19. A method of producing a well having a vertical, build and horizontal sections, and comprising a production tubing and a lining, casing or reservoir face defining an annulus, the method comprising:
a. landing a primary artificial lift system with a fluid flow management system in the build section or a heel portion of the horizontal section, the fluid flow management system including a down-hole inlet, a separator uphole of the inlet and operative to calm annular mixed phase flow and provide retention time to encourage liquid dropout to a lower section of the annulus, and a rotatable gravity-directed inlet extension arranged between the inlet and the separator and oriented in the lower section of the annulus, wherein the inlet extension is connected to an intake for the primary artificial lift system; and
b. operating the primary artificial lift system to lift fluids through the inlet extension.
