Improve the probability of casings and liners reaching TD when rotation cannot be applied.

Rubicon’s NaviGATOR tools play a crucial role in rotating the end of casings and liners and avoiding obstructions. This dramatically improves the probability of casings and liners reaching planned TD when rotation cannot be applied. The NaviGATOR is a casing-based tool that ratchets and rotates the end of a casing or liner string by reciprocating the pipe. A casing reamer shoe or guide shoe with an eccentric profiled nose can be placed below the tool so that the relative rotational motion from reciprocation can be used to orientate the nose over or past obstructions. The NaviGATOR can be used on cemented or un-cemented casings strings, completions, liners and sand control screens.

Making it better

The NaviGATOR is simple to install. Improves the probability of casings, liners, and other open hole deployed systems reaching planned TD.

Has no components to drill out other than the eccentric aluminum nose, therefore reducing drilling inside casing time. Protects BHA. Provides improvement in operational efficiency.


Available in most standard casing/liner versus open-hole combinations

Drill out ID matches casing being run

Flow by areas have been maximized for circulation and cementation

Strength to suit casing specifications

Supplied with customer specified casing connections

Continuous ratchet with higher strength than connection

Can be provided with either a SLICK body or a REAMING body
