April crude oil prices traded fractionally higher during the initial morning hours, as they reconciled North African/Middle East conflict against ideas that Saudi Arabia may make excess supplies available. There are a range of views on how much Libyan crude oil output has been reduced by recent unrest. The latest estimates from the IEA indicated that the country's 1.6 million per day of output has been reduced by 30 to 40%, with some experts suggesting over 70.0%. Meanwhile, the elevated tensions in the area took precedence over yesterday's EIA inventory data. EIA crude stocks rose 822,000 barrels during the report week to stand at 346.739 million barrels. Crude oil imports for the week stood at 8.106 million barrels per day compared to 8.266 million barrels the previous week. The refinery operating rate was 79.4%, down 1.8% from last week and compares to 81.17% last year and the five year average of 83.68%.
