The FlexRite® system provides a hydraulically isolated TAML level 5 high-strength junction with sand control. This aluminum wrapped pre-milled window system incorporates a flexible junction with two semi-circular sections to maximize cross-sectional flow area and load carrying capability. The high strength of the junction allows the installation of long lateral screens for increased reservoir exposure and production capability. The FlexRite system offers through-tubing intervention and lateral re-entry with separate workover capabilities. Operations such as production logs, stimulation, clean out, water and gas isolation, water and gas shut off and can be performed on both the lower mainbore and lateral liners. The system also has the capability for an Intelligent Completion Interface.
