Abstract
A particularly effective well configuration that can be used for single well steam assisted gravity drainage (SW-SAGD) wherein steam flashing through production slots is prevented by including passive inflow control devices (ICDs) or active interval control valves in the completion. A thermal packer separates the injection and production segments of a horizontal well having a toe and a heel, and the ICDs can be evenly spaced or can decrease towards the heel. The cumulative steam to oil ratio (CSOR) of the SW-SAGD well is thus lowered, as compared to the same well without passive flow control devices or active interval control valves.
