BEIJING, August 26, 20l8 (News Wires) - China Petroleum & Chemical Corp. said its half-year earnings jumped to the highest level on record as refining profits climbed and a rebound in crude prices brought its oil and gas exploration unit closer to breaking even. Net income gained to 42.4 billion yuan ($6.2 billion) in the first six months from 27.9 billion a year earlier, the world's biggest refiner also known as Sinopec said in a filing to the Shanghai stock exchange on Sunday, citing international accounting standards. That's the best half-year profit on record, according to data compiled by Bloomberg dating back to 2000. Sinopec flagged the jump in first-half earnings in a profit alert last month, adding that its upstream business had "improved significantly" on higher international oil prices. The company, which makes most of its money from processing oil into fuels, has been burdened in recent years by losses from its exploration and production segment as its aging fields have higher production costs. "Good cost control and better margins from selling higher-grade fuel products helped offset higher oil purchase prices for Sinopec's refining business," said Tian Miao, a Beijing-based analyst at Everbright Sun Hung Kai Co. Sinopec shares in Hong Kong gained 1.2 per cent to close at HK$7.52 on Friday. The stock has risen 31 per cent this year compared with a 7.5 per cent decline in the city's benchmark Hang Seng Index. Global benchmark Brent crude averaged about $71 a barrel between January and June from $53 a year earlier. Operating losses from Sinopec's exploration and production division narrowed to 412 million yuan in the first half from 18.3 billion yuan a year earlier, according to the statement. Operating profit from the refining business climbed 32.5 per cent to 38.9 billion yuan, while the chemical segment posted a 29.7 per cent gain. "While higher oil prices boosted Sinopec's upstream business, it still falls short of breaking even," Tian said. "That might raise concern on how competitive its exploration business is, as even with oil prices at about $70, it's still unable to turn a profit."
