1. A method comprising: logically dividing an irregular polygon into a plurality of contiguous sub-areas, the irregular polygon representing an outer boundary of mineral rights, and the logically dividing by a computer system; planning a first plurality of layouts of lateral wellbores residing in a first sub-area, each layout along a distinct azimuthal direction, the planning by the computer system; selecting a layout of the first plurality of layouts based on a selection criteria, the selecting creates a first selected layout; planning a second plurality of layouts of lateral wellbores residing in a second sub-area, each layout of the second plurality of layouts along a distinct azimuthal direction, and the planning by the computer system; selecting a layout of the second plurality of layouts based on a selection criteria, the selecting creates a second selected layout; combining the first and second selected layouts to create an overall layout for lateral wellbores within the outer boundary of mineral rights represented by the irregular polygon, the combining by the computer system; displaying the overall layout on a display device; and drilling one or more of the lateral wellbores within the outer boundary of mineral rights according to the overall layout.
