Commander PDC bits Used Dark Matter Cutters High Penetration Drilling Deeper Holes


 

Commander PDC bits offer improved directional control and steerability at a higher rate of penetration. DARK MATTER cutters stand up better to drilling the deeper holes at longer intervals due to high thermal resistance.

Standard bits can be easily disrupted by the dynamic instabilities of directional or lateral drilling, but Atlas Copco Secoroc COMMANDER PDC bits feature a patented discontinuous seven-blade bit design to address these factors with improved performance.
 

Finding a bit that offers both good steerability and good ROP can be a difficult proposal. In theory, more blades offer more stability and by extension better ability to control and steer the bit. However, more blades typically also means more cutter contact with the formation, which equates to slower drilling. The curve and lateral sections of a well can cause drillers to reduce the rate of penetration (ROP) to preserve the tool face or risk having to trip out of the hole. Standard PDC inserts with their high abrasion-resistant cutting edges may be suitable for a number of oilfield applications in general. In applications that generate higher heat, however, the cobalt present in a standard PDC insert acts as a catalyst to sinter the diamond-to-diamond bond, unitizing the diamond layer to the tungsten carbide substrate.
 

Roschen used proprietary software to model how the bits function under a variety of drilling challenges such as rotating off center axis and abnormal force absorption. COMMANDER PDC Bit Series demonstrated up to 35 percent improvement in stability in off center axis drilling situations with a 29 percent improvement in stability for abnormal force absorption.
 

Heat generated by friction during the drilling process can causes cobalt in the cutters to expand at a higher rate than diamond. Thermal stress in the diamond table increases until the structure breaks down. The cobalt between the diamond crystals expands and breaks the diamond-to-diamond bonds. The result is reduced cutter life and premature cutter failure.
 

Patent protected deep-leaching technology selectively removes cobalt from the diamond table of the PDC cutter. Leaching increases cutter thermal stability, which reduces damage to the cutter and extending bit life in difficult and abrasive formations.

Starting with a standard cutter, the diamond table is removed from the substrate. The substrate is discarded and cobalt is removed from the diamond table. The diamond table is then attached to a new substrate. The resulting PDC cutter is deep leached, removing infiltrated cobalt to several hundred microns.
