Abstract
Il est décrit des hydrocarbures lourds récupérés à partir dun réservoir souterrain à laide dun procédé de récupération hybride comprenant un procédé axé sur la vapeur deau et un procédé axé sur les solvants. Le procédé comprend une injection de vapeur dans le réservoir dans le but de jouer un rôle lors de la récupération dhydrocarbures à partir du réservoir par le procédé axé sur la vapeur d'eau jusquà ce quun seuil crête du procédé soit atteint. Une chambre de vapeur est conçue dans le réservoir par injection de vapeur d'eau, et une vapeur dominante dans la chambre de vapeur pendant le procédé dominant la vapeur d'eau est la vapeur d'eau. Une fois le seuil crête du procédé atteint, un solvant et de la vapeur d'eau sont co-injectés dans la chambre de vapeur pour faciliter la récupération ultérieure des hydrocarbures du réservoir par le procédé dominant le solvant, de sorte que la chambre de vapeur est encore détendue et la vapeur dominante dans la chambre de vapeur détendue est une vapeur du solvant injecté. Un fluide comprenant le solvant et les hydrocarbures est récupéré à partir du réservoir.
