Miscible flooding process using improved soluble oil compositions
Patent
·
OSTI ID:6149294
A soluble oil composition is described which consists of a liquid hydrocarbon, a preferably oil-soluble organic sulfonate, a preferably water-soluble organic sulfonate, and a stabilizing agent that is useful as a flooding agent for displacing oil from subterranean petroleum reservoirs. A method for recovering oil from such reservoirs is provided, wherein the composition is injected into the reservoir through an injection well and thereafter an aqueous flooding agent is injected to drive the soluble oil composition toward a spaced production well. The soluble oil can be injected as a substantially anhydrous liquid or as a water-in-oil microemulsion. (30 claims)
