Abstract
A method and apparatus for selectively producing fluids from multiple lateral wellbores that extend from a central wellbore. The apparatus comprises a fluid flow assembly (24) with a selectively openable and adjustable flow control valve in communication with a production tubing (20), located in the central wellbore (10) between packers (32), and a lateral wellbore (12), and a selectively operable access door (30) located adjacent the lateral wellbore (12) allowing and preventing service tool entry into the lateral wellbore. The valve and door (30) are individually controlled from the earth's surface.
