Title (EN) Downhole Fluids Containing Cyclic Orthoesters and Brine and Methods for Using the Same
(FR) FLUIDES DE FOND DE TROU CONTENANT DES ORTHOESTERS CYCLIQUES ET DE LA SAUMURE ET PROCÉDÉS D'UTILISATION DE CES DERNIERS
Abstract:
(EN) Compositions and methods for treating a downhole environment are provided. The method includes introducing a treatment solution containing a cyclic orthoester and brine into a wellbore within the downhole environment and hydrolyzing the cyclic orthoester to produce an acid within the downhole environment.
(FR) La présente invention concerne des compositions et des procédés de traitement d'un environnement de fond de trou. Le procédé comprend l'introduction d'une solution de traitement contenant un orthoester cyclique et de la saumure dans un puits de forage à l'intérieur de l'environnement de fond de trou et l'hydrolyse de l'orthoester cyclique pour produire un acide dans l'environnement de fond de trou.
