Title (EN) BIOLOGICAL AUGMENTATION OF LOW SALINITY WATER FLOODING TO IMPROVE OIL RELEASE USING NUTRIENT SUPPLEMENTATION
(FR) AUGMENTATION BIOLOGIQUE D'INJECTION D'EAU À FAIBLE SALINITÉ EN VUE D'AMÉLIORER UNE LIBÉRATION DE PÉTROLE À L'AIDE D'UNE SUPPLÉMENTATION EN NUTRIMENTS
Abstract:
(EN) A method of enhancing oil recovery includes the step of determining a specific nutrient package used to initiate a microbiological response under actual reservoir conditions in combination with low salinity water injection. Once determined, the specific nutrient package is applied to at least one targeted well to stimulate resident microorganisms such that size or hydrophobic properties are beneficially altered so that interaction with oil contained in a reservoir rock formation is improved.
(FR) La présente invention concerne un procédé d'amélioration de l'extraction de pétrole, lequel procédé comprend l'étape consistant à déterminer un ensemble de nutriments spécifiques utilisé en vue de lancer une réponse microbiologique dans des conditions réelles de couche pétrolifère en association avec une injection d'eau à faible salinité. Une fois déterminé, l'ensemble de nutriments spécifiques est appliqué à au moins un puits ciblé en vue de stimuler les microorganismes résidents de sorte que la taille ou les propriétés hydrophobes soient avantageusement modifiées de manière à améliorer une interaction avec le pétrole contenu dans une formation rocheuse de couche pétrolifère.
