Rig Assist Snubbing Unit

Managing Underbalanced Wellbore Conditions As-Needed

High Arctic Snubbing Services

High Arctic’s Rig Assist Snubbing Unit is a truck-mounted hydraulic system that can be used on most service and drilling rigs to manage underbalanced wellbore conditions.

Typically, the Rig Assist Snubbing Unit is contracted to work on snubbing operations as needed. Its modular design means that rig up is fast and efficient. In most cases the rig requires just one lift to set the unit in place.

The Rig Assist Snubbing Unit utilizes hydraulic rams to efficiently handle pipe. Lift power and snub force is 120,000 pounds and 70,000 pounds respectively.
