Case Study
Kymera hybrid drill bit improves steerability and increases ROP 41%
Jun 23, 2020
Overview
Challenges
- High unconfined compressive strength
- Interbedded formation
- High dog leg severity
- Inconsistent build rates
Results
- Increased ROP by 41%
- Maintained steerability
Case study details
A customer drilling the Montney formation required large dog legs of 14° and was experiencing poor toolface control resulting in inconsistent build rates when drilling with competitor polycrystalline diamond compact (PDC) bits. The Baker Hughes Drill Bit team in Canada recommended a KymeraTM hybrid drill bit to reduce the drilling dysfunctions and achieve a consistent build rate through a section consisting of siltstone, shale and fine-grained sandstone. Although this early generation Kymera drill bit demonstrated improved toolface control, the Baker Hughes team was confident that additional performance gains were achievable with an optimized design.
