Boart Longyear: LS 600

According to Boart Longyear, the LS 600 sonic rig delivers more accurate core sampling, less than 1 percent hole deviation, reduced waste and faster penetration than conventional methods. The rig’s technology incorporates sonic frequencies that match the resonant energy of the ground, allowing the core barrel to advance in unconsolidated and difficult overburden formations. During drilling, boreholes are cased continuously by first allowing the core barrel to advance into the substrate, followed by the outer casing. The LS600 can reach a drilling depth of up to 600 ft. The sonic head of the drill produces frequencies of up to 150 hertz through a robust oscillator assembly. An innovative air spring system protects the rig from extreme vibrations and redirects the energy down the drill string to the bit face.
