• Non-Rotating Inner Barrel Stabilizers (NRIBS)

    Our non-rotating inner barrel stabilizers (NRIBS) permit the safe and efficient recovery of the core at the surface, and they eliminate any potential for the transmittal of damaging torque to the core during the inner barrel separation process. The NRIBS contain a window that provides easy access for a core guillotine to shear the core, minimizing stress on the surrounding structure. In addition, our NRIBS are designed to retain the core in place before the inner barrel sections are fully separated on the rig floor, providing additional core security.

    Our non-rotating inner barrel stabilizers (NRIBS) permit the safe and efficient recovery of the core at the surface, and they eliminate any potential for the transmittal of damaging torque to the core during the inner barrel separation process. The NRIBS contain a window that provides easy access for a core guillotine to shear the core, minimizing stress on the surrounding structure. In addition, our NRIBS are designed to retain the core in place before the inner barrel sections are fully separated on the rig floor, providing additional core security.

    While downhole, the NRIBS centralize and stabilize the inner barrel within the outer assembly, protecting the inner barrel from damaging torque during the coring process. This stabilization minimizes the potential for core jamming and protects the core from mechanical damage. The NRIBS also prevent sagging of the inner barrel in deviated holes, allowing extended core runs. 

     

    Features/Benefits

    Inner Barrel Stability – Stabilizer ring prevents downhole inner barrel rotation, reducing the risk of inducing fractures to the core material
    Improved Core Quality – Allows surface disassembly without rotation
    Liner Compatibility – Options for use with inner barrel liner systems
    Gamma Options – Low-attenuation aluminum option eliminates core gamma blind spots
    Increased Safety – Allows for safe inner barrel separation and controlled release of any trapped gas that may have accumulated at these points
