Title
(EN) ULTRASONIC BREAKING OF POLYMER-CONTAINING FLUIDS FOR USE IN SUBTERRANEAN FORMATIONS
(FR) RUPTURE PAR ULTRASONS DE FLUIDES CONTENANT UN POLYMÈRE POUR UNE UTILISATION DANS DES FORMATIONS SOUTERRAINES
Abstract
(EN)
Methods for breaking polymer-containing treatment fluids for use in subterranean formations are provided, In one or more embodiments, the methods comprise providing a treatment fluid comprising a base fluid and a polymer, wherein the treatment fluid was used to treat at least a portion of a subterranean formation; and sonicating at least a portion of the treatment fluid to at least partially reduce the viscosity of the treatment fluid.
(FR)
Dans un ou plusieurs modes de réalisation, l'invention concerne des procédés de rupture de fluides de traitement contenant un polymère destinés à être utilisés dans des formations souterraines, les procédés comprenant la fourniture d'un fluide de traitement comprenant un fluide de base et un polymère, le fluide de traitement étant utilisé pour traiter au moins une partie d'une formation souterraine; et la sonication d'au moins une partie du fluide de traitement pour réduire au moins partiellement la viscosité du fluide de traitement.
