Title (EN) HIGH STABILITY POLYMER COMPOSITIONS WITH SILOXANE POLYETHER COMPOUNDS FOR ENHANCED OIL RECOVERY APPLICATIONS
(FR) COMPOSITIONS POLYMÈRES À STABILITÉ ÉLEVÉE COMPRENANT DES COMPOSÉS SILOXANE POLYÉTHER POUR DES APPLICATIONS DE RÉCUPÉRATION ASSISTÉE DU PÉTROLE
Abstract:
(EN) Liquid polymer and inverse emulsion compositions comprising: one or more hydrophobic liquids having a boiling point at least about 100 °C; one or more acrylamide- (co)polymers; one or more emulsifier surfactants; one or more inverting surfactants; and one or more siloxane polyether compounds. When the composition is inverted in an aqueous solution, it provides an inverted solution having a filter ratio using a 1.2 micron filter (FR1.2) of about 1.5 or less.
(FR) L'invention concerne des compositions de polymère liquide et d'émulsion inverse comprenant : un ou plusieurs liquides hydrophobes ayant un point d'ébullition d'au moins environ 100 °C; un ou plusieurs (co)polymères acrylamide; un ou plusieurs tensioactifs émulsifiants; un ou plusieurs tensioactifs d'inversion; et un ou plusieurs composés polyéther de siloxanes. Lorsque la composition est inversée dans une solution aqueuse, l'on obtient une solution inversée ayant un taux de filtration, à l'aide d'un filtre de 1,2 micron (FR1,2), inférieur ou égal à environ 1,5.
