Title
(EN) RECYCLING CO2 IN HEAVY OIL OR BITUMEN PRODUCTION
(FR) RECYCLAGE DE CO2 DANS LA PRODUCTION DE PÉTROLE LOURD OU DE BITUME
Abstract
(EN)
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.
(FR)
La présente invention concerne un procédé pour améliorer le rendement de production et la récupération de pétrole lourd ou de bitume et réduire la perte thermique à une charge supérieure et inférieure dans un procédé de production assisté par vapeur. Le procédé comprend l'injection stratégique de dioxyde de carbone recyclé dans le réservoir entre des puits de production. Les effets d'isolation thermique et de solvant fournis par du dioxyde de carbone dissout dans la phase huileuse facilitent l'amélioration souhaitée de récupération de pétrole, et renvoient simultanément le CO2 par séquestration dans le réservoir.
