Abstract
A method of completing a subterranean well and associated apparatus therefor provide reduced trips into the well, efficient operation, reduced costs, and increased functionality in completions where production of fluids from a lateral wellbore and a parent wellbore is desired. In one disclosed embodiment, the invention permits simultaneous conveying into the well of multiple tubing strings, the tubing strings being automatically directed to their respective wellbores. A selective deflection member is capable of selecting an appropriate tubing string and deflecting it into a lateral wellbore, while permitting another tubing string to pass axially therethrough to a lower parent wellbore.
