CORRECTION:

On further reflection, the oil discovery/production in SE New Mexico is not what JB discussed years ago. The one in current news is in Texas and New Mexico, so the New Mexico field JB mentioned must have been in another part of the state, paralleling the one JB thought extended from Mexico into SE Arizona. I say that because I distinctly recall that Texas was not part of the story or even on those maps as hosting two new fields - the Permian Basis not being involved).

I don't recall who drew the maps he showed, but I think they came from a university or a major oil company. They were not his creation.
