What is a sonic drilling rig?

A sonic drilling rig is unique in contrast to a standard rotary drill due to the sonic head at the helm of the rig. Within this sonic head are two rotating counterweights that produce a large amount of vibratory force, which becomes the resonance energy needed for the sonic drill to penetrate subsurface materials.

How does sonic drilling work?

When the sonic drilling equipment has been laid out on site and prepared for use, the core barrel penetrates first with the sonic head attached to begin drilling into the subsurface material. Once you’ve reached the desired depth to retrieve a sample, the casing can then be inserted over the core barrel to capture the sample.

Is sonic drilling a new technology?

At the time, sonic drilling was still a relatively new technology, and many in the industry were skeptical of its potential. But Geoprobe® saw the possibilities and invested heavily in developing a sonic head that could deliver powerful, precise drilling across a range of geological conditions.

How accurate is sonic drilling?

Sonic provides the most accurate installations of multi-point (CMT-type) wells where precise-depth installations are critical. Diameters as large as 12 inches are possible, and depths in excess of 850 feet have been reached. WHY CHOOSE SONIC DRILLING?

What is a sonic drilled borehole?

It is a low-impact technology that is safer by minimizing crew tool handling. By rotating and vibrating the rod, core barrel, and casing at sonic frequencies a clean borehole is drilled, cored and cased at the same time. A great deal of fewer cuttings are generated, saving time and money.
