Shell reported from their pilot plant project 3~4 times more energy returned from what was consumed.
And when you consider low cost natural gas consumed and a near light, sweet liquid petroleum returned, the economics are even better.
Not as good as energy/cost spent in the Bakken or Eagle Ford today, but profitable if permitted.
That’s still profitable EROI, but conventional gas wells have 8-10 to one ratios. Even .5:1 would be profitable to someone if there are no other sources ... but not many could afford the end product.
All this means is that the shale oil will be more expensive when it is sold.
