Case Study: 6-1/2" SD6541 Bit Performs Exceptionally in Liujiagou Formation

Basic Job Information

Bit Size & Model: 6-1/2" SD6541

Bit Serial Number: 3026

Well Team: 40607

Well Name: Su 25-13-13X

Formation: Liujiagou

Interval Drilled: 2880 m – 3577 m (total interval: 697 m)

Total Footage Drilled: 2183 m

Pure Drilling Time: 700 hours

Average ROP (Rate of Penetration): 3.12 m/h

Performance Highlights

The 6-1/2" SD6541 drill bit from HNS Drillbit demonstrated outstanding durability and efficiency in the Liujiagou formation of well Su 25-13-13X. Operated by well team 40607, the bit achieved a total cumulative footage of 2183 meters across multiple drilling runs, with a single continuous interval of 697 meters (from 2880 m to 3577 m).

With 700 hours of pure drilling time, the bit maintained an average rate of penetration (ROP) of 3.12 meters per hour, showcasing consistent performance and wear resistance in the challenging Liujiagou formation. This result significantly extended the bit’s service life and reduced the frequency of trip operations, directly improving drilling efficiency and lowering operational costs for the well.

Conclusion

This field case validates the superior design and reliability of HNS Drillbit’s SD6541 product line. The 6-1/2" SD6541 bit’s exceptional performance in the Liujiagou formation demonstrates its ability to deliver high ROP and long service life in demanding drilling environments, making it an ideal choice for operators seeking to optimize wellsite productivity and reduce total drilling costs.
