Oil and gas field PDC oil bit and PDC matrix drill bit

When drilling hard, highly abrasive formations,Fixed Cutter bits will survive drilling the target interval

without sacrificing rate of penetration. fixed cutter bits drill faster and stay downhole longer in a time, a critical

advantage when rig rates continue to increase and drilling programs become more demanding.

Initially proven in the toughest formations such as the Travis Peak, Cotton Valley and Hosston, and in the

Northern Louisiana basins in the ArkLaTex region, PDC bits are now achieving superior performance in

challenging applications all over the world.

The key to achieving both bit durability and maximum ROP is maintaining drill bit stability across a broad range of

downhole conditions. bits are designed using process specifically to eliminate vibration,

resulting in maximized stability for superior wear resistance. Cutter damage is minimized, meaning drilled footage is

maximized and, since sharp cutting edges are retained longer, rate of penetration (ROP) is maintained at a higher level.

SHARC bits have the durability to eliminate unnecessary trips, thus saving time and costs for the operator. SHARC bits

are available with certification or directional certification.

In early drilling tests, a design fixed cutter bit drilled 36% more footage than a conventionally designed bit under

similar conditions. Both bits were run until their cutters reached 1-1 dull grade wear flat. At the end of the runs, the

design bit drilled 1,050 ft compared to 732 ft for the conventionally designed bit. These early results have been

substantiated by numerous real world performance comparisons documenting the ability of dynamically stablebits to out-drill the competition.

Drilling abrasive formations

Bits has developed cutters that complement the design's capability for drilling abrasive formations. The

latest technologies in materials, diamond interface design and manufacturing processes are utilized to deliver

significantly more wear resistance than cutters run in conventional applications.

Like a shark's multiple rows of teeth, cutting structure layout features two rows of cutters set on certain blades.

Each individual row reinforces the other to provide maximum durability over the critical nose and shoulder areas of the

bit, ensuring that ROP capability is not compromised.

Additionally, the bit's double rows of cutters are oriented to ensure that hydraulic cleaning and cooling efficiency are

maintained. This feature is important not only in abrasive interbedded sands but also in fast surface intervals or when

hydraulic energy is compromised, for example, on motor runs.
