HOUSTON, Nov 10 (Reuters) - Tropical Storm Ida shut slightly more than 43 percent of Gulf of Mexico oil production before coming ashore on Tuesday in Alabama, the U.S. Minerals Management Service said. [ID:nN10528777]

More than a quarter of U.S. offshore natural gas production was shut as Ida crossed the Gulf between Saturday and Tuesday, weakening to a tropical depression shortly after coming ashore near Mobile Bay, Alabama.

Oil and natural gas companies were quickly dispatching workers on helicopters to offshore platforms to check for damage and begin the restart process.
