A well completion apparatus and method comprises a junction assembly having a template and a lateral branch connector engageable with the template to couple a main bore to a lateral branch bore. To improve inter-engagement characteristics of the template and connector, one arrangement of the junction assembly utilizes a continuous rail and groove inter-engagement mechanism. In another arrangement, a portion of the rail and groove inter-engagement mechanism is segmented instead of continuous. A method and apparatus is also provided in some arrangements to enable placement of intelligent completion devices in a lateral branch. Additionally, some junction assemblies comprise flow control mechanisms to control commingling, or not, of fluids from different regions in the well bore.
