... Abstract Use of a horizontal well for steam injection, or for fluid production in thermal recovery, is of practical interest in field operations. Experiments were carried out in a high pressure steam model equipped with an axially placed horizontal well. Steam was either injected...

... to approach each specific field situation on its own merits, and design a thermal process to suit the conditions. Selected thermal recovery projects, specifically steam injection, in Saskatchewan are reviewed to determine what worked and what did not. For example, CSS did not have a chance in the thin...

... pattern for a Cold Lake oil sand deposit of 12.8 m thickness underlaid by a 2.2 m bottom water zone. In addition to steam-CO 2 conrinuous injection. CO 2 soak prior to steam injection, hot water-CO 2 injection and CO 2 followed by steam injection (CO 2 -steam sequential injection) were evaluated...

... of this resource is to be realized. Saskatchewan's heavy oil enhanced recovery projects have centered around steam injection and in-situ combustion. While steam Injection has been very successful, it is not expected to be economically feasible for those reservoirs which contain approximately eighty percent...
