Title (EN) WATER-IN-OIL MICROEMULSIONS USEFUL FOR OIL FIELD OR GAS FIELD APPLICATIONS AND METHODS FOR USING THE SAME
(FR) MICRO-EMULSIONS EAU DANS HUILE UTILES POUR DES APPLICATIONS SUR DES CHAMPS DE PETROLE OU DE GAZ
Abstract:
(EN) A microemulsion comprising (i) an oil phase, (ii) an aqueous phase comprising an aqueous solution of a water soluble oil field or gas field production chemical or an aqueous dispersion of a water dispersible oil field or gas field production chemical and (iii) at least one surfactant, wherein the aqueous phase is distributed in the oil phase in the form of droplets having a diameter in the range 1 to 1000 mn or in the form of microdomains having at least one dimension of length, breath or thickness in the range 1 to 1000 nm.
(FR) La présente invention concerne une micro-émulsion qui comprend (i) une phase huileuse, (ii) une phase aqueuse comprenant une solution aqueuse de produit chimique issu de champ de pétrole ou de gaz soluble dans l'eau ou une dispersion aqueuse de produit chimique issu de champ de pétrole ou de gaz que l'on peut disperser dans l'eau, et (iii) au moins un tensioactif. La phase aqueuse est répartie dans la phase huileuse sous forme de gouttelettes d'un diamètre allant de 1 à 1000 mn ou sous forme de microdomaines possédant au moins une dimension de longueur, de largeur ou d'épaisseur allant de 1 à 1000 nm.
