|Through the use of Wells, colonies can harness the naturally produced Energy of their new world. While Petroleum still exists, it is the new resources which ensure dry-land drilling remains an important part of human industry. When built on dry-land, Wells can provide access to much needed Geothermal and Xenomass resources.|
A Petroleum Well requires Chemistry and allows access to Petroleum resources, both on land and at sea.
