摘要 |
A method for producing bitumen or heavy oil from a reservoir, the method comprising: defining at least one lateral section of the reservoir for placement of patterns of heater wells above a producer well; placing the producer well at a substantially centered location at or adjacent to the bottom of the reservoir within each of the lateral sections; placing a triangular pattern of heater wells above the producer well; placing a regular or non-regular pentagonal pattern of heater wells, or a portion thereof, at or above the triangular pattern of heater wells; heating the reservoir with the triangular and pentagonal patterns of heater wells to conductively heat the reservoir and reduce the viscosity of the bitumen or heavy oil; and producing bitumen or heavy oil with the producer well. |

1. A method for producing bitumen or heavy oil from a reservoir, the method comprising:
a) defining at least one lateral section of the reservoir for placement of patterns of heater wells above a producer well; b) placing the producer well at a substantially centered location at or adjacent to the bottom of the reservoir within each of the lateral sections; c) placing a triangular pattern of heater wells above the producer well; d) placing a regular or non-regular pentagonal pattern of heater wells, or a portion thereof, at or above the triangular pattern of heater wells; e) heating the reservoir with the triangular and pentagonal patterns of heater wells to conductively heat the reservoir and reduce the viscosity of the bitumen or heavy oil; and f) producing bitumen or heavy oil with the producer well. |
