The internet is an amazing thing. I just stumbled across this today and spent an hour playing with it.
http://maps.kgs.ku.edu/oilgas/index.cfmShows every oil/gas/water well in KS. I can look at my grand parents old farm and see they have 3 water wells, 2 completed in 1976 under my GPA's name and 1 in 2007 under my uncles name(GPA passed away in 2004).
I can also see that the plot of land my dad is inheriting (GMA passed away in march
) is next to some land where there is an oil well that was completed in 2012. You can click the well and see who owns it(Long lost cousins apparently), how much it has produced every month etc etc. You can even see the core samples from the drilling in PDF's, just crazy stuff.
