Title
(EN) USE OF PERCITRIC ACID IN OIL- AND GAS-FIELD OPERATIONS
(FR) UTILISATION D'ACIDE PERCITRIQUE DANS DES OPÉRATIONS EN CHAMP PÉTROLIFÈRE ET GAZIER
Abstract
(EN) The present disclosure generally relates to compositions containing percitric acid, treatment fluids containing such compositions and methods of using the treatment fluids during various oil-and gas-field operations including hydraulic fracturing, remediation, production, disposal well chemistry and cleaning equipment both above surface and downhole used in connection with oil- and gas-field operations.
(FR) La présente invention concerne d'une manière générale des compositions contenant de l'acide percitrique, des fluides de traitement contenant de telles compositions et des procédés d'utilisation des fluides de traitement pendant diverses opérations en champ pétrolifère et gazier, comprenant une fracturation hydraulique, une remédiation, une production, une chimie de puits de rejet et un appareillage de nettoyage pour une utilisation aussi bien au-dessus de la surface qu'en fond de trou en liaison avec des opérations en champ pétrolifère et gazier.
