This work concerns with simulation of permeability impairment as a result of asphaltene deposition at the field scale, which is a real situation of oil production from petroleum reservoirs.The involved processes are the initial precipitation of asphaltene from the reservoir fluid, the flocculation of these precipitates into larger particles and the deposition of these particles in porous media. The alteration of porosity and the impairment of permeability due to asphaltene deposition are also investigated.The case study reveals that the static surface deposition may occur in certain situations even without the fluid flowing. However, during flow, the dynamic surface deposition is predominant. The plugging deposition may occur under certain conditions, depending on properties of the fluid, porous media, asphaltene precipitates, injection rate and pressure conditions.In addition, the effect of fracture properties on asphaltene deposition at reservoir condition was investigated. The developed dual-porosity and dual permeability simulation model also has been used for some sensitivity analysis of parameters affecting asphaltene deposition in reservoir. The results of sensitivity analysis showed that dynamic and static 2 parameters of asphaltene play crucial role in the field performance and formation damage. Also, the results confirmed that, the permeability reduction due to asphaltene deposition in the fractures is more considerable than in the matrix media.

“…Considering the two phases of asphaltene and oil, different equations including mass balance, momentum balance, and equations related to asphaltene deposition kinetics (Wang et al, 1999;Wang and Civan, 2001) are employed for modeling the asphaltene deposition in porous media of petroleum reservoirs (Monteagudo et al, 2002;Leontaritis, 2005). The mass balance equation for oil component that is assumed only in the liquid phase is explained as follows:…”

A novel dynamic model for accurate evaluation of the effects of different process variables on the asphaltene precipitation process in petroleum reservoirs is presented. Different deposition mechanisms such as surface deposition, pore throat plugging, deposits entrainment, and asphaltene adsorption are properly incorporated in the proposed multiphase model. The variations of porosity, permeability, and pressure profiles are in good agreement with the available experimental data. The presented approach can have potential application for evaluation of the asphaltene precipitation process in petroleum reservoirs at different operating conditions.

“…The flocs can adsorb on the rock surface, can be trapped within the porous media because of their size (plugging) or can be entrained and returned to the oil phase because of high, local velocity (shear) [24]. Wang and Civan (2001) introduced the following equation for asphaltene deposition rate [25]: …”
