Wireline Triple Tube Core Barrel (B W/L3), 33.5 mm

Features

• Wireline core barrels are used when coring to greater depths, mainly because they eliminate the need to couple and uncouple the rod string each time the core is retrieved
• An overshot device is dropped on a cable and directly couples onto the inner tube assembly, allowing fast retrieval of the core after each core run
• The double tube wireline core barrel is converted to triple tube by incorporating a split steel tube inside the inner tube
• In addition, a piston and pump-out adaptor is provided for pumping out the split steel tube when it is full of rock core
