Impact of Asphaltene Surface Energy on Stability of

Asphaltene is a complex macromolecule whose abundance strongly affects physical and interfacial properties of crude oil Asphaltene molecules may precipitate during crude oil production/transportation which may lead to plugging/clogging of wellbores, pipelines, and equipment In this study, the solubility of asphaltene in toluene has been investigated by calculation of non-covalent interaction.

Carbon Dioxide Storage in High Asphaltene Content Oil

Abstract Carbon dioxide storage in high viscosity and density hydrocarbon reservoirs that have high asphaltenes content is attractive However, CO 2 is an asphaltenes insoluble solvent, hence, CO 2 injection into these reservoirs is expected to cause asphaltenes deposition In pore-scale, how the deposition of asphaltenes would impact the CO 2 trapping and consequently CO 2 storage is not known.
