TrackMaster Select

Modular whipstock sidetracking system

The TrackMaster Select system is a modular tool configuration adaptable for applications from single or multiple casing exits and openhole sidetracking to offshore extended windows and multilateral

TrackMaster Select system anchor options.
The TrackMaster Select system has five types of anchors (left to right): hydraulically actuated expandable anchor, retrievable anchor, retrievable anchor with packer assembly, permanent packer anchor, and mechanical anchor.
TrackMaster Select system exits three casings.
The TrackMaster Select system’s premium mills enable quality window exits in high-grade steel and chrome casings and in formations with unconfined compressive strengths of more than 40,000 psi [276 MPa].

Reducing sidetracking time and increasing system reliability

The system features a single-piece mill with integral blades and a newly designed cutting structure with brazed cylindrical cutters. The forged body eliminates the welding process and the resulting heat effect, producing a much stronger mill with improved fatigue life. We used the IDEAS integrated dynamic design and analysis platform to design the cutting structure, which incorporates superior cutters to make milling faster than ever. The whipstock retrievability has also been improved as the hook slot location is optimized and the new mill design can preserve the thickness at the top of the whipstock, providing a more reliable sidetracking system.

Digitally enabled for better planning and higher performance

Unique to the TrackMaster Select system is the ability to design an optimal BHA, model window geometry, and perform following string pass-through and milling simulations, as well as bending stress and downhole dynamics analysis. It enables better performance right from the planning stage and is supported by the DrillPlan digital well construction planning solution. Overall well planning is improved to ensure high performance and that the exit window expedites passage of the BHA.

WhipSim whipstock simulation software can be utilized as part of the prejob planning to generate 2D and 3D visualizations of the sidetracking operation before drilling takes place prior to the actual job.
