RE:RE:EIA Cushing report takes more than a couple of weeks to build tank storage. Also the remaining space at Cushing is already spoken for, At this point they will be forced to fill pipelines. There is about 20M bbls heading into the US from Saudia in the coming days.
US needs to start filling up the SPR which still has about 160M of free space, not sure how its divided between sweet and sour crude though so this number maybe way less. It looks like there has been no additions into the SPR yet.
