SideTrack (ST) PDC Bits
Specialized Geometry for Sidetracking Operations
The SideTrack (ST) series features specialized cutting profiles and bit geometry engineered for initiating and drilling new wellbore sections from existing wells. Designed for open-hole sidetracking, the ST series provides the cutting aggression and directional control required for successful sidetrack operations with fast execution. SideTrack (ST) bits are made to order; the lead time is confirmed with each quotation.

Sidetrack Geometry
Specialized bit profile with tapered gauge and aggressive face cutters facilitates clean departure from the original wellbore path in open hole.
Open-Hole Sidetracking
Designed for open-hole sidetracking with 6 blades and 13 mm cutters or 9 blades and 10 mm cutters, delivering high performance and fast execution of the operation.
Directional Control
Controlled gauge aggressiveness and balanced cutting forces provide predictable steering response when used with motor or RSS assemblies.
Formation Focus
Designed for medium formations with hard interlayers (MH) encountered along the new wellbore trajectory.

SideTrack (ST): Precision Bits for New Wellbore Creation
Sidetracking is one of the most valuable techniques in modern well construction, enabling operators to access bypassed pay zones, avoid damaged wellbore sections, or create entirely new production intervals from existing wells. The SideTrack (ST) PDC bit series from VBM is purpose-engineered for these demanding operations, providing the cutting geometry and directional characteristics required for successful sidetrack execution.
The ST bit features a specialized profile that differs fundamentally from conventional drilling PDC bits. The tapered gauge design and pilot nose geometry facilitate a clean departure from the original wellbore from an open-hole kickoff point. The face cutting structure is designed to engage the native formation smoothly, maintaining directional control throughout the critical initial phase of the sidetrack.
Directional predictability is essential during sidetrack operations, where the bit must follow a precisely planned trajectory from the moment it exits the original wellbore. The ST cutting structure is balanced to provide controlled side-cutting capability with minimal tendency for bit walk or unpredictable deviation. This makes the ST an ideal choice for use with mud motors, rotary steerable systems, and whipstock assemblies commonly employed in sidetrack operations.
VBM Middle East has extensive experience supporting sidetrack operations across the Gulf region. Our team can recommend the optimal ST configuration based on your sidetrack plan, well design, and expected formation properties. ST bits are available on order and manufactured to your specification, with lead time confirmed on request.
