Doesn't the Shell process involve injecting steam?
I think recent times do suggest that oil companies will need to moderate prices if they do not want alternate sources used and developed more rapidly. I have always been confused as to why politicians in the dry southwest seem to have jumped on that bandwagon. What would people choose water or oil? The water usage required should be a bigger part of the debate. Erik "Currently, oil shale extraction and processing require several barrels of
water for each barrel of oil produced, though some of the water can be recycled." See http://ostseis.anl.gov/guide/oilshale/index.cfm I am not sure if Shell's new in-situ process requires as much water.

Don can answer this, a newspaper article said it currently takes 2 barrels of water for every barrel of oil from the shale deposits. Is this true?
Just a note on oil shale. It will take far too much energy just to
extract oil from shale. And even worse, it will use up precious water sources we cannot afford to use in the process.
