Seismic drilling is very similar to mining drilling in that commonly, a blast hole or shot hole is drilled and explosives are lowered into it. But the purpose of seismic drilling is actually a form of exploration drilling. The blast can give single or continuous pulses of sound energy which travel through various geological layers producing lithography of the underground formations. In addition to blasting there are seismic profiling techniques that use the noise generated by the drill bit to obtain ground readings. This form of exploration drilling is commonly done to identify petroleum sites or other mineral deposits. Western Drilling Tools supplies many of the drilling tools required for seismic drilling. We offer seismic drilling equipment, seismic drilling tools and everything for custom drilling tools.
