Abstract
A vibration system for drill bit housing and method is disclosed, which may be utilized to assist in lowering a drill string into a wellbore through which drilling fluid is pumped. In one embodiment, a drill bit housing contains a symmetrical rotatable member positioned to rotate in response to drilling fluid pumped through the housing, whereby a mechanical interconnection connected to the rotatable member produces vibrations within the drill bit housing for advancing bottom hole assemblies.
