When drilling and development plans call for a complex multilateral production scheme, or if it becomes necessary to sidetrack around obstacles downhole, the Schlumberger TrackMaster OH openhole whipstock system provides application-specific, sidetrack reliability.
Sidetracking with a cement plug means extra materials, long cure times, and often multiple setting attempts. The TrackMaster OH whipstock and sidetracking system eliminates these complications by setting a reliable, hydraulically expandable anchor so you can drill ahead in one trip.
With the system’s anchor set, the TrackMaster OH whipstock’s bit-friendly steel ramp provides a positive means of controlling the kickoff depth and orientation. This feature is especially useful when drilling medium to hard formations or landing laterals with tight TVD tolerance, when a cement plug cannot guarantee a successful sidetrack.
To meet the wide variety of sidetracking operations, TrackMaster systems can be configured for the full range of non-cementing applications whenever departure from the wellbore is required. Depending on the application, there are a single-trip and drill-ahead systems with specific drillbit options:
And, for openhole sidetrack applications requiring isolation of the original borehole with a cement plug below the kickoff point, the TrackMaster OH-C openhole whipstock and cementing system can be oriented as required.
The TrackMaster OH-C openhole whipstock and cementing system maximizes the probability of successfully sidetracking on the first attempt, with no need to wait for cement to harden. The system saved up to 24 h of rig time per well, on over 40 land wells in multiple US basins.
