Record Setting Tangent Performance in KUWAIT


Onshore – 6” tangent section Interbedded, Limestone, Dolomite, Anhydrite and Shale formations


VION 613





Customer Challenge

The Customer focused on drilling the complete 6” holding section in deep drilling using one PDC bit run while achieving the best possible ROP and lowest cost per foot.

The previous wells in the same field used mainly PDC bit design achieving 21.5 ft/h ROP average across the field.

Record run in the area was set @ 24.2 ft/h.

Varel Solution

Utilizing Application Engineering and VAREL’s proprietary design software, the VION® PDC technology was chosen, a solution perfectly designed for “tangent” 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 steel body bit for optimum Open Face Volume. Specific cutting structure and gage configuration to provide better torque management and greater stability especially in drilling tangent section.

Purpose: Superior drilling efficiency with great compatibility with RSS Point-The-Bit directional drive system.

Customer Value
