Standard Wireline Double tube Core Barrels are ideal for use in most of the drilling conditions and are available for application in standard hole sizes (BWL, NWL, HWL and PWL).
When the inner-tube is full, a device called an overshot is lowered down the hole via a wireline cable and brought to the surface by use of a winch.
A Overshot is available for each size of core barrel. This is the retrieval device lowered on the wireline to recover the inner tube assembly containing core.
