Correlation between Fracture Porosity and Relative Permeability Curves and Its Application in SAGD

Yi Hu



This presentation shows that the Lattice-Boltzmann method is applicable to calculating fracture relative permeability curves at different fracture porosity; irreducible water saturation, residual oil saturation, and residual liquid saturation bear a linear correlation to fracture porosity, respectively. In SAGD process simulation, it is necessary to use fracture relative permeability at corresponding fracture porosity; in the future, liquid-gas relative permeability curves will be calculated using the Lattice-Boltzmann method.
