Wow it looks like we're going off a cliff in that first graphic! No wonder they're drilling the DFW airport!
I am also curious about Figure 1.  Dave, know why there is such a big dip in '06?
You'd have to ask IHS Energy. It's either a mistake or things are going to hell in a handbasket.

There was a big dip because storage was (is) full at 3.2 tcf and there was no place to pump the produced(!) the gas. That is why some producers shut wells and also returned rigs.

! produced = extracted from the guts of the earth.

I think the 3.2 tcf is the 5 year average.  The eia says the weekly is ~3.45 tcf.  Also, the storage capacity I found on the eia web page is 8+ tcf as of 2004.  If thats correct we aren't anywhere near storage capacity.  Maybe thats not the right figure though.  Where did you get the 3.2 tcf for total storage capacity?
Well my number was not well researched but from memory and press reports. I seemed to remember 3.2 but it may have been 3.45 tcf. The reports said that production was being shut in due to lack of storage capacity. I did not try to verify what the true storage capacity was.

From what I remember some of the bigger players had shut in some wells - at least that is what was reported.

Last weeks report was 3.450 Tcf.  I heard max was ~3.5 Tcf.

Found this eia pdf that says the "working" storage capacity is something like 3.6 tcf.  So more than 3.45 but not too far off.
