Modeling cementation in porous media during waterflooding: Asphaltene deposition, formation dissolution and their cementation

In the development of the proposed model, the radial flow geometry has been adopted and a solution is sought to predict the deposition of asphaltene, rock dissolution and precipitation with respect to time and space. The developed model also predicts the phenomenon of cementation in the porous media and different factors that will enhance cementation. These factors include: asphaltene concentration, water injection rate, injection period, the depth and temperature of the reservoir. It is found from the detailed analysis that the cementation remain very low but it could cause complete pore plugging with time. The derived cementation model assumes that the temperature of reservoir remains constant during waterflooding and the interfacial tensional forces are negligible. But practically the latter may support the cementation process.
