DRILLING TOOLSWIRELINE CORE SAMPLING SYSTEMFOR MINERAL EXPLORATION AND SOIL INVESTIGATION

J Series Core Barrel

NLC is the manufacturer who produces genuine / original wireline tools.

Wireline coring allows rapid placement and withdrawal of the

core barrel inside the wireline rods. Therefore, the rods do not

need to be pulled out from a bore hole to take out a core sample

inside the core barrel. Only Inner Tube is cought with Overshot

and pulled out to the surface with wire.

The overshot, attached to the winch by a steel cable, is lowered

down inside the rods. When it reaches the back of the core

barrel, it latches on to it and disengages it from the drill rods, the

winch then pulls the complete barrel and its core sample to the

surface.
