A method for installing a production string in a wellbore and a production assembly for deployment in a wellbore are disclosed. An upper completion portion including a tubular and an upper circulation valve and a lower completion portion including a screen assembly and a lower circulation valve are together deployed into a wellbore at the same time. The upper circulation valve is movable between a closed position to block fluid communication between the interior and the exterior of the tubular and an open position to establish fluid communication between the interior and the exterior of the tubular. The lower circulation valve is movable between an open position to establish fluid communication between the interior and the exterior of a base pipe deployed adjacent the screen assembly and a closed position to block fluid communication between the interior and the exterior of the base pipe.
