Publication number: 20110139432Abstract: Methods and apparatus for enhanced and improved viscous oil recovery are disclosed. A horizontal well is drilled through the viscous oil formation. A liner includes temperature actuated valves for delivering steam more uniformly along the heel and toe portions of the liner. The temperature actuated valves include an actuation mechanism that actuates from an open position to a closed position to control the flow of the steam therethrough. The actuation mechanism actuates to the closed position when it exceeds a predetermined temperature. 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.Type: ApplicationFiled: December 14, 2010Publication date: June 16, 2011Applicant: Chevron U.S.A.
