The author of the article would like to thank Alexey D.Yapryntsev(Kurnakov Institute of General and Inorganic Chemistry of the Russian Academy of Sciences)for studying the samples by scanning electron microscopy.The author thanks the staff of the A.E.Arbuzov Institute of Organic and Physical Chemistry,“Kazan Scientific Center of Russian Academy of Sciences”,laboratory of Chemistry and Geochemistry of Petroleum and organizers of International Conference on Petroleum Phase Behavior&Fouling“PetroPhase2017”for providing samples of asphaltenes and resins.This work was performed within the framework of the state task(by Ministry of Science and Higher Education of the Russian Federation)of the Oil and Gas Research Institute of Russian Academy of Sciences(Project No.122022800364-6).
This paper presents the study of the effect of multiple ultrasonic impacts on submicron asphaltene aggregates in a toluene/heptane solution,conducted with dynamic light scattering technique.The objects of the study we...
The authors acknowledge the Nigerian Geological Survey Agency(NGSA)which made available core samples(from shallow exploration wells in the bitumen belt of Eastern Dahomey Basin)used for this study.Flash pyrolysis-gas chromatography(Py-GC)analyses were performed at the Geochemistry Laboratory of Newcastle University,United Kingdom.
The asphaltene fractions of the bitumens of Eastern Dahomey Basin in Nigeria,were analyzed by flash pyrolysis-gas chromatography(Py-GC)method in order to unravel its geochemical history and properties.The distribution...
