Title (EN) MISCIBLE SOLVENT ASSISTED GRAVITY DRAINAGE
(FR) DRAINAGE PAR GRAVITÉ ASSISTÉ PAR UN SOLVANT MISCIBLE
Abstract:
(EN) A method for enhanced or improved oil recovery includes injecting a miscible injection fluid comprising an unfractionated hydrocarbon mixture through an injection well into a hydrocarbon bearing reservoir at a structurally higher position to initiate gravity-stable displacement and gas cap expansion processes. Residual hydrocarbons in the hydrocarbon bearing reservoir are mobilized and displaced by the miscible injection fluid to a structurally lower position within the hydrocarbon bearing reservoir adjacent a production well through which they are produced to the surface.
(FR) Un procédé de récupération assistée ou améliorée du pétrole comprend l'injection d'un fluide d'injection miscible comprenant un mélange d'hydrocarbures non fractionnés à travers un puits d'injection jusque dans un gisement contenant des hydrocarbures en un point structurellement supérieur pour initier un déplacement stable sous l'effet de la gravité et des processus d'expansion du chapeau de gaz. Les hydrocarbures résiduels présents dans le gisement contenant des hydrocarbures sont mobilisés et déplacés par le fluide d'injection miscible jusqu'à un point structurellement inférieur situé à l'intérieur du gisement contenant les hydrocarbures en position adjacente à un puits de production à travers lequel ils sont amenés jusqu'à la surface.
