The U.S. shale boom has driven the cost of Gulf Coast light, sweet oil to its lowest level versus Brent crude in almost a quarter century as the nation’s dependence on foreign supplies wanes.
Light Louisiana Sweet, the benchmark grade for the Gulf Coast known as LLS, has traded on the spot market at an average of 15 cents a barrel more than Brent this year, the smallest premium since at least 1988, data compiled by Bloomberg show. The spread’s highest annual average was $4.02 in 2008.
The drop has cut costs for refiners in Texas and Louisiana accounting for 45 percent of U.S. capacity and replaced competing shipments from Africa. Gulf imports of light, sweet crude have fallen 56 percent since 2010, according to U.S. Energy Department data. A shale-oil influx from the Eagle Ford formation in Texas and Bakken in North Dakota and new ways to bring crude to the Gulf, such as this year’s reversal of the Seaway pipeline, may accelerate the shift.
“The market dynamics are changing,” Edward L. Morse, head of commodities research at Citigroup Global Markets in New York, said in a telephone interview. “When the Gulf Coast was a crude importer, they had to attract crude from elsewhere in the world, which meant LLS had to be at a premium to Brent. But now we’re moving into a totally different situation.”
Light Louisiana Sweet, a grade prized because its low-sulfur content and density make it easier to process into fuels such as gasoline, was 92 cents cheaper than Brent yesterday. It averaged 20 cents less than the benchmark in the third quarter.
Brent oil for October settlement rose 40 cents, or 0.4 percent, to $113.49 a barrel yesterday on the London-based ICE Futures Europe exchange. The contract advanced 89 cents, or 0.8 percent, to $114.38 a barrel at 8:42 a.m. in New York.
U.S. oil output surged to the highest level in 13 years in July, according to weekly Energy Department data. The U.S. met 83 percent of its energy demand from domestic sources in the first five months of this year and is heading for the highest annual level since 1991, department figures compiled by Bloomberg show.
“Unconventional oils and gas are changing everything about our competitiveness in the United States,” Bill Klesse, Valero Energy Corp.’s chief executive officer, said yesterday at the Barclays CEO Energy/Power Conference in New York. “Before you know it, we’re going to have so much light, sweet crude that in the U.S. Gulf Coast we’re not going to be importing light, sweet crude, and we think that happens next year.”
Houston, New Orleans and other ports along the Gulf Coast accepted about 554,000 barrels a day of light, sweet oil from outside the U.S. in June, down from 964,000 barrels a day in June 2011 and about 1.25 million in June 2010, according to the Energy Department’s Energy Information Administration.
