Foamy oil flow in heavy oil-solvent systems tested by pressure depletion in a sandpack

摘要

In this study, pressure depletion tests on foamy oil flow were conducted in a one-meter-long sandpack system to investigate the effect of pressure depletion rates on different heavy oil-solvent systems in porous media. Pure methane, pure propane, and a mixture of methane and propane were recombined respectively into a typical Manatokan dead heavy oil sample to generate live oil samples, four different pressure depletion rates were undertaken for each heavy oil-solvent system.
