Asphaltene precipitation is one of the most common problems faced by the oil industry throughout the world during oil production, transportation and refinery processes. In oil recovery, especially in gas injection, formation of asphaltene aggregation, following their deposition can result in plugging of the formation, well bore and production facilities and makes the process costly and sometimes uneconomical. Unfortunately, there is no predictive model for asphaltene problem treatment because the mechanisms of asphaltene precipitation and deposition are still under investigation due...

The architecture and geometry of the void space of a porous medium and its complementary grain matrix determine several macroscopic properties of the rock such as porosity, relative permeability and capillary pressure. Therefore, it is important to study the microscopic structure of the reservoir pores and understand the physical fluid displacements through them. One approach to this problem is pore-scale modeling that requires a detailed understanding of the physical processes occurring on the pore scale and a complete description of the morphology of the pore space. The pore scale network...
