New PDC Benchmark Sets in OMAN
Onshore – 16” vertical section Interbedded, Limestone and Shale surface sediments formations
HYDRA CURVE NOZZLES FEATURE
The Customer focused on drilling the complete 16” section in one PDC bit run while achieving the best possible ROP and lowest cost per foot.
The previous wells used mainly PDC bit design achieving 31.7 m/h ROP average across the field.
Record run in the area was set @ 66.1 m/h.
VAREL proposed a specific PDC design leveraging the RAIDER platform with part of HYDRATM technology. Design optimization using our PDC Designer and DIG-IT 3DTM software for optimal simulation and CFD analysis was performed for superior Hydraulics design.
Solution: 6-bladed, 19-mm aggressive cutting structure with steel body bit to maximize open face volume and junk slot area. Curve nozzle features were utilized.
Purpose: Superior drilling efficiency and cutting removals from the cutter / rock interface to allow optimal cleaning and cooling together with sharpness preservation of the PDC.
New consistent field record achieved and time saving on the planned objective.
- ROP Field record run with 89.5 m/h
- Achieved 35.4% increase in ROP as compared to previous run record performance.
- Achieved 182.3% increase in ROP as compared to field / application average.
