Prediction of the Gas Injection Effect on the Asphaltene Phase Envelope
Oil & Gas Science and Technology, 2015 Asphaltene instability may occur when pressure, temperature and compositional variations affect the reservoir oil. Permeability reduction, wettability alteration, and plugging of wells and flow lines are the consequences of this phenomenon. Therefore, it

Phase behavior in petroleum fluids (A Detailed Descriptive and Illustrative Account) [PDF]
arXiv, 2017 This chapter presents a descriptive and illustrative account of phase behavior in the seven naturally occurring petroleum fluids and ties all the known eleven phase-transition concepts in a unified narrative. The figures and tables contained in this report are designed so that they could effectively support the discussion about molecular make-up of ...

Research Progress in Nanoparticle Inhibitors for Crude Oil Asphaltene Deposition
MoleculesCurrently, the alteration of external factors during crude oil extraction easily disrupts the thermodynamic equilibrium of asphaltene, resulting in the continuous flocculation and deposition of asphaltene molecules in crude oil.

Investigation of Asphaltene Stability in the Iranian Crude Oils [PDF]
Iranian Journal of Chemical Engineering, 2008 The influence of different factors on the asphaltene stability in three iranian crude oils was evaluated. Compositional studies and structural characterization of resins and asphaltenes were carried out in order to study a possible relationship between ...

Iraqi Journal of Chemical and Petroleum EngineeringThe solubility of asphaltenes in crude oils is predominantly influenced by variations in temperature, pressure, and oil composition. These alterations can precipitate asphaltene deposition, resulting in diminished permeability, obstruction of wells ...

Curated dataset of asphaltene structures
Data in BriefAsphaltenes, a distinct class of molecules found in crude oil, exhibit insolubility in nonpolar solvents like n-heptane but are soluble in aromatic solvents such as toluene and benzene. Understanding asphaltenes is crucial in the petroleum industry due to their detrimental effects on oil processing, resulting in significant economic losses and ...
