Abstract

An apparatus for use in a wellbore includes an outer assembly and inner assembly. The outer assembly includes a set down profile, a first flow device for supplying a fluid to a zone in the wellbore and a second flow device for providing a flow path from the formation to inside of the outer assembly. The inner assembly includes a frac port for supplying a fluid from the inner assembly to the first flow device, a valve below the frac port that remains closed when a fluid at a selected flow rate flows downward from above the valve, and a bypass device uphole of the valve. The bypass device opens when the inner assembly is set down in the set down profile and provides a flow path from below the frac port to an annulus between the inner assembly and the outer assembly above the frac port.
