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.

Simulation of the Asphaltene Deposition Rate in Oil Wells under Different Multiphase Flow Condition
Energies, 2023 As the wellbore pressure falls below the bubble point pressure, the light components in the oil phase are liberated, forming additional vapor, and the single-phase flow becomes a gas–liquid two-phase flow.

NUMERICAL MODELING OF ASPHALTENE DEPOSITION [PDF]
Computational Thermal Sciences, 2013 Asphaltene deposition on the walls of wellbore or pipeline during oil production and processing will cause dire consequences if left untreated. A better understanding of this phenomenon is required. This study presents a general modelling framework based either on the level-set approach or the concentration approach for modelling asphaltene deposition ...

Bitumen Emulsion-Mineral Surface Interactions: An NMR Study on the Interface Layer Composition. [PDF]
Magn Reson ChemWe describe a 1H NMR approach to study the interface layer formed by a specified bitumen emulsion in the presence of non‐magnetic as well as magnetic minerals. This approach is based on the consecutive flushing off “bulky” components of the bitumen emulsion and the following extraction of the surface layer material, which can then be analyzed by NMR ...

Asphaltene Precipitation in Algerian Oilfields: Experimental Investigation and Field Mitigation
Chemical Engineering Transactions, 2014 This study addresses two aspects for mitigating the asphaltene precipitation and deposition problem in Algerian oilfields: experimental study and field solution to the deposition problem. In the experimental study and in order to differentiate cases with
