Abstract:
The inner barrel system includes a coring inner barrel. The system also includes a connector sub coupled to the coring inner barrel. The connector sub includes a tubular wall defining a central axis and a shear zone extending longitudinally along at least a portion of the tubular wall. The shear zone severs with less force than the coring inner barrel.
