WICHITA, Kansas -- Hurricane Isaac churning up gas prices in Wichita.
On Tuesday morning, the price shot up about 12 cents to $3.75.
The U.S. government says 78 percent of the oil production in the Gulf of Mexico has been halted in preparation for Isaac.
The Bureau of Safety and Environmental Enforcement reports about 1 million barrels per day of oil production has been stopped as companies have evacuated 346 offshore oil and gas production platforms.
That's 17 percent of daily U.S. oil production and 6 percent of consumption.
The agency says 2 billion cubic feet of natural gas production is also affected. That's about 3 percent of daily U.S. production and consumption.
Production is expected to quickly resume after the storm passes.
