LONDON – The United States will overtake Saudi Arabia and Russia as the world's top oil producer by 2017, the West's energy agency said Monday, predicting Washington will come very close to achieving a previously unthinkable energy self-sufficiency. The forecasts by the International Energy Agency (IEA), which advises large industrialized nations on energy policy, were in sharp contrast to previous IEA reports, which saw Saudi Arabia remaining the top producer until 2035. “Energy developments in the United States are profound and their effect will be felt well beyond North America - and the energy sector,” the IEA said in its annual long-term report, giving one of the most optimistic forecasts for US energy production growth to date. “The recent rebound in US oil and gas production, driven by upstream technologies that are unlocking light tight oil and shale gas resources, is spurring economic activity - with less expensive gas and electricity prices giving industry a competitive edge,” it added. The IEA said it saw a continued fall in US oil imports with North America becoming a net oil exporter by around 2030 and the United States becoming almost self-sufficient in energy by 2035. IEA Chief Economist Fatih Birol told a news conference in London that he realized how optimistic the IEA forecasts were given that the shale oil boom was a relatively new phenomenon. “Light, tight oil resources are poorly known ... If no new resources are discovered (after 2020) and plus, if the prices are not as high as today, then we may see Saudi Arabia coming back and being the first producer again,” he said. The IEA said it saw US oil production rising to 10 million barrels per day (bpd) by 2015 and 11.1 million bpd in 2020 before slipping to 9.2 million bpd by 2035. Saudi Arabian oil output would be 10.9 million bpd by 2015, the IEA said, 10.6 million bpd in 2020 but would rise to 12.3 million bpd by 2035. A rise of 1.8 billion in the world's population to 8.6 billion would lead to a spike in global oil demand by more than a 10th to over 99 million bpd by 2035, keeping pressure on oil prices, the IEA said. The agency's central “New Policies” scenario, which assumes a range of measures are taken to curb oil consumption in Europe, the United States, China and elsewhere, sees the average import cost of oil rise to just over $215 per barrel by 2035 in nominal terms, or $125 in 2011 terms. If fewer steps are taken to promote renewable energy and curb carbon dioxide emissions, oil was likely to exceed $250 per barrel in nominal terms by 2035 and reach $145 in real terms - almost level with the record highs seen four years ago. – Reuters
