<p>A method relates to improving production rate and recovery of heavy oil or bitumen and reducing heat loss to over and under burden in a steam-assisted production process. The method includes strategically injecting recycled carbon dioxide into the reservoir between production wells. The heat insulation and solvent effects provided by carbon dioxide dissolved in the oil phase facilitate the desired improvement on oil recovery, and simultaneously sequester the CO2 back into the reservoir.</p>
