Asphaltene deposition in the reservoirs, tubbing, and surface facilities causes serious flow
assurance problems with significant economic implications. Asphaltene flow assurance …

Asphaltenes, the most aromatic of the heaviest components of crude oil, are critical to all
aspects of petroleum utilization, including reservoir characterization, production …

The Yen–Mullins model, also known as the modified Yen model, specifies the predominant
molecular and colloidal structure of asphaltenes in crude oils and laboratory solvents and …

Asphaltene adsorption at solid surfaces is a ubiquitous phenomenon that begins within the
production well and continues through the entire production chain. It is generally an …

Asphaltenes, the most aromatic of the heaviest components of crude oil, are critical to all
aspects of petroleum use, including production, transportation, refining, upgrading, and …

Modern production methods and environmental constraints demand chemical solutions. And
as oilfields age, the need for chemicals to ensure steady production increases. Production …

Previously, asphaltene science had been hindered by many significant uncertainties
regarding molecular weight, molecular structure, and nanocolloidal characteristics in …

In this work, we evaluate the effect of nanoparticles and nanofluids as viscosity reducers for
heavy crude oil (HO). The effect of alumina, silica and acidic silica nanoparticles was …

Analytical chemistry is powerful in analyzing complex mixtures of crude oil and brine
subsurfaces on the basis of atomic and molecular levels. Geochemistry applies chemical …

The aquathermolysis process is widely considered to be one of the most promising
approaches of in-situ upgrading of heavy oil. It is well known that introduction of metal ions …
