Abstract:
A method of Enhanced Oil Recovery from oil zones in a subterranean geological formation, and from oil zones. The method including: a first injecting step of injecting a first composition including CO2 into the subterranean geological formation for a period of time; a second injecting step of injecting a second composition including CO2 and a hydrocarbon into the subterranean geological formation for a period of time, wherein the first composition and the second composition are different; and extracting oil from the subterranean geological formation.
