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

Rubicon’s NaviSHOE series tools aid in rotating the end of casings and liners to reach planned TD. The NaviSHOE tool converts simple casing reciprocation into an indexing rotation at the tool allowing it to orientate the nose over or past obstructions anywhere in the well. The NaviSHOE offers the flexibility to run on cemented or un-cemented casing strings, completions, liners and sand control screens. This tool is run as a replacement for your standard float or guide shoe.

Making it better

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

Offers fast drill out. Has no components to drill out other than the eccentric aluminum nose, therefore reducing drilling inside casing time and protecting BHA.
