Title (EN) PROCESS
(FR) PROCÉDÉ
Abstract:
(EN) The invention relates to a process for demulsifying an emulsion comprising oil, water and a water-soluble polymer, said process comprising contacting the emulsion with a multivalent metal-containing compound (e.g. an inorganic trivalent metal salt such as aluminium chloride). This process is particularly suitable for use in enhancing recovery of crude oil from emulsions of polymer enhanced oil recovery floods used to maximise the production of crude oil from reservoirs.
(FR) L'invention concerne un procédé permettant de désémulsionner une émulsion comprenant de l'huile, de l'eau et un polymère soluble dans l'eau, ledit procédé consistant à mettre l'émulsion en contact avec un composé contenant un métal multivalent (par exemple un agent de sel de métal trivalent tel que le chlorure d'aluminium) Ce procédé est particulièrement utile pour améliorer la récupération de pétrole brut à partir d'émulsions de polymères de récupération assistée du pétrole à injecter utilisées pour maximiser la production de pétrole brut à partir de réservoirs.
