Asphaltene precipitation and deposition are considered major problems in primary,
secondary and tertiary phases of oil production. These phenomena can cause partial or …

Asphaltenes are complex molecular entities, which together with resins, aromatic
hydrocarbons and saturates forms the crude oil. Asphaltenes and resins are in the …

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 …

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 …

As crude oil gets denser and heavier, the precipitation and deposition of asphaltene causes
severe problems in various sectors of oil industry from oil reservoirs to refineries. Asphaltene …

Asphaltene precipitation in reservoirs during production and Enhanced Oil Recovery (EOR)
can cause serious problems that lead to reduction of reservoir fluid production. In order to …

In this work, a new single-well model to simulate asphaltene precipitation, deposition, and
plugging of oil wells during primary production is developed. A four-component (asphaltene …

The potential problem of asphaltene deposition during oil production has motivated both
academics and industries to predict the asphaltene deposit profile in wellbores and …

Nowadays, the significance of hydrocarbon reservoirs as the main supply of world energy is
being increased more than before. Hence, a safe and continuous production process of oil …

Asphaltene deposition occurs in production lines and leads to a reduction in the production
rate due to the contraction of the area. Besides, remedies to treat the deposition costs the …
