So substitution of heavy, sour, for sweet, light, has five effects.
  1. We need more refineries to process the oil because it is sour and needs desulferisation.
  2. We need more barrels of oil to produce the same gallons of gasoline because it is hydrogen deficient.
  3. We need more barrels of oil in the new discovered and developed fields because we can't get as much of the oil out.
  4. We need more rigs to drill more wells to get the oil out because it moves to the wells at a slower rate.
  5. We need more tankers to move more barrels of oil for the same gallons of gasoline.
6. All of the above are directly proportional to the amount of ethyl alcohol i currently require to keep my head from exploding.

this is seriously getting scarier by the day. Every once in a while i just wish i could go back to the halcyon days before matt savinar infected me with this curse.

Might as well say that overall EROEI for heavier crudes => gasoline is considerable lower than for light crudes. Which is not good for prices, anyway.
