...allow me to finish this for you, if I may.
Not to rain on your parade but "shale oil" and petroleum derived from fracking shale formations are two different things. There is no "shale oil" currently being processed in US refineries.
If in-situ shale oil extraction was currently technically and economically feasible (it's not, the process used in Canada is ex-situ) there would still be the problem of where all the water required to process it would come from. In a state lke Colorado, that much water is a big deal, and someone would have to give theirs up.
...or it would have to be piped to the water, where facilities already exist.
Allow me to elucidate, if I may.
"Shale oil" is not in liquid form, so it can't be put in a pipeline until it's extracted from the shale.
Besides that little stumbling block, in Colorado most of it's too deep to be economically mined, processed, and extracted at the surface so the oil has to be extracted in-situ. This requires huge amounts of water, heat, and energy.
Like I said, if it was technically and economically feasible on a commercial scale, the oil companies would be all over it. They're not.
