Abstract

New bit technology was used to create a series of steel body bits which incorporate proven PDC bit design features for improved performance. The bits have achieved field records in fully one-third of the applications in which they were introduced. The technology described includes all aspects of bit application, including new manufacturing processes, advanced design engineering, a unique nozzle configuration and use of a computerized rock compressive strength analysis program to refine application.

Field performance of steel body PDC bits is detailed and compared to conventional matrix body bits to illustrate the resulting performance improvements possible with proper steel body PDC bit application.
