You are right in this that it is most common typo, but that might be interesting IF Petroleum.org is already developed..which is not the case, it is parked page, waiting for sale with huge price tag So at the moment, no use even for redirection purposes unfortunately.what I think is that it is the most common typo for petroleum, so dont you think it can have some value may be just for redirection purpose .
For example googlr dot com redirect to google
