Disclosed are methods of deflecting expandable bullnose assemblies. One method includes introducing a bullnose assembly into a main bore of a wellbore, the bullnose assembly including a body and a bullnose tip arranged at a distal end of the body and being configured to move between a default configuration, where the bullnose tip exhibits a first diameter, and an actuated configuration, where the bullnose tip exhibits a second diameter different than the first diameter, advancing the bullnose assembly to a deflector arranged within the main bore and defining a first channel that exhibits a predetermined diameter and communicates with a lower portion of the main bore, and a second channel that communicates with a lateral bore, and directing the bullnose assembly into either the lower portion of the main bore or the lateral bore based on a diameter of the bullnose tip as compared to the predetermined diameter. |
