The investigation of pollutant behavior at water interfaces is critical to understand pollution in
aquatic systems. Computational methods allow us to overcome the limitations of …

The internal structure of heavy oil plays an important role in the research of the viscosity
reduction mechanism of heavy oil. On the one hand, the influence of heavy oil composition …

Shale gas/oil remaining in blind pores accounts for a large proportion in total reserves,
which is urgent to be further exploited. Understanding the microscopic mechanism of gas/oil …

We performed numerical investigations of the agglomeration behaviour of asphaltene
particles in a turbulent pipe flow by using a commercial discrete element modelling (DEM) …

In crude oil development, it is important to improve the dispersibility of asphaltene (ASP),
and to achieve viscosity reduction. Adding dispersants is a promising solution to postpone …

The aggregation and deposition of asphaltene pose significant challenges to efficient oil
production. However, the application of molecular dynamics (MD) simulations for …

Demulsifiers are crucial for enhancing crude oil extraction and transportation efficiency by
facilitating the separation of oil–water emulsions. However, research conducted on the …

Behaviors of asphaltene molecules in toluene under a shear force field were investigated by
dissipative particle dynamics (DPD). The results showed that asphaltene molecules …

Adding pour point depressant is an important method to solve the poor low temperature
rheology of waxy crude oil. Although the traditional polymer pour point depressant has good …

The phenomenon of asphaltene association and aggregation in petroleum has an important
impact on the exploitation, upgrading, storage and transportation of petroleum (especially …
