Gulf Oil Premium at Seven-Month Low as Brent-WTI Spread Narrows

April 8 (Bloomberg) -- Light Louisiana Sweet on the spot market weakened to its smallest premium over the U.S. benchmark in more than seven months as the Brent-West Texas Intermediate differential narrowed.

Mars Blend, a medium sour Gulf crude, shrank by $1.65 to $8.85 a barrel over than WTI, the smallest premium since July 2. Crude from the Poseidon and Thunder Horse fields also weakened by $1.65 a barrel. Poseidon traded at $8.65 a barrel more than WTI, and Thunder Horse’s premium was $11.60.
