DR - Navigator
Inclination and Gamma at Bit Motor

Specifications

DR-Navigator provides real-time gamma ray information and inclination measurements directly behind the bit, giving you the best information possible when making directional steering decisions. It enables you to adjust instantly to formation and dogleg changes along the well path and make corrections ultimately reducing your drilling risks.

 


ADVANTAGES

Faster Geo Steering Adjustments
More Accurate Drilling Control to Reduce Dog Legs
Optimized Well Placement
Reduced Well Tortuosity and Dogleg Severity
Reduced of Time-Drilling during Sidetracking
