Drilling Plastic Formations Using Highly Polished PDC Cutters

Drilling Plastic Formations Using Highly Polished PDC Cutters Authors R.H. Smith (Hughes Christensen Co.) have also provided important data for the proper geological applications and drilling practices that optimize drilling with PDC bits. Even though a PDC bit is deemed appropriate to the targeted formation, efficient, and thus economic, drilling performance
