文摘
PR-EOS is modified to calculate the black-oil properties by considering the capillarity effect in tight oil reservoirs. The effect of nano-pore size distribution on well performance is examined in detail. Sensitivity studies are performed to identify critical parameters affecting well performance with the capillarity effect. Considering the capillarity effect on phase behavior leads to an improvement in well performance in tight oil reservoirs.
