Organic precipitations are highly sticky and hard if some asphaltenes are present. This
causes a deposition problem to occur when thermodynamic conditions are suitable for …

Asphaltene precipitation and deposition has been recognized to be a significant problem in
oil production, transmission, and processing facilities. The precipitation of asphaltenes is …

Asphaltene precipitation and deposition in the reservoir, near-wellbore region, and pipelines
is one of the critical problems in flow assurance. It can cause a blockage of pore throats and …

Asphaltene is a solid oil component with a wide range of molecular compositions and
structures, making it one of oil's most complicated components. The deposition and …

Deposition of asphaltenes on the inner surface of oil wells and pipelines causes flow
blockage or significant production loss in these conduits. Generally, asphaltenes are stable …

In the last few years, large efforts have been made to develop advanced and smart
technologies that can predict and prevent asphaltene precipitation. In the history of …

Asphaltene is the heaviest and most polar fraction of crude oils, which is usually defined as
a solubility class, soluble in light aromatics, benzene and toluene, and insoluble in paraffins …

Although asphaltenes are always present in crude oils, they create problems only when they
become insoluble in the remainder of the oil. A change in asphaltene solubility can occur …

Sudden changes in key parameters such as pressure, temperature, and fluid composition
may result in asphaltene precipitation and deposition, consequently reducing permeability …

Asphaltene precipitation and deposition is a serious problem in many Iranian fields. The
deposited asphaltene results in partial or total blockage of the wellbore, reducing or …
