A multiscale method for simulating fluid interfaces covered with large molecules such as asphaltenes [PDF]
J. Comput. Phys. (2016), vol 327, pp. 576-611, 2018 (Abbreviated) In this paper we report on the development of a multiscale method for simulating complex liquid-liquid systems such as water in contact with oil containing asphaltenes. We consider simulations where water drops covered with asphaltenes are deflated, and reproduce the crumpling observed in experiments.

Asphaltene precipitation trend and controlling its deposition mechanism
Natural 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.

Isolation of Asphaltene-Degrading Bacteria from Sludge Oil
Makara Journal of Science, 2015 Sludge oil contains 30%–50% hydrocarbon fractions that comprise saturated fractions, aromatics, resins, and asphaltene. Asphaltene fraction is the most persistent fraction.

Cooee bitumen II: Stability of linear asphaltene nanoaggregates [PDF]
J. Chem. Phys. 141, 144308 (2014), 2014 Asphaltene and smaller aromatic molecules tend to form linear nanoaggregates in bitumen.Over the years bitumen undergoes chemical aging and during this process, the size of the nanoaggregate increases. This increase is associated with an increase in viscosity and brittleness of the bitumen, eventually leading to road deterioration.

Asphaltene aggregation onset during high-salinity waterflooding of reservoirs (a molecular dynamic study) [PDF]
, 2019 The primary objective of this study is to establish an understanding of the role of high-salinity brine on the intensity of asphaltene aggregation onset during waterflooding of petroleum reservoirs. We already have shown that asphaltenes have a high tendency to form aggregates during waterflooding process when pure- and low salinity-water are injected ...

Size distribution of primary submicron particles and larger aggregates in solvent induced asphaltene precipitation [PDF]
arXiv, 2022 Asphaltene precipitation is a crucial phase separation phenomenon in the oil industry, especially in paraffinic froth treatment to extract bitumen from oil sands ores. This work reveals the formation of particles at 0.2 to 0.4 um in radius, defined as a primary sub-micron particle (PSMP), which is ubiquitous from diffusive mixing between asphaltene ...

COOEE bitumen. Chemical aging [PDF]
J.Chem. Phys. 139, 124506 (2013), 2013 We study chemical aging in "COOEE bitumen" using molecular dynamic simulations. This model bitumen is composed of four realistic molecule types: saturated hydrocarbon, resinous oil, resin, and asphaltene. The aging reaction is modelled by the chemical reaction: "2 resins $\rightarrow$ 1 asphaltene".
