eagle ford shale

Hi AZZérs.
Slightly off topic for AZZ and don't like discussing other stocks on another's forum but given the Eagle Ford followers in here, someone might have a good map. I'm looking at Burleson Energy's holdings in the Eagle Ford (or trying to). Anyone here have a good Eagle Ford map that shows lease all lease holders in the shale? Hold both AZZ and BUR.

Found this which is interesting read regardless...
