With a record mud weight and placement right above the liner shoe, the TrackMaster Select* system enabled a successful cased hole sidetrack in a single trip.

Results:

• Successfully completed the window in 7 inch liner in one trip.
• The window was milled and the rathole drilled in a total of 5.2 hours.
• The used tri-mill was within the acceptable gauge diameter as per criteria after the run, assuring a high-quality window.
• The subsequent directional drilling assembly passed freely through the window.
