A federal agency estimates that the Haynesville and Bossier formations collectively contain more than quadruple the amount of natural gas thought to be in place in 2010 as well as 4 billion barrels (Bbbl) of conventional oil resources.

Collectively, the Bossier and Haynesville assessments outstrip estimates made earlier in the decade of the Marcellus and Utica shales, making it the largest continuous natural gas assessment the U.S. Geological Survey (USGS) has ever conducted.

New evaluations of the Bossier and Haynesville, including onshore, state waters and a portion of the U.S. Gulf Coast, estimate mean natural gas of 304.4 trillion cubic feet (Tcf) and NGL of 1.9 Bbbl, according to updated USGS assessments. The assessments are predictions of estimated undiscovered, technically recoverable resources.

A 2010 assessment of the Bossier and Haynesville formations examined Jurassic and Cretaceous rocks of the Gulf Coast. At that time, the Bossier was estimated to contain a mean of 9 Tcf of natural gas and the Haynesville 61.4 Tcf.

“It’s amazing what a little more knowledge can yield,” said USGS scientist Stan Paxton, lead author of the assessment. “Since the 2010 assessment, we’ve gotten updated geologic maps, expanded production history and have a greater understanding of how these reservoirs evolved. All of that leads to a better geological model and therefore a more robust assessment.”

In 2011, the USGS estimated the Marcellus’ mean undiscovered natural gas resource of 84.2 Tcf and a mean undiscovered NGL resource of 3.4 Bbbl within the Appalachian Basin Province. In addition, a 2012 Utica assessment found it contained about a mean resource of 38 Tcf of undiscovered, technically recoverable natural gas.

Looks like the Haynesville will hold the title for at least another year...

A year or so, I would bet the same advanced understanding of the H'vill will also play out up north, and it as well will be much larger than expected.  

If it's any conciliation, I bet a higher percentage of the H'ville will be available to exploit versus being off limits due to government bans.

If the haynesville is so huge... won't that affect the price lower?

News like this doesn't usually affect price.  This is more of a geological exercise, in that it is an estimate on the geological size of the play.  It doesn't mean this gas is economical to get, especially at $3.  It does give one some confidence that the play is not a "flash in the pan". You may recall that when the plays around here first got started we would quite often hear anti-development folks warning of very short play lifetimes, that it would only be a few short years and the field would be an abandoned wasteland left unfit for anything.  This just kind of helps disprove all of that.

Agreed.  I think you are correct also about the confidence issue since we've been hearing the Haynesville was about done.

I'm by no means educated in the science aspect of it, but experience shows that several places have oil and gas that have been producing for decades.  And as technology progresses, those old plays are sometimes renewed with new ideas.  To say a play will only last a few years is somewhat short sighted.

So......where are they getting they getting the 1.2 Bbbl of oil in Bossier and 424 MMbbl of NGL in Bossier?

Not in Bossier but from the Bossier formation.  Keep in mind two things, 1. the USGS has always had difficulty separating the shale portion of the Haynesville Formation from the sand portion, and 2. the Bossier formation is the basil, or deepest, member of the Cotton Valley Sands group.  I do give the USGS some credit for belatedly coming up with a more accurate map that shows the shale portion of the basin does not extend into southwest Arkansas.

Bossier Shale that sits on top of the Haynesville?

The Bossier sits over the Haynesville regardless of whether we are talking about the shale portion of the basin or the sand portion of the basin.  Haynesville Sand production and Lower Cotton Valley production, which in some cases includes the Bossier Sand, often produces liquids.  There is a simple way to tell one from the other.  Where you find long lived, low decline vertical wells you have generally found the sand, not the shale.  There are exceptions for areas with low permeability such as the Terryville Complex where horizontal wells are more economic and produce meaningful liquid loads.

It is a government publication.  Enough said.
