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 as much as 0.5 percent to $114.05 in trading today.
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.
The West African nations of Nigeria, Angola, Gabon and Equatorial Guinea accounted for 58 percent of the light, sweet crude imported into Gulf Coast ports in June 2012. North African nations accounted for a further 30 percent.
LLS will become about $5 a barrel cheaper than Brent during the next 12 months, David Pursell, a Houston-based managing director for Tudor, Pickering, Holt & Co., said in a telephone interview. The discount would take into account the extra cost of getting LLS to other customers, such as refiners on the East Coast, Pursell said.
Like oil in the Midcontinent, the relationship between LLS and Brent has been upended by surging shale production. West Texas Intermediate oil at Cushing, Oklahoma, the U.S. benchmark grade traded on the New York Mercantile Exchange, shifted to a discount to Brent almost two years ago after trading at a premium for decades.
Cushing inventories surged to 47.8 million barrels in June, the highest level since Energy Department records for the hub began in 2004. The WTI-Brent spread reached a record $27.88 in October. It was at $18.03 a barrel today.
“Over the last year and a half, with the WTI-Brent spread blowing out, the primary beneficiaries have been the Midcontinent players,” Cory Garcia, a Houston-based oil analyst for Raymond James & Associates, an arm of the financial-services company with almost $40 billion under management, said in a phone interview. “As LLS disconnects next year, the benefits to Gulf Coast refiners will be brought to the forefront.”
Enbridge Inc. (ENB) and Enterprise Products Partners LP (EPD) reversed the flow of crude on the Seaway pipeline on May 19. The link, carrying as much as 150,000 barrels a day from Cushing to Gulf Coast refineries, is scheduled to pump as much as 400,000 barrels a day early next year.

Anadarko Petroleum Corporation today announced the results of its first flow test offshore Mozambique. The Barquentine-2 well flowed at an equipment-constrained rate of 90 to 100 million cubic feet per day (MMcf/d), with minimal pressure drawdown, providing confidence in well designs that are capable of 100 to 200 MMcf/d.
“The test at Barquentine-2 exhibited exceptional flow characteristics, confirmed the deliverability of this reservoir and indicated a low density of development wells may be sufficient to produce the reservoir,” Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels said. “Using pre-set gauges in an offset well, we were able to confirm connectivity and reservoir continuity over a distance of more than 3 kilometers. The test also proves the reservoir has very high permeability, meeting the quality specifications for the partnership’s LNG development plans. This is a very encouraging way to start our testing program, which is an important component in the reserve certification process, as we focus on achieving FID (final investment decision) around the end of 2013.”
The Barquentine-2 well is located in water depths of approximately 5,400 feet (1,650 meters) in the Offshore Area 1 of the Rovuma Basin. The drillstem test was conducted by the Deepwater Millennium drillship, which is expected to be mobilized to the Barquentine-1 location for a second flow and interference test in the complex. The 2012 testing program also includes drillstem tests in the Lagosta and Camarao areas to the south of Barquentine.
Anadarko is the operator of the 2.6-million-acre Offshore Area 1 with a 36.5-percent working interest. Co-owners in the area are Mitsui E&P Mozambique Area 1, Limited (20 percent), BPRL Ventures Mozambique B.V. (10 percent), Videocon Mozambique Rovuma 1 Limited (10 percent) and Cove Energy Mozambique Rovuma Offshore, Ltd. (8.5 percent). Empresa Nacional de Hidrocarbonetos, E.P.’s 15-percent interest is carried through the exploration phase.
