| 发明名称 | Recovery from a subsurface hydrocarbon reservoir | ||
| 摘要 | Methods and systems for improving recovery from a subsurface hydrocarbon reservoir are described. A method includes drilling a horizontal well in a zone proximate to a contiguous section of cap rock over a reservoir interval. A refrigerant is flowed through the horizontal well to freeze water in the zone, forming a freeze wall in contact with the contiguous section of cap rock. A chamber is formed above the reservoir interval, wherein the chamber includes the contiguous section of cap rock and at least one freeze wall. | ||

| 主权项 | 1. A method for improving recovery from a subsurface hydrocarbon reservoir, comprising: drilling a horizontal well in a zone proximate to a contiguous section of cap rock over a reservoir interval; flowing a refrigerant through the horizontal well to freeze water in the zone, forming a freeze wall in contact with the contiguous section of cap rock; forming a chamber above the reservoir interval, wherein the chamber comprises the contiguous section of cap rock and at least one freeze wall; and flowing a gas into the chamber to displace water from the chamber. | ||
