Title
(EN) METHOD OF ENHANCED OIL RECOVERY FROM GEOLOGICAL RESERVOIRS
(FR) PROCÉDÉ DE RÉCUPÉRATION DE PÉTROLE AMÉLIORÉE À PARTIR DE RÉSERVOIRS GÉOLOGIQUES
Abstract
(EN)
A method of enhanced oil recovery of remaining reservoir oil (1) from a subterranean geological reservoir (2), which has been subjected to at least one of a primary oil recovery and a secondary oil recovery, said enhanced oil recovery method comprises the steps of oil flooding the geological reservoir (2) using flooding oil (3), and recovering the reservoir oil (1) from the geological reservoir (2). Preferably, the flooding oil (3) comprises heavy crude oil being recovered from another geological reservoir. Furthermore, the invention comprises using heavy crude oil (3) for oil flooding a subterranean geological reservoir (2) and enhanced oil recovery from the geological reservoir (2).
(FR)
L'invention porte sur un procédé de récupération de pétrole améliorée de pétrole restant dans un réservoir (1) à partir d'un réservoir géologique souterrain (2), qui a été soumis à au moins l'une d'une récupération de pétrole primaire et d'une récupération de pétrole secondaire, ledit procédé de récupération de pétrole améliorée comprenant les étapes d'inondation d'huile du réservoir géologique (2) à l'aide d'huile d'inondation (3), et de récupération du pétrole de réservoir (1) à partir du réservoir géologique (2). De préférence, l'huile d'inondation (3) comprend du pétrole brut lourd récupéré à partir d'un autre réservoir géologique. De plus, l'invention comprend l'utilisation de pétrole brut lourd (3) pour l'inondation d'huile d'un réservoir géologique souterrain (2) et une récupération de pétrole améliorée à partir du réservoir géologique (2).
