Abstract
A soluble oil composition comprised of a liquid hydrocarbon, a preferentially oil-soluble surface active organic sulfonate, a preferentially water-soluble surface active organic sulfonate, and a stabilizing agent. The stabilizing agent can be a monohydric aliphatic alcohol containing 3 to 5 carbon atoms, a polyhydric aliphatic alcohol containing 3 carbon atoms, an aliphatic ketone containing 4 to 6 carbon atoms, a glycol ether containing 4 to 12 carbon atoms, or a dialkylene glycol containing 6 carbon atoms. The composition has particular utility as a displacement fluid in a flooding process for the recovery of oil, and for various well treating applications. The soluble oil composition can be substantially anhydrous, or it can contain water present as a water-in-oil microemulsion.
