An Advanced Open Hole Sidetrack Application Saves 800ft of Drilled Interval in a Middle East Well

A TrackMaster* OH system was successfully deployed across another previously set whipstock and through several washout areas to complete an unplanned sidetrack objective.


  • The 8 3/8 in. open hole sidetrack was completed in one trip and saved 800ft of previously drilled interval.
  • The sidetrack was completed in a total of 6 hours.
  • The used bi-mill was within the acceptable gauge diameter as per criteria after the run, assuring a high-quality sidetrack.
  • The subsequent directional RSS BHA passed freely through the window to continue drilling and meet the customers’ objectives.
