Without nitpicking the numbers, you are probably right.
186MMCF is a bit less than 2/10 ths of 1 Bcf and last injection was 43 Bcf ??
If hits N of Miami on east coast and is not an "Andrew" probably would have little or no impact on Gulf production unless they shut down rigs on "uncertainty".
Do you know what the "average" Gulf production is ??
What do you look at for "spot" price ??
I have had "Fun" with this, but there a lot of the "Fundamental details" that I just don't know.
I still haven't figured out how much Ng is required to make up for a 1000MWe Nuclear plant going down !!
I have gotten as far as determining the "fuel of choice" right now would be Ng, in a Combined Cycle plant if the Utility has the choice, but as I posted before, when "flat out" they run/burn what ever they have !!!
Found some stuff on Coal prices, and it seems Ng around 4 ish is the clear winner.
