"The amount of oil sitting in source shales is greater than all the oil that has migrated out, been trapped and exploited since the industrial revolution. It's all a matter of cost."
Do you have proof of that because all the research I have read says the opposite.
The cost of Fraccing for oil is very high and lots of drilling companies come and go. There is also the problem of transport which adds significantly to the cost especially in the mid to lower US fields.
The studies that I have read say that oil from Fraccing will be mostly gone in the next 10 years and will fall off significantly.
