Harvey's rains shut in more U.S. refineries, sending fuel prices higher

HOUSTON (Reuters) - U.S. fuel prices surged on Monday as two more Gulf Coast refiners cut output and a third considered reductions, leaving more than 13 percent of the country’s refining capacity offline after Tropical Storm Harvey flooded plants and shut seaports.

The storm swung back over the Gulf of Mexico on Monday and was expected to bring another 10 to 15 inches (25 to 38 cm) of rain to the Houston area and up to 8 inches as far east as New Orleans, the National Weather Service said.

Marathon Petroleum Corp's MPC.N Galveston Bay refinery in Texas City, Texas, cut production by half, sources familiar with plant operations said.

Lyondell Basell Industries' LYB.N Houston refinery early on Monday also cut output by half to conserve crude supply, other sources said.

Meanwhile the nation’s largest plant, Motiva Enterprises’ [MOTIV.UL] 603,000-barrel-per-day (bpd) Port Arthur, Texas, refinery was considering shutting due to high water on the plant grounds and running with essential personnel only, two sources said.

The profit that refiners make per barrel of gasoline jumped as high as 21 percent RBc1-CLc1 in the first trading day following Harvey's landfall near Corpus Christi, Texas, late on Friday, as fears of short supplies gripped the market.

Gasoline for immediate delivery in the Gulf Coast hit five-year highs, traders said, while U.S. gasoline futures RBc1 jumped as much as 7 percent to $1.78 per gallon, the highest since late July 2015.
