Abstract
A multi-deflector assembly for guiding a bullnose assembly into a selected borehole within a wellbore includes an upper deflector arranged within a main bore of a wellbore and defining first and second channels that extend longitudinally through the upper deflector, wherein the second channel exhibits a width greater than that of the first channel. A lower deflector is arranged within the main bore and spaced from the upper deflector by a predetermined distance. The lower deflector defines a first conduit that communicates with a lower portion of the main bore and a second conduit that communicates with a lateral bore. The upper and lower deflectors are configured to direct a bullnose assembly into one of the lateral bore and the lower portion of the main bore based on a length of a bullnose tip of the bullnose assembly as compared to the predetermined distance.
