Soft to Medium-Soft Formation
Application: For use in less abrasive softer formations with compressive strength ranging up to 140 Mpa, such as shales, limestones, carbonates and most metamorphic formations.
Cutting structure: These bits are characterized by large diameter, widely spaced chisel or sharp conical inserts with high projection. This configuration promotes maximum penetration rates in softer formations. Smaller carbide inserts are provided on the gage and inner rows to contain shell erosion and improve performance.
- Compression Strength: 15,000-25,000 psi
- Drilling Speeds: 80 – 110 rpm
- Jet Circulation: All sizes
- Weight on Bit (WOB): 2,000 – 5,000 lbs/in of bit diameter
IADC 5 SERIES DRILL BITS
These bits are used to drill low compressive strength, soft to medium soft formations. Drill bit design features are used to enhance bit penetration rates. Some reduction in cone offset and insert projection is used to improve cutter durability. Insert numbers and pitch is controlled to prevent tracking.
