US petroleum giants ExxonMobil and Chevron released blowout profits Friday, reflecting a major lift in business conditions from the Middle East war that easily offset negative effects at both companies. ExxonMobil's second-quarter profits more than doubled to $14.5 billion on surging oil prices and record refining margins due to the US-Iran war. At Chevron, profits for the three-month period were $12.1 billion, more than five times the level in the year-ago quarter. While the effects from the war mostly benefited ExxonMobil, damage to key liquefied natural gas assets in Qatar dented output. Results were also dented by reduced international refining runs because of a 10 percent drop in crude oil inputs.
