Where are the US SPR inventories reported?  I would like to monitor them also.  
The U.S. SPR inventories are reported in the Weekly Petroleum Status Report issued by the EIA.  The latest balance sheet, which automatically updates each Wednesday morning, can be found here: U.S. Petroleum Balance Sheet.  The amount stored in the SPR dropped for quite awhile, but 700,000 barrels were added in the week ending 11/25.  
Thanks for replying and correcting. It was the previous week it had dropped 0.3.
