Abstract
A wellbore system includes an upper deflector arranged within a main bore and defines first and second channels that extend longitudinally therethrough. 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. A bullnose assembly includes a body, a bullnose tip arranged at a distal end of the body, and a sleeve member arranged about the body. The sleeve member or the bullnose tip is axially movable to vary a length of the bullnose tip, and the upper and lower deflectors direct the bullnose assembly into the lateral bore or the lower portion of the main bore based on the length of the bullnose tip.
