The recent "Sego Canyon road plan" story leads to several questions and cautions.
Oil shale and tar sands are very dirty fuels which require considerable energy to extract and process. To date they have been economically marginal at best. And they have always been environmentally disastrous.
Also, due to the growing awareness and concern about fossil fuel-fueled climate change, there is likely to be a significant carbon fee or tax imposed on all sources, leakages, and uses of fossil carbon-based fuels and products. Such fees or taxes are likely to start off small and ramp up rapidly. Some may hope and wish otherwise and lobby and work against carbon fees but the fees will eventually come.
