Asphaltenes and paraffin are considered the molecules present in heavy crude oils that tend to form aggregates that cause high viscosity values. Understanding the molecular interactions occurring in such aggregation phenomena is essential to apply…
This article provides a method to design a viscosity reducing agent, which builds a crude oil model through molecular simulation and calculates the type of monomer suitable for the viscosity reduction of the crude oil. Viscosity reducing agent was…
This study focuses on evaluating the differences between describing the asphaltene fraction using a unique average molecular structure compared to a multistructural approach by examining its effects on aggregation behavior using molecular dynamics…
The performances of multilayer Hex-star phosphorene (HP) for the CO2 removal from natural gas were investigated by molecular simulation combined with real adsorbed solution theory (RAST). The influences of pressure (0.01–3.0 MPa), molar fraction of…

Polymeric surfactant can simultaneously thicken aquous phase and reduce water–oil interfacial tension (IFT), which makes it present a great application prospect in the oilfield taword enhanced oil recovery (EOR). There are two kinds of polymeric…
The interaction between asphaltenes and hydrolyzed polyacrylamide (HPAM) at the oil-water interface is the key factor leading to the stability of polymer-containing wastewater/oil sludge in the oilfield. In this study, the asphaltenes extracted from…
