Refiners Stung by Venezuela Sanctions Face U.S. Gulf Oil Exodus


Crude exports from the Gulf of Mexico are picking up at the worst time for American refiners.

Rising production and falling freight rates are behind a surge of overseas shipments of Mars crude, a medium sour oil produced in the U.S. Gulf of Mexico. This comes as sanctions on Venezuela and OPEC’s production cut agreement are limiting the availability of similar types of oil that U.S. refiners are optimized to process.
