UPGRADING HEAVY OIL BY VISBREAKING

摘要

Methods, systems and other embodiments associated with upgrading heavy oil by visbreaking are presented. A method (900) of upgrading heavy oil includes mixing (902) raw heavy oil with flue gases, CO2 and/or steam to produce a mixed heavy oil. This mixture is then heated (904) to produce heated heavy oil. High pressure pulses are created (906) in the heated heavy oil to crack the heated heavy oil to produce cracked oil with a lower viscosity than the heavy oil.
