Abstract

Vertical and/or directional drilling apparatus where compliant support (air bag, magnetic or the like) is provided for a vibrational head and drive assembly that carries the drill string. With the vibrational head having a shuttle from which vibration is not directly taken and with the compliant support allowing pull back in the directional mode several advantages arise.
