Abstract
A method of improving production in a steam assisted gravity drainage operation, the method including positioning a tubular system within a borehole, the tubular system including a plurality of inflow control devices; injecting steam into a formation to assist in drainage of targeted resources from the formation; receiving fluids at an inlet of the inflow control devices; and regulating thermal conformance in the formation by choking liquids at the inflow control devices when the liquids have a subcool lower than a predetermined subcool at a selected drawdown pressure.
