Each dot is a well on a lease the Railroad Commission lists in the Calliham 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 6 miles across. The white counties are the ones with a well or drilling permit of the field on the 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.
