Analysis of Fixed Cutter Bit for Directional Drilling in Hard Formation
Polycrystalline Diamond Cutters (PDC) are widely used in today’s drilling activities as challenging environments which consist of HPHT wells, directional drilling implementation and deep-water drillings arise to the occasion at more frequent rate than ever. These harsh conditions have proven a mar...
