New steel body PDC bit technology is shown to enhance drilling performance in a range of applications previously limited to matrix body bits. Specific aspects of the technology are &taile& including various proven desigm features, and unique manufacturing and materials treatment. In addition. the paper addresses the impact of increasing energy available at the bit face through utilization of a new hydraulic jet technology in combination with the advanced features of steel body PDC bits. Case histories are included to describe the application range of the new steel body bits, in terms of Mh drilling performance and economic impact.
