Kymera hybrid bit delivers benchmark ROP on J-shape wellpath in Kuwait’s Raudhatain field
May 31, 2023
Challenges
- Highly interbedded formations
- Increased risk of severe and/or total losses in the Dammam, Radhuma, Tayarat, and Sadiformations
- Challenging well design (build to 20° then hold angle to TD)
- Limited flow rates (850 gpm maximum) due to rig capacity and ECD management
- Aggressive ROP target and desire to minimize off-bottom time to reduce overall section time
Solution
- 16” Kymera™ Hybrid drill bit run on a 9 ⅝” performance bent motor assembly to drill shoe-to-shoe in a single run
- Maximized hydraulic horsepower to improve bit face cleaning and cooling vs. previous runs
- Optimized drilling parameters to ensure maximum instantaneous ROP
- Increased differential pressure (25% greater in both sliding and rotary modes vs. offset runs)
