I suspect it's possible we've been misled (intentionally or otherwise) on the concept of renewable oil. I suspect the process IS abiotic and constant. However, I still believe that even if that's true the REAL problem is one of recovery rates and practicality. Oil that replenishes slowly and/or is extremely difficult or noncost-effective to obtain might as well be nonexistent. http://www.accesstoenergy.com/view/a...e/s76a2145.htm http://news.softpedia.com/news/Oil-P...um-85267.shtml (a little more objective than the previous article)
