Title
(EN) SOLVENT-INDUCED SEPARATION OF OILFIELD EMULSIONS
(FR) SÉPARATION INDUITE PAR SOLVANT D'ÉMULSIONS DE CHAMP PÉTROLIFÈRE
Abstract
(EN)
Systems and methods for separation of oleaginous fluids, aqueous fluids, and solids from drilling or other oilfield emulsions by solvent extraction. A method for separation of oilfield emulsions comprising: providing an oilfield emulsion prepared for use in a wellbore and/or recovered from a wellbore; mixing the oilfield emulsion with at least a solvent to form at least a mixture; and separating the mixture to at least partially recover an oleaginous phase of the oilfield emulsion.
(FR)
L'invention concerne des systèmes et des procédés permettant la séparation de fluides oléagineux, de fluides aqueux, et de solides provenant d'émulsions de forage ou d'autres émulsions de champ pétrolifère par extraction par solvant. L'invention concerne également un procédé permettant la séparation d'émulsions de champ pétrolifère comprenant les étapes consistant : à fournir une émulsion de champ pétrolifère préparée pour une utilisation dans un puits de forage et/ou récupérée à partir d'un puits de forage ; à mélanger l'émulsion de champ pétrolifère avec au moins un solvant pour former au moins un mélange ; et à séparer le mélange pour au moins partiellement récupérer une phase oléagineuse de l'émulsion de champ pétrolifère.
