Abstract
A deflector assembly includes an upper deflector arranged within a main bore of a wellbore, the upper deflector having first and second plates spaced apart by a distance. At least one of the first and second plates includes a ramped surface. A lower deflector is arranged within the main bore, the lower deflector defining a first conduit and a second conduit. One of the first and second conduits is in communication with a lower portion of the main bore and another of the first and second conduits is in communication with a lateral bore. The upper and lower deflectors are configured to direct a bullnose assembly into either the lateral bore or the lower portion of the main bore based on a size of a bullnose tip of the bullnose assembly.
