Experimental Study on CO2–Crude Oil Phase Behavior, Miscibility and Threshold Pressure Gradient for CCUS in Ultra-Low Permeability Reservoir

The Chang 8 reservoir in the Baima Middle Block of the Ordos Basin is an ultra-low-permeability reservoir that has faced formation-pressure depletion, a rising water cut, and poor remaining-oil recovery during long-term water-injection development. CO2 flooding in CCUS can simultaneously enhance oil recovery and achiev...
