Simulation of Convection Process during Miscible Gas Injection in Naturally Fractured Reservoirs

this study review main features of dual porosity and dual permeability models for simulation of fluid flow in naturally fractured reservoirs. We then focus on simulation of convection process during miscible gas injection into naturally fractured reservoirs which is one of the governing factors in prediction of ultimate recovery factor after miscible gas injection in to naturally fractured reservoirs. we will discuss governing equations on this type of process and will model our work with a numerical model for a test sample.
