Improved crude oil base soluble oils are prepared from crude oils exhibiting gravities between about 27 DEG and 50 DEG API and pour points below about 55 DEG F. These soluble oil compositions contain about 45 to 90 volume percent of the selected crude oil, 4 to 30 volume percent surface active agents, 0.5 to 8 volume percent of a partially oxygenated liquid organic stabilizing agent, and up to about 60 volume percent water. Both the substantially anhydrous soluble oil containing only incidental water and the high water content microemulsions formed by the addition of from about 10 to 60 volume percent water to the soluble oil can be employed as miscible flooding agents for oil recovery and as water injection and producing oil well treating agents.
