To be fair, I could do research - but now you're asking everyone who reads the post to do individual research. Why not have the poster do the research once and post results for everyone to see? Then everyone else will have a good starting point from which to add information. Quote Share this post Link to post Share on other sites

I think we need to start using metric figures for natural gas. A cubic foot doesn't amount to much. Or we could use cubic yards. Quote Share this post Link to post Share on other sites
D Coyne + 305 DC October 11, 2019 In July 2019 dry natural gas output was 2830 BCF, if we multiply by 12 to get an annual rate we have 34 TCF per year.  So 214 TCF takes care of US annual production for about 6.3 years. The earlier estimate of 70 years was off by an order of magnitude, fine for astronomy, not really acceptable in physics.  The Utica estimate seems very preliminary with F95 at 21 TCF, F50 at 97 TCF, and F5 at 281 TCF, the mean is 117 TCF but the range from F95 to F5 is a huge 260 TCF,  Compare with the Marcellus (where there has been a lot more drilling so there is far more known) where F95=34 TCF, F50=90 TCF, and F5=181 TCF with a mean of 96 TCF, the 90% confidence interval is 147 TCF, nearly 2 times smaller than the confidence interval for the Utica estimate.  Note also that these are technically recoverable undiscovered resources, even if we assume the are all "discovered" not all of this gas will be profitable to produce. Also there is very little detail in the Utica assessment which makes it a bit questionable. About 24 TCF of Marcellus estimate may have too low an EUR to be profitable. Quote Share this post Link to post Share on other sites
