US Gulf Oil Production Cut by 63% as Hurricane Nears
Hurricane Isaias caused a 63% cut in US Gulf oil production (1.3M barrels/day) and 57% in natural gas. Prices rose 4% due to supply disruptions. BP, Chevron, ENI, Murphy, and Shell are affected. About 9M barrels could be lost, exceeding Tropical Storm Bertha's impact. 500,000 barrels/day of refining capacity is at risk.
