Abstract
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.
