20110278001 | THERMAL MOBILIZATION OF HEAVY HYDROCARBON DEPOSITS - A method is provided for applying a thermal process to a lower zone underlying an overlying hydrocarbon zone with thermal energy from the thermal process mobilizing oil in the overlying zone. The lower zone itself could be a hydrocarbon zone undergoing thermal EOR. Further, one can economically apply a thermal EOR process to an oil formation of low mobility and having an underlying zone such as a basal water zone. Introduction gas and steam, the gas having a higher density than the steam, into the underlying zone displaces the basal water and creates an insulating layer of gas between the steam and the basal water maximizing heat transfer upwardly and mobilizing viscous oil greatly reducing the heat loss to the basal water, economically enhancing production from thin oil bearing zones with underlying basal water which are not otherwise economic by other known EOR processes. | 11-17-2011 |
20130118737 | METHOD FOR INITIATING CIRCULATION FOR STEAM ASSISTED GRAVITY DRAINAGE - A method for initiating steam assisted gravity drainage (SAGD) mobilization and recovery of hydrocarbons in a hydrocarbon-bearing formation includes initially forming a circulation path by connecting SAGD injection well and a circulation well. The circulation well can be a SAGD production well or a separate well completed adjacent a toe of the injection well. Initially, a thermal carrier such as steam or flue gases, is circulated, forming a thermal chamber about the injection well. One initial start-up is complete, the circulation path is decoupled for further propagating the thermal chamber and establishing steady-state SAGD operations. | 05-16-2013 |
