Five years ago, many oil experts saw trouble looming. In 10 years or so, they said, oil producers outside the Organization of the Petroleum Exporting Countries (OPEC) would likely be unable to pump oil any faster and OPEC would gain an even stronger hand among the world's oil producers. Five years on, it appears those experts may have been unduly optimistic—non-OPEC oil production may have been peaking as they spoke. Despite a near tripling of world oil prices, non-OPEC production, which accounts for 60% of world output, hasn't increased significantly since 2004. And many of those same experts, as well as some major oil companies, don't see it increasing again—ever. Optimists remain. Some experts still see production from new frontiers, such as Kazakhstan, the deep waters off Brazil, and the oil sands of Canada, pushing production above the current plateau in the next few years. But time's running out to prove that newly discovered fields and new technology can more than compensate for flagging production from the rapidly aging fields beyond OPEC.
