Applications
- Complex and abrasive strata (chert)
- Long well lengths where POOH is costly and counterproductive
- Precise control desired in complex subsurface environment
- High temperature environments where cutter must withstand extreme conditions without compromising performance
Features and Benefits
- Proprietary blend of diamond mesh that increase diamond particle retention.
- Proven field experience with comparatively superior ROP
- Equating to fewer trip outs and short drilling times.
- Coarse center diamond to increase ROP
- High wear resistance resulting in high ROP
Specifications
- Field proven 13.5mm ODx18mm OL and 15.875mm ODx8mm OL. Additional sizes available upon request.
- Matrix hardness of 60 HRC
Field Trials
- Field deployment in Longtan Formation, China.
- Lithology: limestone, shale
- Drilling time was 28.35 hrs over 429 m, resulting in 15.13 m/h ROP.
- Average competitor ROP 6.83 – 9.55 m/h.
- Intact blades, no mud pack, unblocked water holes
- Drill bit freshness 70%
