ABSTRACT:
A device and method for forming a downwardly extending hole in the surface of the earth for seismic exploration or for forming a larger diameter hole such as made during exploratory drilling. The hole forming device includes an elongated rigid planting member having a point or tip at its lower end which is forced downwardly into the earth's surface by a combination of forces. The multiple forces may include a primary downward force exerting a substantially constant downward push on the planting member and either or both additional forces imparted to the planting member when the primary force no longer moves the planting member downwardly. The additional forces include a vibrating force applied to the planting member and a force formed by injection of high pressure low volume liquid into a subsurface formation from the lower end of the planting member to separate, saturate, liquefy or condition a compacted or resistant formation to enable penetration of a formation structure that resists penetration by the downward force.
