Abstract

Remediation of the heavy organic deposits in the course of petroleum production has been a costly process and it has hampered the production activates in many parts of the world. Precipitation of ASPHALTENE in wells and reservoirs has detrimental effects on the economics of oil production as it reduces well production. On the other hand, using the knowledge of exact intermolecular intractions between molecules and the development of accurate nanoscale phase separations/transition models, it will be possible to increase our fundamental understanding of organic nanostructures. The basics of QUANTUM MECHANICS AND STATISTICAL THERMODYNAMICS are used to predict the potential energy and INTERMOLECULAR FORCES of ASPHALTENE molecules. The functional forms for potential energy and intermolecular force are evaluated. Calculated data are graphically compared with proposed models. A dimensionless INTERMOLECULAR POTENTIAL ENERGY function and forces are also proposed. A set of real data is used to check the validity of the calculated results. A well achieved agreement between one of the proposed models and the calculated data is promising.
