Wireline Double Tube Core Barrels BQ NQ HQ PQ NQ3 HQ3 PQ3

 

Wireline core drilling equipment is very commonly used for mineral exploration for deep holes because of practical usage. 


Wireline double tube core barrels are primarily used in deep coring. With an overshot device, they eliminate the need to couple and uncouple the rod string each time the core is retrieved.
