FACTBOX-Gulf of Mexico energy ops recovering from Ida

(Updates throughout)

Nov 10 (Reuters) - Tropical Storm Ida had been downgraded
to a tropical depression by the time it came ashore at Dauphin
Island, Alabama, near Mobile, on Tuesday at 5:40 a.m. CST (1140
GMT) and the National Hurricane Center reduced it to
'extratropical' status as its remnants crossed Florida, Alabama
and Georgia later Tuesday. Energy experts predicted that oil
industry operations that had been shut down ahead of the storm
would return to normal by the end of Tuesday or early
Wednesday.

Energy companies had shut 43.09 percent of oil production
and 27.96 percent of natural gas output in the Gulf of Mexico
Tuesday as the storm spun ashore. At its peak crossing the
Gulf, Ida had been a late-season Category 2 hurricane.

The Gulf is the source of 25 percent of U.S. domestically
produced oil and 15 percent of natural gas. About 40 percent of
U.S. refining capacity is located on the Gulf Coast.

Oil and natural gas futures prices were falling Tuesday
after spiking on storm risks Monday. Crude oil futures on the
New York Mercantile Exchange, which rose $2 to $80.45 a barrel
Monday before settling at $79.43, settled down 38 cents at
$79.05 Tuesday. [O/N] Natural gas futures gained 7.5 cents at
$4.67 per million BTU Monday but settled down 20.3 cents at
$4.467 per MMBtu Tuesday. [NGA/]
