Affixing numbers to specific units of fuel is actually pretty much precisely what happened under US Interior Secretary Harold Ickes and the "certificates of clearance" oil production quota system implemented by DOI and the Texas Railroad Commission (it confusingly neither regulated railroads nor was called by the sensible acronym, it's referred to as the TRO). This system was in place from 1933 until 1972, and effectively regulated the
global price and supply of oil over that period. Absent some initial hiccups and a slightly market disruption known as World War II, the result was a phenomenally stable price and match of oil to global demand from 1945 - 1973.
Daniel Yergin covers this in detail in chapter 13 of his truly epic history of oil, The Prize (1992).
