Abstract

"PROCESS FOR CONFINING STEAM INJECTED INTO
A HEAVY OIL RESERVOIR"

ABSTRACT OF THE DISCLOSURE
The process is practised in the context of a first pattern of wells completed in a first portion of a heavy oil reservoir. The first pattern has undergone steaming and production and the underlying reservoir portion is significantly depleted. A second pattern of wells is completed in a second less-depleted portion of the reservoir. The two reservoir portions are adjacent and in fluid communication. This may be through a laterally extending thief zone high in the reservoir, the thief zone having higher permeability to steam than the main body of the reservoir. Steam injected into the second portion thus will be lost into the depleted portion. The process comprises injecting non-condensable gas into the depleted portion while steaming and producing oil from the less-depleted second portion. The gas is injected at a rate sufficient to maintain the pressure in the two reservoir portions about equal. As a result, the loss of steam to the depleted portion is inhibited.
