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 with a selectively openable and adjustable flow control valve in communication with a production tubing, located in the central wellbore between packers, and a lateral wellbore, and a selectively openable access door located adjacent the lateral wellbore allowing and preventing service tool entry into the lateral wellbore. The valve and door are individually controlled from the earth's surface.
