1 -

Set template and selective landing tool in ICC or on a packer below milled window after running lower completion equipment. Position template opening across casing-exit window. Retrieve template running tools.
2 - Insert connector downhole until the lower end engages in the polished-bore receptacle (PBR) on top of dropoff liner and the upper end lands in the template. Retrieve running tools.
3 - Complete junction installations.

4 -

Set tubing and packer for upper lateral. Tie into template PBR if hydraulic isolation is required at the junction.
5 - Set a selective through-tubing access (STTA) device with a locking profile and a deflector in the template to divert tools into the lateral for remedial interventions.
6 - Install an internal sleeve to isolate a lateral from the main wellbore.

Junction Connectivity, Stability, Strength and Sand Exclusion
RapidConnect and RapidExclude systems consist of two main components that are assembled downhole to close dimensional tolerances, not prefabricated, to yield high-strength junctions. The first component, a template with precut window and guide rails, is set across a window milled in the primary casing using the RapidAccess system. The second component, a connector, physically anchors lateral liners to the template.

Continuous engagement between the template guide rail and connector profile provides better load support and mechanical junction integrity in the event of formation instability or movement. The modified RapidExclude template profile also excludes formation grains in unconsolidated or weakly consolidated reservoirs.

If unplanned laterals are required in a wellbore where there is no ICC, RapidConnect and RapidExclude systems can be installed using a conventional retrievable packer as the reference datum and construction platform.

RapidConnect and RapidExclude junction systems have two main components, a template and a connector. An ICC orients the precut template window adjacent to a milled casing-exit window. Connector profiles at the top of a liner and template guide rails interlock to create a strong, durable connection.
