Title (EN) METHODS FOR IMPROVING THE DISTRIBUTION OF A SEALANT COMPOSITION IN A WELLBORE AND TREATMENT FLUIDS PROVIDING THE SAME
(FR) PROCÉDÉS POUR AMÉLIORER LA DISTRIBUTION D'UNE COMPOSITION D'ÉTANCHÉITÉ DANS UN TROU DE FORAGE ET FLUIDES DE TRAITEMENT AYANT LE MÊME EFFET
Abstract:
(EN) Methods for forming a fluid seal in a subterranean formation may comprise: providing a treatment fluid comprising an aqueous carrier fluid, a sealant composition, and a crosslinked polysaccharide composition. The treatment fluid is introduced into a wellbore penetrating a subterranean formation and the crosslinked polysaccharide composition is formed into a viscosified gel in the wellbore. The viscosified gel substantially spans the diameter of the wellbore and holds the sealant composition in place. After forming the crosslinked polysaccharide composition into a viscosified gel in the wellbore, forming a fluid seal in the wellbore with the sealant composition.
(FR) Cette invention concerne des procédés permettant de former un joint d'étanchéité dans une formation souterraine, lesdits procédés pouvant comprendre : l'utilisation d'un fluide de traitement comprenant un fluide porteur aqueux, une composition d'étanchéité, et une composition de polysaccharide réticulé. Le fluide de traitement est introduit dans un trou de forage pénétrant dans une formation souterraine et la composition de polysaccharide réticulé est convertie en gel viscosifié dans le trou de forage. Le gel viscosifié couvre sensiblement le diamètre du trou de forage et maintient la composition d'étanchéité en place. Après conversion de la composition de polysaccharide réticulé en gel viscosifié dans le trou de forage, la composition d'étanchéité forme un joint d'étanchéité dans le trou de forage.
