Numerical Simulation Study on Waterflooding Heavy Oil Based on Variable Threshold Pressure Gradient
The heavy-oil flow in porous media is characterized by non-Darcy law with variable threshold pressure gradient (TPG) due to the large fluid viscosity. However, available analytical and numerical models hardly consider this effect, which can lead to erroneous results. This paper is aimed at presentin...
