Experimental Study on Force of PDC Cutter Breaking Rock

Applied Mechanics and Materials, 2014
Because the anisotropy of shale formation should result in that wellbore deviations is unpredictable, the bit-rock interaction should be fully lucubrated in order to eliminate this problem. The impact of shale rock anisotropy and the cutting velocity on the load of PDC cutter wasn’t considered by the existing cutter-rock interaction models.

Influence of polished PDC cutters in rock cutting

2002
This paper reports the results of an experimental investigation aimed at understanding the in?uence of the polishing of the cutter face on the magnitude and orientation of the force mobilized during rock cutting. An extensive series of tests were conducted in several rock specimens using the Rock Strength Device, using both standard and polished ...

A new procedure to analyse the wear of PDC cutters

2006
Ongoing research at the Faculte Polytechnique de Mons focuses on determining the processes and parameters which control the cutting response of worn cutters. In particular, this paper presents a new approach under development for understanding wear mechanisms by continuously analysing the evolution of wear in term of cutting efficiency.

Single Cutter Testing – A Key for Pdc Bit Development

SPE Offshore Europe, 1987
Abstract A description is given of a single-cutter tester for studying the cutting process of PDCs in rock under simulated downhole conditions. The use of the tester is illustrated by a study of the effect of downhole pressures on the cutting process in shales.
