ABSTRACT:
A process for upgrading whole crude oil utilizing a recovery fluid, depressurizing an extracted whole crude oil/recovery fluid mixture in a step-wise fashion, and subsequently contacting at least a portion of the whole crude oil with supercritical water fluid to produce high value crude oil having low sulfur, low nitrogen, and low metallic impurities for use as hydrocarbon feedstock.
