1. A computer implemented method of formulating well completions of at least one multilateral well in a subsurface reservoir producing hydrocarbon fluids, the reservoir being organized as a reservoir model partitioned into a number of cells, the computer implemented method comprising the steps of:
performing a reservoir simulation to determine hydrocarbon fluid content of the cells in reservoir model;
forming a measure of expected cumulative production for the cells based on productivity of the determined hydrocarbon fluid content of the cells;
generating a model for the at least one multilateral well by transshipment network analysis of the measures of expected cumulative production to maximize produced hydrocarbons for the cells;
optimizing placement of the generated model of the at least one multilateral well in the reservoir model; and
forming an output display of the at least one multilateral well at a location in the reservoir model according to the step of optimizing placement; and
placing the at least one multilateral well in the subsurface reservoir according to the location in the reservoir model formed in the output display.
