NTW HTW Diamond Core Barrel Backend Efficient Head Assembly

BTW NTW HTW Wireline Core Baarrel, Backend Efficient Wireline Surface Head Assembly

Wireline drilling is the special method of removing the core. When the driller wants to remove core from a conventional core drill, the entire core barrel has to be removed from the hole. This is time-consuming, as each rod has to be removed one at a time. With wireline drilling, a barrel of core can be removed from the bottom of the hole without removing the rod string. When the driller wants to remove the core, an overshot is lowered on the end of a wireline. The overshot attaches to the back of the core barrel inner tube and the wireline is pulled back and the inner tube disengages itself from the barrel.

Core sizes:

Advantages:

1. Faster coring at greater depths

2. Good stability due to constant diameter of the drill string

3. Excellent hydraulics

4. Good core recovery
