Foothills Stand Alone Snubbing System

Class III System for Completions and Workover Programs

High Arctic Snubbing Services

The Foothills Stand Alone Snubbing System is High Arctic’s comprehensive equipment solution for efficient well servicing. This snubbing system stands apart in its class by providing additional well servicing equipment: a Class III BOP/accumulator system, pipe handling system, light plant, mud tank, and triplex pump.

With the Foothills’ inclusive features, you won’t need additional equipment to meet your service needs. This system’s overall efficiency is underscored by fast deployment – the Foothills can be moved on site, rigged up, and function tested for fast and immediate service.

When it comes to lift power and trip time, the Foothills can handle 120,000 pounds and 1 joint per minute; snub force is 70,000 pounds. The Foothills’ unique Load Management System allows wellbore work to be performed without transfer of extra weight to the wellhead. Safety features include an escape egress slide for quick exits, and a slip interlock system to prevent inadvertent slip openings.
