No matter how expensive crude becomes the Law of Receding Horizons tells us that substitutes will always be priced just out of range. Their production is, after all, subsidized by petroleum in the form of rigs, roads, labor, and indexed to inflating petroleum costs.
Even when crude rises to $500 or $1,000 unconventionals will remain a blip, a meaningless luxury reserved for generals or billionaires perhaps.
I'd like to suggest that before you insult posters you actually understand what it is they are trying to say? The point being made was that Green River oil shale is not the same as the "shale oil" that is being referenced elsewhere. The Green River shale is what is properly referred to as Kerogen shale. It is undercooked but full of organics. The idea has always been that by mining and cooking it you will get a substantial amount of oil. The technology is there, the cost/benefit doesn't fit at current prices/costs. Shale oil is something different entirely, it is oil already generated and sitting in either a liquid or gas state within the shales. Fraccing allows this oil to flow to the wellbore and even at current prices it is quite economical. The two are completely different, the economics governing both are completely different. The poster who suggested it was stupid to combine oil shales or kerogen shales with shale oil in any discussion is completely right. You, however, continue to be uneducated in the technology/science/economics of these endeavours but still love to post about how stupid everyone else is. Sad.
