Recent developments in drill bit technology. [Stratapax and roller cone bits]

Technical Report ·
OSTI ID:5948898
The drilling environment in deep oil and gas wells and in geothermal wells is generally hostile. Formation temperatures of 150 to 350/sup 0/C are commonly encountered. New developments in drilling technology are required to reduce the cost of drilling wells under these conditions. In the United States, the Department of Energy is funding research directed at assisting industry in developing the techniques required for drilling in hostile environments. Among the most recent developments in high temperature drill bits are the use of Stratapax cutters in drag-type bits and the use of improved, high-temperature materials in conventional roller cone bits. The paper describes recent developments in these two areas.
