R-22 Canterra CT 312 Discoverer

The Canterra CT 312 Discoverer is equipped with a sliding angle derrick, driven by a Detroit 350 H.P. Tier 2 engine. Rig has a powerful multipurpose top head with tilt out loading function. Drill is capable of 1000 foot depths with 4-inch matrix light weight dual wall pipe. Drill is mounted on a Foremost Canterra Articulated Buggy with travel speeds of 20 mph depending on terrain. Drill exerts minimal ground pressure minimizing disturbance with its low weight and narrow width. It also works well in heavily forested areas due to its low height, small foot print and easy turning in close quarters. The Canterra Discoverer Jumbo Drill Style mast pivots to both sides of the buggy allowing the driller a 180-degree arc as well as vertical angle drilling directly behind the buggy. This ability allows us to minimize pads and work from existing forest service or BLM fire access roads. Drill is 8 feet 6 inches wide and thirty feet long pivoting in the middle. It weighs under 30,000 lbs. A separate compressor is utilized , either a 900 x 350 on a rubber track or a 500 x 350 on a small buggy depending on project depth.
