Title

INVERTIBLE WATER-IN-OIL LATICES AND METHODS OF USE
(FR)
LATEX RÉVERSIBLES EAU-DANS-L'HUILE ET LEURS PROCÉDÉS D’UTILISATION
Abstract:
(EN)
Invertible latices suitable for use in enhanced oil recovery are formed by adding a first inversion surfactant and a second inversion surfactant to a water-in-oil latex comprising about 15 wt% to 50 wt% of a water soluble polymer having a net ionic charge. The first inversion surfactant has a hydrophilic/lipophilic balance of about 15 to 35 and an ionic charge that is the opposite of the net ionic charge of the polymer. The second inversion surfactant has a hydrophilic/lipophilic balance of between about 8 and 20. The invertible latices are diluted in a single step to provide dilute latices having 10,000 ppm or less polymer solids.
(FR)
La présente invention concerne des latex réversibles devant être utilisés dans la récupération améliorée de pétrole et formés en ajoutant un premier tensioactif d'inversion et un second tensioactif d'inversion à un latex d'eau-dans-l'huile comprenant environ de 15 % en poids à 50 % en poids d'un polymère soluble dans l'eau ayant une charge ionique nette. Le premier tensioactif d'inversion présente un équilibre hydrophile/lipophile d'environ 15 à 35 et une charge ionique qui est opposée à la charge ionique nette du polymère. Le second tensioactif d'inversion présente un équilibre hydrophile/lipophile compris entre environ 8 et 20. Les latex réversibles sont dilués en une étape unique pour fournir des latex dilués ayant 10 000 ppm ou moins de matières solides polymères.
