NEW ORLEANS (AP) - Hurricane Harvey has prompted offshore oil and gas operators to evacuate platforms and drilling rigs in the Gulf of Mexico toward a Texas landfall.

The federal Bureau of Safety and Environmental Enforcement, which regulates offshore drilling, says in a news release that it estimates just under 10 percent of oil production in the Gulf had been stopped as of midday Thursday; and less than 1 percent of natural gas production.

The agency's New Orleans office says workers had been evacuated from 39 of the Gulf's 737 production platforms and one of approximately 30 drilling rigs.
