Natural Gas Well Coal Topologies

These are upper and lower coal topologies, well sites, and fault movement maps I created for a rather large gas field as part of a geology contract. I scanned and overlayed county, topology, and gas field maps to make the base map, then filled in the data. All this was done in AutoCAD Map 5, and some of the final drawings where imported into Adobe Illustrator which makes nicer PDFs for the lawyers.
