For quick reference, here are several maps associated with shale gas, in the US and in North Carolina.

The Cumnock Formation, shown here grouped with the Sanford and Penick Formations, has the highest potential for natural gas in NC given its chemistry and thickness. Data courtesy of NC One Map.
The Southern Environmental Law Center has a broader map on their website of public water supply systems, both groundwater sourced and surface water sourced, in context of the Triassic Basins in NC (there is a second map of the southeast US displaying the Triassic Basins and National Forests).
To learn whether you own the mineral rights on your property, contact your county’s Register of Deeds. Here are the links to contact information and access to searchable databases for these NC counties’ Register of Deeds:
The Lee County GIS/Strategic Planning Department has a searchable GIS map online with a layer of properties that have signed mineral leases.
A geological cross-section of the Sanford sub-basin with the Cumnock Formation clearly marked (and also the Dan River Basin), courtesy of NCGS. Those of you not familiar with a geological cross-section, imagine cutting into a two-layer cake, and after removing that piece looking into the cake and seeing the icing, the cake, the middle icing, and more cake – and that is the simplistic explanation of what we see in a geological cross-section.
