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.

Asphaltene Precipitation Models: A Review [PDF]
Journal of Dispersion Science and Technology, 2015 Asphaltenes are the heaviest and the most polar fractions of crude oil and are defined as a solubility class (typically soluble in toluene but insoluble in n-alkanes like n-heptane). Precipitation and deposition of asphaltenes during production, processing, and transportation of oil are major challenges faced by the oil industry. Over the last 30 years,

Experimental Investigation and Modelling of Asphaltene Precipitation during Gas Injection [PDF]
Journal of Chemical and Petroleum Engineering, 2020 Due to the limited crude oil resources, the role of enhanced oil recovery (EOR) techniques in the production of the oil that has not been extracted during the primary and secondary oil production techniques is crucial.

A Novel Technique for Determination of the Onset of Alkane Induced Asphaltene Precipitation Using Accurate Density Measurements [PDF]
Iranian Journal of Oil & Gas Science and Technology, 2016 Onset of asphaltene precipitation is the key parameter in dealing with asphaltene problems because it is the starting point of the asphaltene separation from the solution.
