Great West Drilling’s AP1000 Becker Hammer Drills are designed for use when difficult drilling conditions are encountered. Alluvial deposits, glacial deposits, mine dumps, tailings piles and other challenging overburden formations are efficiently penetrated and accurately sampled using the Becker Hammer Dual Tube Reverse Circulation drill pipe.

Becker Penetration Tests for geotechnical investigations, liquefaction studies and pre and post ground improvement testing are accomplished using closed bits or knock out plug bits.

In consolidated formations, the AP1000’s rotary drives are used for Dual Tube Reverse Circulation air rotary drilling, HQ Wireline Coring, conventional air rotary and mud rotary drilling.
