The US will become a net oil exporter late this year as domestic crude production surpasses imports for the first time in 18 years, the Energy Information Administration said Wednesday.
Helped by a surge in shale-based output in North Dakota and Texas, monthly crude production has pushed past seven million barrels a day and could reach eight million barrels a day by the beginning of 2014.
Imports meanwhile have dropped below eight million barrels a day and should fall below domestic ouput by the end of 2013, the EIA said.
The EIA said that based on current projections, by the end of 2014 the US could be producing two million barrels a day more than it imports, a huge turnaround in the country that, until China passed it just recently, was the world's largest oil importer.
The "unconventional" recovery of oil from dense rock strata like shale has driven a leap in domestic production in the past three years.
Average production rose from 5.5 million barrels a day for the full year 2010 to 6.5 million last year and is projected to average 7.3 million this year.
Imports meanwhile have fallen from 9.2 million barrels in 2010 to a forecast average of 7.6 million for this year.
Meanwhile Andarko Petroleum announced Tuesday that it had made a major discovery in deepwater Gulf of Mexico with its Shenandoah-2 well.
The company did not make an estimate on the size of the reserves in the new field, but said it has "the potential to become one of the most prolific new areas in the deepwater Gulf of Mexico."
