Here are the maps, the first one i have highlited AQO's leases in Black, SXY and DLS leases in purpule and Santos leases in Red. As u can see, STO's leases are all light brown which reffers to production leases.

The second map is from Santos's website showing there tenemants in Yellow and have circled the tenemants around AQO's in red in try and match Map 1 as best as possible.
