METHOD, SYSTEM AND PROGRAM STORAGE DEVICE FOR RESERVOIR SIMULATION UTILIZING HEAVY OIL SOLUTION GAS DRIVE

摘要

A method a system and a program storage device for predicting a property of a fluidfrom a subterranean reservoir containing heavy oil entrained with gas The methooincludes developing a baseline correlation between gas relative permeabilityk(rg) and gas saturation S(g), and capillary number N(c) calculated from a pluralityof cells and at least one of critical gas saturation S(gc) and gas relative permeabilityk(rgro) based upon plurality of depletion rates The baseline correlation isthen adjusted to comport with at least one of S(gc) and k(rgro) to produce a pluralityof corresponding adjusted baseline correlations where gas relative permeabilitiesk(rg) are selected A reservoir simulation is then run utilizing the selectedrelative permeabilities k(rg) to predict a property of at least one fluid
