Abstract

Une méthode est présentée relativement à la récupération efficace énergétique et écologique in situ de bitume ou de pétrole lourd par injection de diméthyl éther (DME) dans le réservoir. La méthode comprend les étapes de chauffage du réservoir en employant la chaleur de condensation et la chaleur latente des vapeurs ou des liquides DME injectés, la mobilisation du bitume et du pétrole lourd en abaissant sa viscosité, la dissolution de leau et de certaines des composantes du bitume et du pétrole lourd dans le DME, la récupération du réservoir du mélange de bitume et de DME renfermant les composantes dissoutes de bitume, la séparation du DME du mélange par dépressurisation suivie de la mise sous pression, le chauffage et la réinjection du DME récupéré dans le réservoir.
