Abstract
A thermal oil recovery process is disclosed for use in an oil reservoir containing a plurality of laterally separated generally vertical wells that have been used for cyclic steam stimulation and that have left in the reservoir at least one of a heated depletion zone and a channel. The process includes the steps of: drilling a well having a horizontal section and an opening therein that is located laterally between at least two of the vertical wells and at a depth within the lower part of the reservoir; injecting a heated fluid through the two vertical wells to establish thermal communication with said horizontal well; and using steam drive and gravity drainage to recover oil from the reservoir through the horizontal well.
