The ringed dot is this lease's well, where the Railroad Commission's map puts it. The other dots are wells and drilling permits of the last 24 months on the land around it; the counts are for everything in the picture, which is about 6 miles across. 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.
