The NaviGATOR
Improves the probability of casings and liners reaching TD when rotation cannot be applied

The NaviGATORô 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 tool, which can be used on cemented or un-cemented casing strings, completions, liners and sand control screens, is simple to install and improves the probability of casings, liners and other open hole deployed systems reaching planned TD.

Variants:

NaviGATOR with Shoe
The NaviGATOR with shoe sees the shoe placed below the tool so that the relative rotational motion from reciprocation can be used to orientate the nose over or past obstructions.
