Method for multi-lateral completion and cementing the juncture with lateral wellbores

A method for automatic selective reentry of one of a lateral wellbore and a primary wellbore comprising:

• installing an orienter in proximity to a primary/lateral junction;
• fitting a bent sub on a string being run into said primary wellbore, said bent sub having a lug in a selected location to facilitate entry to one of said lateral wellbore and said primary wellbore;
• running said string in and landing said lug on said orienter and allowing said lug to be funneled by said orienter into a slot therein whereby said bent sub is oriented to enter one of said lateral and said primary.

A system for automatically selectively reentering one of a lateral wellbore and a primary wellbore comprising:

• an orienter disposed in said primary wellbore proximate said lateral wellbore;
• a bent sub attached to a string and acting as a leading edge of said string, said bent sub having a lug selectively positioned on said sub such that upon passing said string downhole within said primary wellbore, said lug contacts said orienter, said orienter channeling said lug into a slot in said orienter whereby said bent sub is oriented to enter one of said lateral wellbore and said primary wellbore.
