Abstract
Provided is a downhole tool. The downhole tool, in one aspect, includes an isolation system for placement at a junction between a first wellbore and a secondary wellbore. In at least one aspect, the isolation system includes an elongated tubular, the elongated tubular having an opening connecting an interior of the elongated tubular and an exterior of the elongated tubular; and a slot located in the elongated tubular, the slot spanning the opening. In at least one aspect, the isolation system further includes an isolation sleeve located within the isolation system, the isolation sleeve configured to slide within the slot to either isolate the interior of the elongated tubular from the exterior of the elongated tubular or provide access between the interior of the elongated tubular and the exterior of the elongated tubular, and an I-shaped seal located in an annulus between the elongated tubular and the isolation sleeve.
