USE OF STEAM-ASSISTED GRAVITY DRAINAGE WITH OXYGEN ("SAGDOX") IN THE RECOVERY OF BITUMEN IN LEAN ZONES ("LZ-SAGDOX") |
| 摘要 |
A process to recover hydrocarbons from a reservoir having at least one lean zone, wherein said lean zone has an initial bitumen saturation level less than about 0.6, said process including:
i) Initially injecting of oxygen into said reservoir;ii) Allowing for combustion of said oxygen to vaporize connate water in said at least one lean zone; andiii) Recovering said hydrocarbons from said reservoir. |
