FACTBOX: Ike shuts 22 pct of U.S. refining capacity

(Reuters) - Powerful Hurricane Ike bore down on the heart of the U.S. energy sector in Texas on Friday, leaving most U.S. Gulf of Mexico production idled and threatening a fifth of U.S. refining capacity with howling winds and a possible 20-foot wall of water.

Forecasters said the storm, packing winds of more than 100 mph, would likely hit near Houston early Saturday, after oil companies shut down about 25 percent of the nation's crude oil production and nearly 22 percent of its refined fuel production as a precaution.

The following outlines the impact of Ike on the energy sector:

***************************HIGHLIGHTS*************************

CUMULATIVE IMPACT OF GUSTAV AND IKE

*16.6 million barrels of crude oil

*81.8 billion cubic feet of natural gas

*20.9 million barrels of refining (counting only plants completely shut)

CURRENTLY SHUT/SLOWED

*97.5 pct Gulf of Mexico oil output

*94.4 pct Gulf of Mexico gas output

*14 refineries shut, 21.6 pct of US capacity

*3 refineries representing 5.1 pct of US capacity at reduced rates

*Most Gulf Coast pipelines, ports and waterways shut
