ABSTRACT:
In combination with resonant sonic earth drilling components, and for particular use in retrieving a core sample in a core barrel seated against an internal shoulder in a sonically driven drill bit, a resilient axial loading device not only urges the bottom of the core barrel into continuous contact with the seat but also cushions the core barrel from the sonic energy in the drill bit, thereby minimizing damage to the core sample.
