| 20110100631 | FLOODING FLUID AND ENHANCING OIL RECOVERY METHOD - The invention relates to an enhancing oil recovery method by injecting into a subterranean oil formation an aqueous flooding fluid comprising at least one injecting galactomannan polymer substituted by at least one sulfonation agent. The invention also relates to an flooding fluid having better injectivity properties than existing flooding fluids. | 05-05-2011 |
| 20120085534 | Viscoelastic composition with improved stability - The present invention relates to a method for the enhanced recovery of oil from an underground formation, in which a viscoelastic aqueous fluid comprising at least one viscosifying zwitterionic surfactant is injected into the said formation and the said fluid is conducted through this formation in order to displace the oil from the formation and to recover it via a different point from that where the viscoelastic aqueous fluid was introduced, characterized in that the said fluid exhibits an amount of a base sufficient to bring its pH to a value of greater than 10, preferably of between approximately 11 and 13. | 04-12-2012 |

| 20090232942 | Yeast Preparations With Improved Antioxidant Properties and Uses Thereof - The invention concerns yeast preparations having improved antioxidant properties, characterized in that they comprises yeasts concurrently enriched in glutathione and selenium, by at least 15 mg/g of dry matter and selenium by at least 500 ppm advantageously of the order of 2000 ppm. The invention is applicable as antioxidant additives, in particular as foods or nutrients, or functional foods for humans and animals and in cosmetics. | 09-17-2009 |
| 20100092611 | COATED DRIED ACTIVE YEASTS AND FOOD PRODUCTS CONTAINING THE SAME - The invention relates to yeasts comprising a protection coating made of one or more compounds which are inert relative to said yeasts, characterised in that the yeasts are dried active yeasts. Application in the preparation of food products for animals. | 04-15-2010 |
