Title (EN) COMPOSITION, METHOD AND USE FOR ENHANCED OIL RECOVERY
(FR) COMPOSITION, PROCÉDÉ ET UTILISATION POUR LA RÉCUPÉRATION ASSISTÉE DU PÉTROLE
Abstract:
(EN) Disclosed herein are compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations (tight shale reservoirs). The flowback compositions include an anionic dimer surfactant, an anionic monomer surfactant, and a demulsifier. The flowback compositions convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations. The flowback composition are useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.
(FR) L’invention concerne des compositions et des procédés pour améliorer la récupération ou le reflux de composés d'hydrocarbures à partir de formations rocheuses souterraines fracturées contenant des hydrocarbures (réservoirs étanches d’argile schisteuse). Les compositions de reflux comprennent un tensioactif dimère anionique, un tensioactif monomère anionique et un désémulsifiant. Les compositions de reflux convertissent les roches imprégnées de pétrole en roches imprégnées d'eau tout en présentant une faible tendance des constituants de la composition à pénétrer par sorption dans la roche. Les compositions de reflux ne provoquent pas la formation d'émulsions avec des composés d’hydrocarbures dans les formations rocheuses souterraines fracturées. Les composition de reflux servent à augmenter le rendement d'hydrocarbures récupérés à partir de réservoirs étanches d’argile schisteuse,
