Title (EN) MICROBUBBLES FOR TREATMENT CHEMICAL DELIVERY IN SUBTERRANEAN FORMATIONS
(FR) MICROBULLES POUR DISTRIBUTION DE PRODUITS CHIMIQUES DE TRAITEMENT DANS DES FORMATIONS SOUTERRAINES
Abstract:
(EN) Compositions, systems, and methods for delivering treatment chemicals, for example, to enhance conductivity in microfractures and/or low-permeability formations, are provided. In one embodiment, the methods comprise: providing a treatment fluid that comprises a base fluid and a plurality of microbubbles, wherein one or more of the microbubbles each comprise at least an outer shell and a treatment chemical within the shell, and have a diameter of about 100 microns or less; and introducing the treatment fluid into at least a portion of a subterranean formation. In some embodiments, the microbubbles may enter one or more microfractures in the subterranean formation and release the treatment chemical therein.
(FR) Cette invention concerne des compositions, des systèmes et des procédés permettant de distribuer des produits chimiques de traitement, par exemple, pour améliorer la conductivité dans des micro-fractures et/ou des formations à perméabilité réduite. Selon un mode de réalisation, les procédés comprennent : la fourniture d'un fluide de traitement qui comprend un fluide de base et une pluralité de microbulles, une ou plusieurs des microbulles comprenant chacune au moins une coque extérieure et un produit chimique de traitement à l'intérieur de la coque, et présentant un diamètre d'environ 100 microns ou moins ; et l'introduction du fluide de traitement dans au moins une partie d'une formation souterraine. Selon certains modes de réalisation, les microbulles peuvent pénétrer dans une ou plusieurs micro-fracture(s) dans la formation souterraine et libérer le produit chimique de traitement à l'intérieur de celle(s)-ci.
