Abstract
A wellbore isolation system is disclosed. The wellbore isolation system includes a junction positioned at an intersection of a first wellbore and a second wellbore, and a deflector disposed in the junction such that a path into the first leg of the junction is obstructed and engaged with the first leg of the junction to form a fluid and pressure tight seal. The junction includes a first leg extending downhole into the first wellbore, and a second leg extending downhole into the second wellbore. The deflector includes a channel extending axially through the deflector, and a degradable plug disposed in the channel and engaged with the channel to prevent fluid flow through the channel.
