NaviSHOE for Deepwater Well Construction 
Maximize drilling efficiency in deepwater well construction projects where conventional rotation methods face operational constraints. The NaviSHOE converts reciprocation into precise downhole rotation for complex deepwater geometries.
The 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. 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.
