Abstract
Planning lateral wellbores within irregular boundaries. At least some of the illustrative embodiments are methods including: logically dividing an irregular polygon into a plurality of contiguous sub-areas, the irregular polygon representing an outer boundary of mineral rights; planning a first plurality of layouts of lateral wellbores residing in a first sub-area, each layout along a distinct azimuthal direction; 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; selecting a layout of the second plurality of layouts based on a selection criteria, the selecting creates a second selected layout; creating an overall layout for the irregular polygon by combining the first and second selected layouts; and displaying the overall layout on a display device.
