A Highly Mobile Drilling Rig Capable of Working Efficiently in Extreme Arctic Conditions
The Arctic Fox is a fully integrated, multi-module unit, configured in highway transportable loads for early ice road mobilization.
This lightweight rig design is crucial to early drillsite access, allowing for maximum over-the-hole drilling, extending the winter exploratory season by as much as 50%. The mast hoisting capacity is 400,000 lbs. with an eight-line hookup, and the substructure is capable of a simultaneous load of 281,000 lbs. for pipe set back, and 337,000 lbs. rotary table.
