  • Description
  • Inquiry

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.

Our head assembly features long life span, good compatibility with parts like inner tube and outer tube from other vendors, and availability in all spare parts.

All with ISO certificate & quality control.
