Gas prices rise as Isaac throttles the Gulf
Gas prices are expected to jump 10 cents Monday to $3.008 per gallon. The rise in gas prices comes as Tropical Storm Isaac churns its way through the Gulf of Mexico.
Oil prices rose Monday as Tropical Storm Isaac barreled across the Gulf of Mexico and toward the U.S. mainland, picking up strength and threatening oil and refining operations. An explosion at a refinery in Venezuela also pushed prices higher.
Benchmark crude for October delivery rose $1.03 in late afternoon Bangkok time to $97.18 per barrel in electronic trading on the New York Mercantile Exchange. The contract fell 12 cents to finish at $96.15 per barrel on the Nymex on Friday.
Brent crude rose $1.21 to $114.80 on the ICE Futures exchange in London.
Oil analyst Stephen Schork said in an email commentary that he expects "much higher volatility this week" due to Tropical Storm Isaac, which weather forecasters said would pick up strength before striking as a Category 2 hurricane somewhere between New Orleans and the Florida Panhandle on Wednesday.
Schork worries that the storm will be a repeat of Hurricanes Katrina in 2005 and Gustav in 208, damaging Gulf refineries and pipelines and disrupting oil tanker traffic.
Another factor pushing up prices was an explosion and fire that shut down operations at the Amuay refinery in western Venezuela, said Victor Shum, energy analyst at consultancy Purvin & Gertz in Singapore.
Amuay is among the world's largest refineries and is part of the Paraguana Refinery Complex, which also includes the adjacent Cardon refinery. Together, the refineries process about 900,000 barrels of crude per day and 200,000 barrels of gasoline.
Gasoline futures rose nearly 10 cents to $3.008 per gallon. Heating oil rose 5 cents to $3.1727 per gallon. Natural gas rose 4 cents to $2.743 per 1,000 cubic feet.
