Application-specific PDC bits engineered for special or extreme conditions—highly abra sive sandstones, faulted/fractured zones, interbedded foramtions, water-bearing/sandy layers, long runs, low circulation, unstable/ collapsible holes, and directional gas-drainage wells. We tailor bit geometry, blade & hydraulics, gauge protection, anti-balling and an ti-collapse features to maximize ROP, tool life, and hole quality.
