AbstractA conceptual drilling technology called Vibration Assisted Rotary Drilling (VARD) was experimentally investigated in this study. Similar drilling technologies and their mechanisms were reviewed during this investigation. A laboratory experimental drilling system was developed. This system is capable of providing basic controls over most drilling operating parameters; it is also capable of providing vibrations with adjustable amplitudes near the bit. Relationship between the Weight on Bit (WOB) and Rate of Penetration (ROP), and the effect of drilling fluids were investigated. VARD experiments on coring and full face diamond impregnated bits were then conducted. The effects of vibrations with various amplitudes on the conventional WOB-ROP relationship were studied and discussed.
