* Output of light, tight oil to surge in next decade-IEA
* IEA slightly raises long-term oil demand forecast, price view
* India, not China, to lead global demand growth after 2020 (Changes “by 2016” to “in 2015” in para 1 after IEA news conference, adds details))

LONDON, Nov 12 (Reuters) - The United States will stride past Saudi Arabia and Russia to become the world’s top oil producer in 2015, the West’s energy agency said, bringing Washington closer to energy self-sufficiency and reducing the need for OPEC supply.
But by 2020, the oilfields of Texas and North Dakota will be past their prime and the Middle East will regain its dominance - especially as a supplier to Asia, the International Energy Agency (IEA) said on Tuesday.
A boom in shale oil in the United States has reversed a decline in its oil output and the IEA, adviser to industrialised nations, predicted in its 2012 World Energy Outlook the U.S. would surpass Riyadh as top producer in 2017.
Introducing this year’s outlook at a news conference in London on Tuesday, IEA Chief Economist Fatih Birol said the agency now expects the re-ordering earlier.
“We expect in 2015 the U.S. to be the largest oil producer in the world,” he said.
“We see two chapters in the oil markets,” he told Reuters in an interview. “Up to 2020, we expect the light, tight oil to increase - I would call it a surge. And due to the increase coming from Brazil, the need for Middle East oil in the next few years will definitely be less.”
“But due to the limited resource base (of U.S. tight oil), it is going to plateau and decline. After 2020 there will be a major dominance of Middle East oil.”
Oil prices would continue to rise, the IEA said, and spur development of unconventional resources such as the light, tight oil that has fueled the U.S. oil boom, oil sands in Canada, deepwater production in Brazil and natural gas liquids.
The average crude import price of IEA members will climb steadily to $128 a barrel in 2012 terms by 2035 - up $3 from 2012’s outlook. The nominal price by 2035 will be $216, similar to last year’s assumption.
Other nations are unlikely to match the success of the United States in tapping shale, the IEA said.
While tight oil output is set to soar in the next few years, the Paris-based agency said the world was not “on the cusp of a new era of oil abundance” and repeated that investment in new supply needed to be kept up to avert any future supply crunch.
By the mid-2020s, non-OPEC production will fall back and countries in the Middle East - home to core members of the Organization of the Petroleum Exporting Countries - will provide most of the increase in global supply.
Birol said it was essential that investments continue to be made in the plentiful, low-cost resources of the Middle East in order to meet growing demand from Asia.
“The Middle East is and will remain the heart of the global oil industry for many years to come,” he told Reuters.
“Giving the wrong signal to Middle East producers may well delay investment. If we want Middle East oil in 2020, the investments need to be made by now.”
Rising U.S. tight oil production is for now helping to meet growing demand, which the IEA forecasts will reach 101 million barrels per day (bpd) in 2035, up from 86.7 million bpd in 2011 and up slightly from 99.7 million bpd expected last year.
“Shale oil is very good news for the United States and for the world. But the demand is in Asia,” Birol said.
“First China, and then after 2020 driven by India. Therefore we need Middle East oil for the Asian demand growth.”
China is due to overtake the United States as the largest oil-consuming country and Middle East oil consumption is expected to surpass that of the European Union, both around 2030, the IEA said.
India is forecast to become the largest single source of global oil demand growth after 2020.
The share of the United States in global energy-intensive industries - chemicals, aluminium, cement, iron, steel, paper, glass and oil refining - will increase slightly thanks to cheaper energy. By contrast, the EU and Japan will lose one third of their current share.
The IEA also said that up to 10 million bpd of global oil refining capacity was at risk as global refining centres were relocating closer to Asia. (Editing by Dale Hudson, Ron Askew)
