Depuis 5 ans, l’autoémulsification de l’eau dans les bruts a été reportée sur plusieurs systèmes, et associée une récupération améliorée du pétrole. Nous avons tenté de comprendre quelle était son origine physico-chimique. Nous avons constaté que lorsqu’on mettait en contact du pétrole brut avec de l’eau, il se formait alors des micro-gouttes d’eau dans l’huile pour toutes les huiles lourdes étudiées. Nous avons montré que le phénomène d’émulsification spontanée observé lors du contact de pétrole brut avec de l’eau de faible salinité est un mécanisme doublement osmotique, régit par la double pénétration d’eau et des espèces « osmogènes » (ie espèces générant de la pression osmotique) dans les gouttelettes d’eau. Puis nous avons montré que ...
