Abstract
A main borehole is drilled into an underground reservoir comprising a plurality of layers of different fluid mobilities. The fluid mobility in each of the plurality of layers is determined. A number of lateral boreholes extending from the main borehole in each of the plurality of layers are then drilled based on the determined fluid mobility in each of the plurality of layers, such that resulting fluid production rates in each of the plurality of layers are substantially similar.
