Experimental Stand and Methodology for Conducting Experiment to Measure the Solubility Coefficient of Supercritical Carbon Dioxide in Hydrocarbons in a Homogeneous Porous Medium

The article presents the results of studies of the process of oil displacement with supercritical CO2 fringes and water from a low-permeable heterogeneous oil reservoir with a water content of 8% at a pressure of 8 and 12 MPa. The results show that an increase in the CO2 injection pressure does not lead to an increase in the oil displacement coefficient within the experimental error. The mechanism of the process of displacing oil from a low-permeable heterogeneous reservoir is considered. The results of the experiment are processed in the form of a generalizing dependence.
