PCD Bearings – Current Applications

• Drilling motors (oil and gas)

– Approximately 20 years in this application with resurgence in the past 3 years

– High-load and high-speed applications

– Drilling mud-lubricated

– Replace conventional drilling mud-lubricated ball bearings

• Drilling turbines (oil and gas)

– Approximately 30 years in this application

– Often high well temperatures

– Drilling mud-lubricated

• Other oil and gas drilling tools

– Drilling mud-lubricated

Requirements for Bearings in Geothermal

and Deep Drilling Applications

• High temperature – up to 300 C

• Harsh environments

• Long mean-time between failure (costly to replace tools and/or components)

• Some friction is allowable? – depending on application


• PCD bearings are currently used extensively in oil and gas drilling applications including those in deep and hightemperature wells

• PCD bearings are very likely suitable for many processlubricated geothermal drilling and production applications

– Each application must be judged on its own merits (including axial loads, speeds, and cooling conditions)

• PCD bearings perform well in a wide range of operating conditions including boundary, mixed-mode, and

hydrodynamic lubrication regimes

• New PCD bearing configurations give tool manufacturers design flexibility
