Capable of withstanding extreme conditions

The PathBreaker™ Whipstock with hydraulic anchor is made with high-performance tungsten carbide for fast cutting of all grades of casing.

One meter of anchor withstands 150 Klbs (70 t) of axial load. The minimum length for hydraulic anchor is 3m, providing an easy setting for the Whipstock.

Highly competitive and cost-effective technology

Pathbreaker™ Whipstock can be set in all inclinations (vertical, directional, or horizontal wells), allowing direct and reverse circulation while running in-hole. Its expandable profile anchor provides ultra reliable setting for the PathBreaker™ Whipstock at any depth.
