Title (EN) PROCESS FOR INCREASING THE PRODUCTION OF HYDROCARBONS FROM HYDROCARBON BEARING RESERVOIRS
(FR) PROCÉDÉ PERMETTANT D'AUGMENTER LA PRODUCTION D'HYDROCARBURES À PARTIR DE RÉSERVOIRS PÉTROLIFÈRES
Abstract:
(EN) Process of increasing the productivity of hydrocarbon bearing reservoirs Process for increasing the production of hydrocarbons from hydrocarbon bearing reservoirs comprising at least the step of introducing an aqueous fluid comprising at least one chelating agent into the formation, wherein the chelating agent is a mixture of at least two different compounds. Preferably, the process is an acidizing and/or fracturing process.
(FR) L'invention concerne un procédé d'augmentation de la productivité de réservoirs pétrolifères. Le procédé d'augmentation de la production d'hydrocarbures à partir de réservoirs pétrolifères comprend au moins l'étape consistant à introduire un fluide aqueux comprenant au moins un agent chélatant dans la formation, l'agent chélatant étant un mélange d'au moins deux composés différents. De préférence, le procédé est un procédé d'acidification et/ou de fracturation.
