Abstract
Linvention propose un procédé de récupération de pétrole dun réservoir. Le procédé comprend lintroduction de CO2 à travers un puits de forage dans le réservoir, le puits de forage ayant une pression de fond de trou supérieure à une pression de fracture du réservoir pour produire des fractures à lintérieur du réservoir et supérieure à une pression de miscibilité minimale entre le CO2 et le pétrole pour produire une zone miscible; larrêt de lintroduction de CO2 à travers le puits de forage pour une première période pour réduire la pression de fond de trou pour quelle soit inférieure à la pression de fracture et supérieure à la pression de miscibilité minimale; la réintroduction du CO2 pour maintenir la pression de fond de trou inférieure à la pression de fracture et supérieure à la pression de miscibilité minimale pour maintenir la zone miscible; la fermeture du puits de forage pour promouvoir le déplacement du CO2 à travers le réservoir dans une direction séloignant du puits de forage; et la récupération du pétrole du réservoir.
