  • ULTRA LONG-LASTING MAKE-UP FOUNDATION
    Publication number: 20230058262
    Abstract: The present invention relates to a cosmetic make-up composition for the skin in the form of a water-in-oil (W/O) emulsion comprising in a physiological acceptable medium at least: a) an aqueous polyurethane dispersion, b) a hydrophobic film-forming polymer, c) one or more volatile hydrocarbon oils, preferably in an amount of at least 10 wt % relative to the total weight of the composition, d) one or more absorbent fillers having an oil uptake greater than or equal to 30 ml/100 g and e) pigments.

  • Method of modelling enhanced recovery by polymer injection
    Patent number: 8146659
    Abstract: The present invention relates to an optimized method for modelling flows in a geological hydrocarbon reservoir, comprising injecting an aqueous polymer solution to sweep the hydrocarbons, determining a relationship between a parameter linked with the mobility reduction of the solution in the reservoir and the water saturation, and accounting for this relationship in a flow simulator to achieve modelling.
    Type: Grant
    Filed: April 22, 2009
    Date of Patent: April 3, 2012
    Assignee: IFP
    Inventors: René Tabary, Laurent Neau, Matthieu Olivaud
  • Method and device for analyzing the COcontained in a drilling fluid
    Patent number: 7666679
    Abstract: A method for estimating the quantity of CO2 present in a geologic formation and a device for implementing the method include the steps of penetrating the formation by a well drilled from the surface contacting formation with a fluid that travels from the formation to the surface sampling a given quantity of return fluid at the surface and transferring it to a cell, ensuring the pH of the quantity of fluid, adding a given quantity of product acidifying the fluid to adjust the pH to a value of less than 4, and measuring the CO2 level of the gas in the cell after the acidification step.
