خلاصه مقاله:
Asphaltene depositions are serious problem encountered during the exploration of the oil reservoirs, miscible flooding, heavy oil recovery, or even primary depletion. A thermodynamic model was used to model asphaltene precipitation in crude oil in the reservoir. The asphaltene is assumed pure pseudo-component in solid phase. The characterization of unknown-heavy fraction of petroleum (i.e. C7+) was obtained with Whitson et al. method and assumed the heaviest component of crude oil is divided by two components, precipitating and non-precipitating. The results are good agreement with some experimental data.
