Cascade - Sonic Drilling Rig Brochure

Sonic technology is ideal for both deep and shallow drilling applications where undisturbed core sampling through almost any type of geological formation is required.   This powerful technology provides many advantages over other types of drilling techniques. 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 less cuttings are generated, saving time and money. Continuous cores are produced using a single tube core barrel and an override casing.
