The MillRite® junction is constructed using a track-guided milling system creating a consistent, geometrically controlled window to create a high-strength TAML level 4 junction. This construction process eliminates "rolloff" and dogleg severity problems associated with conventionally milled windows and allow repeatable lateral re-entry for the life of the well. It utilizes the successful multilateral washover operation and achieves hydraulic integrity using cement. The MillRite system can also be used to construct a TAML level 2 junction.
Applicable to existing (re-entry) and new wells
Precise window geometry
Window geometry and position control allows repeatable lateral re-entry for life of well
Compatible with IsoRite® isolated multilateral completion system and FloRite® multi-string multilateral completion system
Allows existing main well to be produced to lower economic threshold
Lower installation and maintenance costs relative to other level 4 systems
Single trip window machining
MillRite® Milled Exit Multilateral System (TAML Level 2 or 4)
The MillRite® JI system is part of the SperryRite® advanced
reservoir drainage solutions from Sperry Drilling services. It is a
combined multilateral drilling and completion system capable of
constructing a high quality junction and also providing the
required pressure isolation for selective stimulation.
