<p>APPARATUS FOR PROVIDING A PACKAGED CORE A packaged core is obtained using a conventional core barrel system. A lining is provided in the core sample container of the core barrel. The core barrel is connected to a drill string extending into a borehole. As the drill string is rotated, the core sample moves into the sample container and inside of the lining. When the core barrel arrives at the surface, the sample core may be removed from the core barrel packaged in the lining. The core may be examined on site or the ends of the lining closed and the core completely packaged for shipment to the laboratory. -1a-</p> |
