ABSTRACT:
An enhanced oil recovery process uses a heated organic vapor to reduce the viscosity of a crude oil, especially heavy crude oil. The recovery process is also enhanced because the organic vapor forms a liquid phase miscible with the crude oil, thereby further reducing the viscosity of the crude oil.
