The above graphs shows US liquid fuel production, 1980-2011, broken out into its major components...You can see that at this point a large fraction of the liquid fuel numbers are not actually crude coming out of the ground.
This next picture shows the same data but putting the non C&C components onto the other axis so that they are not stacked on top of the C&C line:
This makes it clear that most of the production resurgence of recent years has come from the non-crude components. Biofuels have made the largest contribution, but NGLs and refinery gains have contributed also.
