Title (EN) PERMEABILITY BLOCKING WITH STIMULI-RESPONSIVE MICROCOMPOSITES
(FR) BLOCAGE DE LA PERMÉABILITÉ AU MOYEN DE MICROCOMPOSITES SENSIBLES À DES STIMULI
Abstract: front page image
(EN)Disclosed is a two-component fluid loss control system comprising a core substrate and a polymeric shell cooperating with each other to form a microcomposite, wherein the core substrate and the polymeric shell are formed from different materials. The system can demonstrate switchable behavior. The core substrate and the polymeric shell can be further modified, where modifications cooperate with each other to form the microcomposite. Also disclosed are formulations for fluid loss control and methods for controlling fluid loss in a well.
(FR)La présente invention a pour objet un système de régulation de la perte de fluide à deux composants comprenant un substrat central et une coque polymère coopérant l'un avec l'autre pour former un microcomposite, le substrat central et la coque polymère étant formés à partir de matériaux différents. Le système peut démontrer un comportement variable. Le substrat central et la coque polymère peuvent être en outre modifiés, les modifications coopérant l'une avec l'autre pour former le microcomposite. La présente invention concerne également des formulations pour la régulation de la perte de fluide et des procédés de régulation de la perte de fluide dans un puits.
