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).
Wireline Triple tube Core Barrels enable integral core recovery when drilling coal, clay bearing or highly fractured formations. The split tube retains the core sample in its received state for easier loading into sample trays or for storage and subsequent presentation to the geologist. The Triple tube Core Barrels is available in N, H and P sizes.
