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. Whether performing a cased-hole sidetrack through a milled window or an openhole sidetrack using a whipstock, the ST series provides the cutting aggression and directional control required for successful sidetrack operations.

Sidetrack Geometry
Specialized bit profile with tapered gauge and aggressive face cutters facilitates clean departure from the original wellbore path through formation or casing exit.
Window Milling Capable
Reinforced cutting structure can drill through cement and engage formation immediately after passing through a casing exit window.
Directional Control
Controlled gauge aggressiveness and balanced cutting forces provide predictable steering response when used with motor or RSS assemblies.
Formation Versatility
Effective across a wide range of formation types, from the soft cement of the sidetrack window to the harder formations of the new wellbore trajectory.

Cased Hole Sidetrack
Drills through milled casing windows and establishes new wellbore sections for accessing bypassed reserves or avoiding damaged zones.
Openhole Sidetrack
Initiates new wellbore trajectories from openhole sections using whipstock or motor-based deviation techniques.
Re-Entry Drilling
Efficient re-entry through existing wells to extend producing zones or create new lateral access to untapped reservoir sections.
Well Abandonment Support
Creates controlled sidetracks for well abandonment programs requiring cement plugs at specific locations along new wellbore paths.

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, whether through a milled casing window or from an openhole kickoff point. The face cutting structure is designed to transition smoothly from the softer cement of the window area to the native formation, 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, casing program, and expected formation properties. We stock the most popular ST sizes at our Dubai warehouse for rapid mobilization. Contact us to discuss your upcoming sidetrack project and discover how the ST series can contribute to its success.
