Each dot is a well on a lease the Railroad Commission lists in the Spiller field, where its map puts it, or a drilling permit filed for the field in the last 24 months. Wells of other fields are not on this map. The picture is about 11 miles across. The white counties are the ones with a well or drilling permit of the field on the map. Five more wells have no location on the state's map. The thin brown lines are the original land surveys; where there is room, a survey carries its abstract number, the number deeds and division orders cite. Sources: Railroad Commission of Texas well layers, drilling permit files and survey lines, US Census Bureau county outlines.
