Exxon borrows crude from US emergency stock amid Mars crude issue

U.S. Department of Energy announced on Friday that it will provide up to one million barrels of crude from the government’s emergency reserve at Exxon Mobil’s Baton Rouge refinery, Louisiana. The Department cited a disruption in offshore supplies.

In recent days, a zinc contamination in the Mars crude stream was detected. This has resulted in a tightening of crude supplies along the U.S. Gulf Coast. Exxon informed its trading partners that it would not purchase the Mars crude grade until the issue of zinc contamination is resolved, according to a report on Thursday.

Two sources with knowledge of the situation said that the oil major requested barrels from the Strategic Petroleum Reserve when zinc contamination in Mars crude was discovered. Mars is a medium-sour crude that's produced off the coast Louisiana. It is highly preferred by refineries on the Gulf Coast because of its properties and close proximity.

Refiners are usually configured to run specific grades of oil in order to get the best yields for different types of fuels. Switching crude grades can limit production and shrink margins.

The DOE stated that the oil exchange was approved to maintain a stable regional supply of fuels for transportation in Louisiana and along the Gulf Coast. It added that the exchange would not affect or delay efforts by the DOE to replenish the reserve.

The department said that Exxon would return the crude oil borrowed along with additional barrels for the SPR without cost to taxpayers. Exxon refused to provide further details. The supply of heavy and medium crude oil in the U.S. Gulf has tightened over recent months after Washington terminated in May a group licenses which authorized oil company PDVSA partners to transport Venezuelan crude for U.S. or European refineries.

The decline in oil production has also affected Mexico.
