PDCs were first introduced decades ago as a replacement for natural diamonds. These early cutters lacked toughness, were generally limited to the softest drilling applications, and required very specialized bit designs and carefully controlled drilling parameters. Over the years, aggressive innovation and improvements to the process have steadily increased the durability, impact resistance and abrasion resistance of PDCs.
Today’s PDCs are effective in shale, limestone, and sandstone formations. Over time, the PDC-drillable zone will continue to grow and expand (see figure). For example, US Synthetic frequently cuts crystalline rocks for extended periods in a laboratory environment—and is working hard to extend these capabilities to an operating environment.
Today, PDC enhanced bits provide the fastest, most durable and most cost-effective drilling.
