Marcellus plus Utica still no where near 10 trillion
That is alot of $$....so lets check on why it is probably incorrect.
it is about 2/3 of the entire USA GDP......so, lets look at how much reserves are estimated to be there and how much is estimated to be recoverable, even over the entire time of full development.
This is what the USGS has:
The Utica Shale contains about 38 trillion cubic feet of undiscovered, technically recoverable natural gas (at the mean estimate) according to the first assessment of this continuous (unconventional) natural gas accumulation by the U. S. Geological Survey. The Utica Shale has a mean of 940 million barrels of unconventional oil resources and a mean of 208 million barrels of unconventional natural gas liquids.
The Utica Shale lies beneath the Marcellus Shale, and both are part of the Appalachian Basin, which is the longest-producing petroleum province in the United States.
Marcellus is at 84 TCF of natural gas, is the largest unconventional gas basin USGS has assessed.
Now, you can just add up the TOTAL recoverable reserves and multiply by a unit value for oil &/or gas.......and estimate the aprox total value....and what do you get?
Then multiply by 2.91 for total economic activity (U of Tx. at Austin info), and it still does not come close.
The USGS is easy enough to check, just search Marcellus & Utica at their website, but the relevant recoverable reserve estimates are in the post above.
The Univ of Texas info that is relevant relates to Texas...and I used their numberof 2.91 times the value of production from thisspecific text:
"According to the Texas Comptroller’s input-output model of Texas’ economy, the total economic value of oil and gas is 2.91 times the value of production. Additionally, 19.1 jobs are created per million dollars of oil and gas production."
That comes from a publication posted on the internet from:
The Bureau of Economic Geology, established in 1909, is a research entity of The University of Texas at Austin that also functionsas the State Geological Survey.
It may be a little different in NY, OH, WVa, & Pa but Texas can be used as a good guide since they have a history of oil & gas records that goes back to 1909.
when you check to see how it all adds up (or does not add up)
.....you now have the references as well, if you need them.
