I've been looking for it. It was on msn's front page on 9/11, i'll keep digging.

I had been looking for awhile, but I can't seem to find it. Wikipedia did say that Saudi Arabia walked out of OPEC on the 10th of September, stating that they want to keep up with the world's oil demand. They didn't want to deal with production cuts that OPEC wanted.
