USGS : "Undiscovered resources are those that are estimated to exist based on geologic knowledge and theory, while technically recoverable resources are those that can be produced using currently available technology and industry practices. Whether or not it is profitable to produce these resources has not been evaluated."
This oil is theoretically in the Permian Basin. Ironically the late Permian was the time of the largest mass death on Earth. So if this undiscovered oil is "discovered," then burning it will put all that dead life back in the mix for another mass death.
