In other industry news, Hurricane Dean, which hit Mexico's Caribbean coast on Tuesday as a Category 5 event -- the most intense Atlantic storm to make landfall in 20 years -- has since weakened and been downgraded to a Category 1 storm.
As a Category 1 storm, it has maximum sustained winds of 85 miles per hour; earlier, Dean had packed winds near 165 miles per hour. Initially, it was feared that Dean might wreak havoc on oil facilities along Mexican and Texas coasts, but the current path has reportedly eased those worries.
