Yes, Paul Roberts' The End of Oil was what got me interested in the subject. I literally picked it off the bookshelf, read the introduction and was transfixed. He explained it all quite well.
I read a PO book written by an oil geologist and liked it, complete with the decently explained technicalness. I'll have to dig it up to get the title. It included some oil geology humor. I think it was "The End of Oil" but not sure.
