Abstract
(EN) In accordance with one or more embodiments of the present disclosure, a low-density treatment fluid includes a base water-control system and at least one light-weight filler material. The base water-control system may include an inorganic material system comprising an aqueous colloidal silica and a water-soluble chemical activator for gelling the colloidal silica, or the base water-control system may include an organic material system comprising of polymeric material. The low-density treatment fluid may have a density of from 0.1 g/cm3 to 0.75 g/cm3. Also described are methods of recovering a target fluid from a subterranean cavity using such a low-density treatment fluid.
(FR) Selon un ou plusieurs modes de réalisation de la présente divulgation, un fluide de traitement basse densité comprend un système de régulation de l’eau de base et au moins un matériau de charge léger. Le système de régulation de l’eau de base peut comprendre un système de matières inorganiques comprenant une silice colloïdale aqueuse et un activateur chimique soluble dans l’eau pour gélifier la silice colloïdale, ou le système de régulation de l’eau de base peut comprendre un système de matières organiques comprenant un matériau polymère. Le fluide de traitement basse densité peut avoir une masse volumique de 0,1 g/cm3 à 0,75 g/cm3. L’invention décrit également des procédés de récupération d’un fluide cible à partir d’une cavité souterraine à l’aide d’un tel fluide de traitement basse densité.
