Abstract

See full text

Methods and apparatus for enhanced and improved viscous oil recovery are disclosed. A horizontal well is drilled through the viscous oil formation. A specially designed steam stinger is used to inject steam substantially uniformly into the entire horizontal extent of the well borehole without direct steam impingement on the production liner in the viscous oil formation. Heat from the steam mobilizes and lowers the viscosity of the heavy crude wherein the crude is then produced to the surface via conventional lift arrangements.
