the German wikipedia explicitly mentions the complex extraction process which currnetly let it appear unlikely that in the forseeable future oil shale will be regarded as economically usable. Additionally, the winning and transforming of oil sand is easier, cheaper, and the mining, althoug opencast-mining too, is also less extravagantly.
To be considered as serious and economically valuable alternatives, both methods need world market prices for oil that we currently even do not imagine in our worst nightmares.  |
Wikipedia's facts are old and show an old method of extraction. Read the article for the new method as figured out by the good old Dutch!
They know how to do things once in a while.
