Abstract

Provided, in one aspect, is a well system and a method for forming a well system. The well system, in one aspect, includes a main wellbore, the main wellbore having a main wellbore open hole section, and a lateral wellbore extending from the main wellbore, the lateral wellbore having a lateral wellbore open hole section. The well system, according to this aspect, further includes a main bore completion located within the main wellbore and a lateral bore completion located within the lateral wellbore, and a multilateral junction positioned at an intersection between the main wellbore open hole section of the main wellbore and the lateral wellbore open hole section of the lateral wellbore, the multilateral junction including a main bore leg forming a first pressure tight seal with the main bore completion and a lateral bore leg forming a second pressure tight seal with the lateral bore completion such that the main bore completion and the lateral bore completion are hydraulically isolated from one another.
