Abstract:
A method of oil production is provided. The method includes forming an injection well and a production well. The method also includes pumping a mixture of oxygen and carbon dioxide (CO2) into the injection well. In addition, the method also includes minimizing gravity segregation by providing a relatively high level of CO2 in the mixture.
