Asphaltene deposition is a ubiquitous problem in crude oil exploitation, which can cause the
blockage of pore throat, leading to a significant reduction of oil recovery. Understanding the …

Currently, the alteration of external factors during crude oil extraction easily disrupts the
thermodynamic equilibrium of asphaltene, resulting in the continuous flocculation and …

Polymer oil recovery technology has been widely applied, but the resultant increased
polymer-containing oil sludge are facing with treatment difficulties. Internal interactions of oil …

Carbonate reservoir rocks are normally mixed-wet or oil-wet, leading to low oil recovery
efficiency using water-based oil recovery methods. It is critical to understand the molecular …

Asphaltenes represent the most complex fraction of crude oil, consisting of a diverse range
of species with varying sizes, solubilities, aggregation states, structural motifs, and …

The structure of coal tar asphaltenes has been recognized as one of the most challenging
research topics in coal chemistry. In this work, a stepwise extraction subfraction separation …

The gas condensate reservoir is classified as a natural gas resource that produces
condensate liquid in the reservoir when the pressure in the reservoir drops below the dew …

Asphaltenes and waxes are two components of crude oil that cause flow assurance issues.
Although the components coexist, few studies have considered the effect of asphaltenes on …

Fouling phenomena are commonly observed in oil production processes, which have
caused many challenging issues. Many previous studies focused on fouling in aqueous …

Hydrothermal treatment (HT) can effectively dehydrate and reduce oily sludge (OS) volume,
but the resulting hydrothermal oily sludge (HOS) presents greater challenges for washing …
