US Patent 8695694 Borehole selector assembly

A deflector assembly includes two deflectors that can cooperate for directing a bullnose assembly toward an intended bore in a multi-bore well based on a configuration of the bullnose assembly without requiring use of gravitational forces or requiring the assembly to be oriented in a certain manner. The deflectors can cooperate by being spaced by a certain amount that, depending on if the amount is less than or greater than a longitudinal length and diameter of a bullnose of the bullnose assembly, can allow the bullnose assembly to be diverted toward the intended bore.
