially during enhanced oil recovery processes. In this study, the behavior of archipelago asphaltene molecules is examined by molecular dynamics simulations in deionized water and brines with different salinities. The results verify the experimental observations that asphaltene molecules are adsorbed at the interface as a result of interactions with ions of water. In this simulation, by adding different ions of sea water to our brine, asphaltene molecules are more adsorbed at the interface.
