Effect of Back Rake Angle and Shape of PDC Cutter On Wear Rate In Hard Formation
This project aimed to investigate the effect of cutter back rake angle and shape of cutter on Polycrystalline Diamond Compact (PDC) cutter wear rate in hard formation application. PDC bits are widely used to drill soft formations in petroleum industry due to their excellent Rate of Penetration (ROP)...
