In its drilling productivity report for this month, the U.S. Energy Information Administration said it expected oil production from the seven main inland shale basins to increase about 1.3 percent in December.
"The growth in production is unprecedented, exceeding all historical records, even Saudi Arabia after production from the mega Ghawar field or Soviet gas production from the super Siberian fields", Mr Birol said. "The US becomes the undisputed leader for oil and gas production for decades, which represents a major upheaval for worldwide market dynamics", said Dr Fatih Birol, IEA's executive director.
Another milestone will be reached soon after: By the late 2020s, the US - which only lifted its ban on oil exports in 2015 - will ship more oil to foreign markets than it imports.
"Yet this is precisely what is happening as a result of the USA shale revolution - both for oil and for natural gas", the IEA said.
The agency raised estimates for the amount of shale oil that can be technically recovered by about 30 per cent to 105 billion barrels.
It said the developing countries in Asia account for two-thirds of global energy growth, with the rest coming mainly from the Middle East, Africa and Latin America.
The report suggested that over the next two decades, the global energy system would be reshaped by four major forces: the United States as it becomes global oil and gas leader, rapid deployment of renewables, growing share of electricity in the energy mix, and China's new economic strategy taking it on a cleaner growth mode. The world will use just over 100 million barrels of oil a day by 2025. That "will bring a lot of dollars to USA business".
That will benefit the U.S.as it turns from imports to exports.
Increased oil production from countries not in the OPEC cartel had helped push global output higher in October, the report said.
In Abu Dhabi on Monday, the UAE Minister of Energy and Industry Suhail bin Mohammed Faraj Faris Al Mazrouei, said that oil producers were expected to unanimously extend a production cut accord later this month, but its duration was still under discussion.
"The oil market should be able to find a longer-term equilibrium, with the oil price in a range of $50-70 a barrel", the agency said.
"Even with the extraordinary move to a net export position, the health of the US energy economy remains intricately linked with those of its neighbors in North America and with choices made by countries further afield", the group said.
