• Wellsite Stabilization

    We offer a range of stabilization options to mitigate mechanically induced damage to the recovered core. This damage happens where an annulus occurs between the recovered core and the inner barrel, allowing movement of the core if not filled. Our stabilization options provide a means of filling this annular space to protect the core from damage. A variety of different fillers can be used, allowing the operator to choose the best solution based on the lithology of the core and the project objectives.

    Foam
    Foam is a versatile solution, providing a means of securing rock types where there is likely to be non-continuous annular space. It is the most popular technique currently used and is suitable for a wide range of rock types. Foam can be applied to either the full 9 m inner barrel or when 1 m sections have been cut.

    Resin
    Resin is ideal for securing truly unconsolidated material. The low initial viscosity allows for easy penetration of all voids, ensuring maximum stabilization with minimal grain disturbance. Inner barrel and core material need to be slabbed open to access the core material using this method.

    Gypsum
    Used in the plaster form, CaSO4ยท1/2H2O, gypsum is a popular method of annular fill and a benign alternative to foam. Made with readily available materials, this inorganic material secures the core against potential chemical alterations and reactions that can occur with some resins and foams.

    Plastic Strip
    Plastic strips are a simple, economical solution suitable for robust material where an annulus exceeds 2 mm. They are ideal for remote locations as there are no transportation or shelf life restrictions.
