Gail, how does it look if you add in gasoline imports? Murray

These amounts include gasoline imports. The amounts represent the total amounts sold during the period.

One problem that comes up is that the monthly actual data and weekly estimates aren't exactly equivalent. The export amounts in the weekly amounts are EIA estimates, and historically these have tended to be too low. I have tried to adjust for this bias--recognizing that this bias may change or disappear, since export levels are likely changing now with the reduced world demand and the lower WTI price.

Nice to see demand by years (or product supplied or whatever you want to call it) stacked like that, much as the FHWA does with VMT:

Note that we bucked the usual downward trend in Dec. for some reason - more people tooling around dropping off resumes? And perhaps '09 will match '07 levels, as long as the cheap juice holds out. Or people have jobs to make money to buy the stuff in the first place.

For Product Demanded, a graph organized by PADD would be cool, using EIA Company Level Imports would be totally boss - you can sort the .xls any which way you want, by product or state or city or company or nation. 'Course, having made special docs for just the Pacific Coast states, I can testify that this is a real chore to prepare. Doesn't help that the sheets for 2001/2002 were formatted differently in certain repects than the rest - damned Bush appointees! That would be the tool to use for an insight into the impact of Gustav and Ike.

I am afraid I am not up for doing more graphs. If someone else would like to do them and post them, that would be great!

The stacked graphs are easy to do. If production amounts are displayed in a horizontal grid with months across for each year, as they are with the EIA data, Excel makes that type of chart easily.
