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

Iraqi Journal of Chemical and Petroleum Engineering, 2023 Many oil and gas processes, including oil recovery, oil transportation, and petroleum processing, are negatively impacted by the precipitation and deposition of asphaltene. Screening methods for determining the stability of asphaltenes in crude oil have

Asphaltene Precipitation Modeling of Sadi Formation in Halfaya Iraqi Oil Field
Journal 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.

Probing Mechanical Properties of Water-Crude Oil Interfaces and Colloidal Interactions of Petroleum Emulsions using Atomic Force Microscopy [PDF]
, 2017 Atomic force microscopy (AFM) is frequently used to elucidate complex interactions in emulsion systems. However, comparing results obtained with “model” planar surfaces to curved emulsion interfaces often proves unreliable, because droplet curvature can ...

Medium dependence of asphaltene agglomeration inhibitor efficiency
, 2007 Applying chemical additives (molecule inhibitors or dispersants) is one of the common ways to control asphaltene agglomeration and precipitation. However, it is not clear why at some conditions the synthetic flocculation inhibitors as well as resins not ...

Fractionation of Asphaltenes in Understanding Their Role in Petroleum Emulsion Stability and Fouling [PDF]
, 2017 SARA fractionation separates crude oil into fractions of saturates (S), aromatics (A), resins (R), and asphaltenes (A) based on the differences in their polarizability and polarity.
