Sonic drilling is capable of high speeds as well as continuous coring. MSD sonic rigs are similar in appearance to conventional air or mud rotary drill rigs. The difference is in the drill head, which is slightly larger and contains the mechanism needed for rotary motion, as well as an oscillator, which causes a high frequency force on the drill string. The drill bit physically vibrates up and down in addition to being pushed downward and rotated. These three combined forces allow drilling to proceed rapidly through most geological formations including most types of rock.
MSD can provide SPT and CPT testing with sonic drill rigs.
