Title
(EN) METHOD FOR THE USE OF NITRATES AND NITRATE REDUCING BACTERIA FOR MITIGATING BIOGENIC SULFIDE PRODUCTION
(FR) PROCÉDÉ D'UTILISATION DES NITRATES ET DES BACTÉRIES RÉDUISANT LES NITRATES POUR DIMINUER LA PRODUCTION DE SULFURES BIOGÈNES
Abstract
(EN)
A method of controlling sulfides in a fluid including determining selected conditions of the fluid and selecting a nitrogen reducing bacteria (NRB) based on those conditions. The method further includes injecting an NRB into the fluid and injecting an inorganic nitrate into the fluid.
(FR)
Cette invention concerne un procédé de contrôle des sulfures dans un fluide comprenant la détermination de conditions choisies pour le fluide et le choix d'une bactérie réduisant l'azote (NRB) en fonction de ces conditions. Le procédé comprend en outre l'injection d'une NRB dans le fluide et l'injection d'un nitrate inorganique dans le fluide.
