Abstract

Un procédé est décrit pour récupérer des hydrocarbures, comme des huiles lourdes, dun réservoir souterrain. Le procédé comprend lalimentation dun fluide aqueux sous-critique ou supercritique à température élevée et à haute pression dans le réservoir dhydrocarbures souterrain, linjection du fluide aqueux dans le réservoir pour chauffer les hydrocarbures dans le réservoir et récupérer ces hydrocarbures chauffés. Dans certains cas, le fluide supercritique est aussi utilisé pour valoriser les hydrocarbures et/ou faciliter le transport des hydrocarbures du site de production à un autre endroit, comme une raffinerie. Avantageusement, lexpansion isentropique peut être employée nimporte où dans le système afin de garantir des procédés et systèmes plus efficaces.
