That would make sense, if the data was being presented as BTU's. One would also have to adjust NGPL's, as they contain less BTU's per unit of volume (depending upon their makeup).

if we lived in a perfect world, we might also adjust ethanol volumes for poor EROEI. all useful factors to bear in mind.

although i certainly don't think ethanol will save us, it will probably provide a positive increment in total liquids this year (+ ~200 kb/d?). along with NGLs which are also growing rapidly, that will help to offset declining crude oil and condensate production and may prevent total liquids from declining for another year or two.
