    This training course presents the Chemical Enhanced Oil Recovery
    (CEOR) methods available in the Eclipse simulator.

    When using CEOR, chemicals such as surfactants, alkaline solutions, and polymers are added to the displacing water. This changes the physicochemical properties of the water and the contacted oil, making the displacement process more effective. The three main approaches are the use of surfactants, alkaline, and polymers.

    In surfactant flooding, the interfacial tension between the oil and the displacing water, and the interfacial tension between the oil and the rock interfaces are reduced so that residual oil can be displaced and recovered.

    In alkaline flooding, the reaction of the alkaline compounds with the organic acids in the oil forms in situ natural surfactants that lower the oil-water interfacial tension. Polymers are used to increase the viscosity of the displacing water to improve the oil sweep efficiency.

    Examples using these different reovery methods are further covered using Eclipse.

     
    Day 1

    Enhanced Oil Recovery fundamentals

    • Improved oil recovery versus enhanced oil recovery
    • Chemicla EOR processes
    • Screening criteria for chemical EOR processes

    Polymer flooding

    • General information on polymer flooding
    • Polymer chemistry
    • Polymer flow behaviour in porous media
    • Polymer models in Eclipse

    • General information on alkalis
    • Alkaline model in Eclipse
    • Summary of Alkaline model Eclipse keywords
    • Field applications of Alkaline-Surfactant-Polymer flooding

    On day two of the course participants are taken through the Surfactant flooding and the ASP flooding methods of the CEOR simulation process and workflow, along with examples and problems to help the participants use the knowledge obtained throughout the day.

    Day 3

    Foam flooding

    • General information on foam
    • Flow of foams in porous media
    • Foam model in Eclipse
