Effect of Phase Behavior on CO2 Displacement Efficiency at Low Temperatures: Model Studies With an Equation of State

Open publisher page 44 citations

Abstract

Summary In this paper, we examine the use of an equation of state (EOS) to predict the phase behavior of CO2/crude-oil systems at low temperatures. An adequate match of the experimental pressure/composition diagrams of a dead oil and two recombined oils from the Wasson field at 90°F [32°C] is obtained. The incorporation of three-phase flash calculations in a compositional model is described. The model is used to simulate CO2 slim-tube displacements and yields results that are consistent with experimental observations.
