The High Arctic Rig Assist Snubbing Unit is a truck mounted hydraulic system that can be used on most well servicing and drilling rigs. The Rig Assist Snubbing Unit works in conjunction with the other services on location to manage the well while it is underbalanced. The system function is to run and/or remove pipe with hydraulic rams at a reasonable rate during underbalanced well conditions. Since the Rig Assist Snubbing Unit is a modular unit, it can be rigged up in as little as one hour. The Rig Assist Snubbing Unit is typically contracted on a day-to-day call out basis to snub assist a workover rig in underbalanced operations as requested by a customer. Two employees drive the Rig Assist Snubbing Unit to the location and rig it on to the well to assist the workover rig in the movement of tubing under pressure (snubbing).
