摘要：
The invention provides an improved method for extracting heavy oil or bitumen contained in a reservoir. The invention involves directing the formation of a solvent fluid chamber through the combination of directed solvent fluid injection and production at combinations of horizontal and/or vertical injection wells so as to increase the recovery of heavy oil or bitumen contained in a reservoir. The wells are preferably provided with flow control devices to achieve uniform production.
