  • Composition containing a surface active compound and glycolipids and decontamination process for a porous medium polluted by hydrocarbons
    Patent number: 5654192
    Abstract: The invention relates to a decontamination process for a porous medium polluted by hydrocarbons according to a composition containing a surface active agent as glycolipids in their crude or modified form is introduced, for example by at least one input well, in the optional presence of hydrocarbon-destroying bacteria and at least one part of the composition containing at least one part of the hydrocarbons is collected, for example by a production well.
    Type: Grant
    Filed: June 5, 1995
    Date of Patent: August 5, 1997
    Assignee: Institut Francais du Petrole
    Inventors: Jean Ducreux, Daniel Ballerini, Marc Baviere, Christian Bocard, Nicole Monin
  • Process for washing solid particles comprising a sophoroside solution
    Patent number: 5326407
    Abstract: The invention relates to a process for cleansing solid particles impregnated with hydrocarbons. The process implements a solution comprising sophorosides. The process is particularly intended for washing cuttings impregnated with a drilling fluid containing hydrocarbons.

    Assignee: Institut Francais du Petrole
    Inventors: Marc Baviere, Didier Degouy, Jacqueline Lecourtier
  • Micellar systems containing N-acyl N-alkyl .alpha.-amino-carboxylic compounds, particularly useful in enhanced hydrocarbon recovery
    Patent number: 4686053
    Abstract: In the preparation of miceller systems for enhanced hydrocarbon recovery, surfactants are used which consist of N-acyl N-alkyl-.alpha.-amino-carboxylic compounds. The considered products comply with the general formulas: ##STR1## wherein at least one of R.sup.1, R.sup.2 and R.sup.3 is a saturated or unsaturated C.sub.1 -C.sub.22 aliphatic hydrocarbon radical (one of them having optionally a carboxylic group) the other or others being a hydrogen atom, R.sup.1, R.sup.2 and R.sup.3 having together from 4 to 22 carbon atoms, R.sup.4 is an alkyl radical of 1-5 carbon atoms, R.sup.5 an alkyl radical of 1-12 carbon atoms and M is an alkali or alkaline-earth metal, ammonium or a quaternary ammonium group.As used in the formation of micellar systems (aqueous solutions, emulsions or mirco-emulsions) for enhanced oil recovery, these surfactants have improved performances, particularly, in field waters of high polyvalent ion (Ca.sup.++ and Mg.sup.++) content, within relatively wide temperature and pH ranges.

  • Enhanced oil recovery process by injecting a micellar solution of surfactants having a solubility gradient in water
    Patent number: 4648451
    Abstract: A process for the enhanced oil recovery in oil reservoirs having a significant cation exchange capacity. A displacement slug is injected into an injection well formed from several successive zones, the solubility in the injection water of the anionic surfactant which it contains being adjusted so as to increase, for compensating the rock-micellar solution interactions, from one zone of the slug to the next considering the order of introducing the different zones of the slug.
