Wireline Core Barrel Assemblies

The Wireline Core Barrel allows you to retrieve the core sample while continuing to drill; it’s not necessary to pull the drill string.

An overshot is lowered down on a wireline, latching onto the head of the core barrel, then the inner tube is pulled to the surface with the core sample intact.
