110% ROP enhancement in Keshen well, Tarim field – Onshore China
Deep Vertical Well - 6000m to 7000 TVD
6-5/8” VION™ 613
VENOM™ Cutter Technology
The Customer focuses on completing the complex vertical interval comprised of extremely hard and dense formation (Sandstone & Gypsum) in Keshen well, Tarim field. The Customer objective is to achieve the best possible ROP and lowest cost per meter.
Utilizing Application Engineering and VAREL’s proprietary design software, the VION™ PDC technology was chosen, a solution perfectly designed for “vertical” applications. The VION 613 design is a trouble-free solution delivering smooth torque, advanced directional control, excellent wellbore quality and dynamic stability.
Solution: 6-bladed, 13-mm cutting structure with partial double row & single row. Specific cutting structure and gage configuration to provide better torque management and greater stability especially in drilling vertical section.
Purpose: Superior drilling efficiency with improved ROP and durability.
- Fastest 6.625” drill bit as compared to competitive offsets in the same field. 110% ROP improvement over the field average, 33% ROP improvement over the fastest offset bit and 15% improvement of cost saving per meter drilled over field average.
- 15% of cost saving translates to 153 $/m as compared to field average cost per meter
