Abstract

Il est décrit un procédé de récupération dhydrocarbures à partir dun réservoir de sables bitumineux ayant une zone de fluide mobile au-dessus dune zone de bitume. Le procédé consiste à générer, dans la zone de bitume et à travers un procédé pour améliorer la mobilité, une zone mobilisée en récupérant au moins une partie du pétrole initial en place; à injecter un gaz oxydant à travers un puits dinjection de gaz oxydant dans le réservoir pour supporter une combustion sur place dans le réservoir; à générer une communication fluidique entre la zone de fluide mobile et la zone mobilisée; et à récupérer des hydrocarbures mobilisées par la combustion sur place au moyen dun puits de production dhydrocarbures en communication fluidique avec la zone de fluide mobile et la zone mobilisée, la combustion sur place se propageant au moins dans la zone mobilisée.
