Abstract
In a globalized world, the demand for energy is always growing. Since the oil and gas industry is responsible for delivering most of this demand, this makes hydrocarbon components increasingly important in the worldwide economy. However, such resources are finite, so a conscious exploration always seeking the maximum performance is required. As oil reservoirs after the application of primary and secondary recovery techniques usually still have about 65% of the original oil volume contained in their pores, methods that aim its reduction are gaining an increasingly important role in the energy industry. In this context, this work presents a three-dimensional micromodel representative of a porous medium that is used for pore-scale flow analysis. Confocal microscopy is used to visualize the microscale phenomena, leading to specific information about ganglia dynamics, related to its formation, mobilization and entrapment. The residual oil saturation, an important value to measure the amount of oil produced in a given reservoir is determined for different flow conditions. The results show that the suspensions composed by flexible microcapsules could be used as a mobility control agent, since it modifies the fluid distribution in the porous media, which results on the improvement of the pore scale displacement efficiency, and consequently reducing the residual oil saturation.
