Abstract

A wellbore sealing system is disclosed. The wellbore sealing system includes a deflection assembly positioned in a main wellbore and a junction coupled to an uphole end of the completion deflector and extending into the lateral wellbore to form a fluid and pressure tight seal. The deflection assembly includes a degradable whipstock configured to laterally deflect a drill bit such that the drill bit drills through a sidewall of the main wellbore to form a lateral wellbore, a completion deflector coupled to and located downhole from the whipstock, and an anchoring device coupled to and located downhole from the completion deflector to prevent the deflection assembly from rotating and moving in an uphole direction and a downhole direction within the main wellbore.
