Title (EN) METHODS OF MINIMIZING SULFATE SCALE IN OIL FIELD
(FR) PROCÉDÉS DESTINÉS À RÉDUIRE AU MINIMUM LE NIVEAU DE SULFATE DANS DES CHAMPS PÉTROLIFÈRES
Abstract: front page image
(EN)Methods of controlling barium sulfate scale in oil field applications are disclosed. These methods involve the application of one or more carboxylated oligomers to an aqueous system in the oil field. Carboxylated oligomers include polymaleic acid and polyethercarboxylates. Additionally, methods of neutralizing polymaleic acid and use of this neutralized product for barium sulfate scale control are disclosed.
(FR)L'invention concerne des procédés destinés à réguler le niveau de sulfate de baryum dans des champs pétrolifères. Ces procédés consistent en une application d'un ou plusieurs oligomères carboxylés dans un système aqueux d'un champ pétrolifère. Les oligomères carboxylés contiennent de l'acide polymaléique et des polyéthercarboxylates. Elle concerne, en outre, des procédés de neutralisation de l'acide polymaléique et l'utilisation de ce produit neutralisé dans la régulation du niveau de sulfate de baryum.
