Offers multiple advantages in interbedded lithology.
Enhanced bit stability with BHA shock and vibration mitigation.
FEA software for tool distribution and layout makes drilling more efficient and reduces NPT.
The tool angle is optimized axially and radially by FBS (Force Balance Analysis) software, resulting in a more
aggressive and durable drill.
Through a series of empirical calculations and optimization of DOC (depth) of the drill bit, the tool can enter the
formation more reasonably.
