Abstract

Une formule d'acidification à utiliser dans la stimulation de la production d'hydrocarbures est stable lorsqu'elle est emballée et stockée en tant que fluide unique pendant des périodes dépassant un an. La formulation contient un solvant de miscibilité qui empêche en grande partie toute séparation de phase entre les composants et le manque de dispersion des additifs dans le fluide.
