Title (EN) GEOCHEMICAL METHODS FOR MONITORING AND EVALUATING MICROBIAL ENHANCED RECOVERY OPERATIONS
(FR) PROCÉDÉS GÉOCHIMIQUES POUR SURVEILLER ET ÉVALUER DES OPÉRATIONS DE RÉCUPÉRATION À STIMULATION MICROBIENNE
Abstract:
(EN) Described herein are methods and techniques that utilize molecular geochemistry and isotopic signatures to monitor microbial enhanced gas and oil recovery operations. The methods and techniques utilize multiply substituted isotopologue signatures, clumped isotope signatures, and/or position-specific isotope signatures of one or more byproducts of the microbial stimulation techniques to determine the effectiveness of a microbial stimulation technique.
(FR) La présente invention concerne des procédés et des techniques qui utilisent la géochimie moléculaire et des signatures isotopiques pour surveiller des opérations de récupération de gaz et de pétrole à stimulation microbienne. Les procédés et les techniques utilisent des signatures d’isotopologue à substitution multiple, des signatures d’isotope agrégées et/ou des signatures d’isotope de position spécifique d’un ou plusieurs sous-produits des techniques de stimulation microbienne pour déterminer l’efficacité d’une technique de stimulation microbienne.
