Myth: Processing shale oil uses vast amounts of water

Fact: 1:1 ratio of water used to oil produced

Producing shale oil uses less water than other industrial processes....

Myth: It takes more energy to produce shale oil than the energy content of the shale oil produced...
Energy Out/Energy In < 1
Myth (?): ...and, energy return on energy invested (EROI) is a valid method for comparing the merits of alternative energy sources...
SLIDE 13
So many variables and so many boundary decisions render comparisons meaningless
Fact: ...there is no widely accepted protocol for calculating EROI.
SLIDE 14
Imperatives:
- “…if the cost of energy required to produce
shale oil is greater than the market value of the shale oil produced, it won’t get produced.”
- [ref: Shell’s M. King Hubbert]
- If left in the ground, the energy benefit of oil
shale to society is ZERO.

Myth: Oil shale “explodes” like popcorn when heated (i.e., retorted)

Myth: Communities will not support

In Summary
- Myths and misconceptions continue to plague the
- il shale industry
- Proponents should:
- do good scientific work and subject it to peer
review
- be transparent – let the facts do the talking
- Shale oil is a legitimate option for our transport
fuel future
