Computer Simulation of Asphaltenes

open access: yesPetroleum Chemistry, 2018
The review describes theoretical approaches based on computer simulations at various levels of details (from quantum chemical calculations to atomistic and coarse-grained models) to study asphaltenes and systems containing asphaltenes. The used methods are described, their advantages and disadvantages are discussed in terms of computational costs and ...

Assessing the Interfacial Activity of Insoluble Asphaltene Layers: Interfacial Rheology versus Interfacial Tension.

open access: yesLangmuir, 2020
Asphaltenes have been suggested to play an important role in the remarkable stability of some water-in-crude oil emulsions, although the precise mechanisms by which they act are not yet fully understood.

A Novel Method for Mitigation of Asphaltene Deposition in the Wellstring [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2010
Asphaltene precipitation and deposition is a serious problem in many Iranian fields. The deposited asphaltene results in partial or total blockage of the wellbore and wellstring reducing or completely seizing oil production.

Asphaltene precipitation trend and controlling its deposition mechanism

open access: yesNatural Gas Industry B, 2022
The B oilfield is a large integrated oilfield in the Middle East. Asphaltene precipitates from crude oil and deposits on solid surfaces, affording considerable blockages of the formation, wellbore, and production equipment.

Asphaltene Precipitation Modeling of Sadi Formation in Halfaya Iraqi Oil Field

open access: yesJournal of Engineering, 2019
Asphaltene is a component class that may precipitate from petroleum as a highly viscous and sticky material that is likely to cause deposition problems in a reservoir, in production well, transportation, and in process plants.
