Sonic drilling involves the use of a dual line threaded drill pipe, with the inner line being advanced with a core barrel attached to it. The LS™250 MiniSonic™ from Boart Longyear is a compact sonic rig that provides a continuous, relatively undisturbed core sample through any type of formation. When using the iso-flow groundwater profiling system, hydrogeological and geochemical data can be easily obtained. Drill spoils and waste are reduced by up to 80 percent compared to other methods. Safety features include an interlocked rotation barrier, reduced noise levels, a dump mast and wiggle tail, and a rod presenter.
