<p>A method for displacing hydrocarbons from a hydrocarbon-bearing subterranean reservoir by injecting a displacing fluid comprising a primary fluid such as carbon dioxide or rich gas, and an additive such as nitrogen, methane, flue gas, propane, butane, LPG, hydrogen sulfide, carbon monoxide, and mixtures thereof, said additive having a concentration sufficient to adjust the phase equilibrium of mixtures of the displacing fluid with reservoir hydrocarbons. The additive adjusts the phase equilibrium so that utilization of the displacing fluid is more efficient.</p> |
