LI. 150 to 350 trillion cubic feet (Tcf).

Marcellus at 50 Tcf recoverable? Is that right? Is there a digit or a decimal missing in there?

Dion, Marcellus is +/- 500 Tcf and the North Field is > 1000 Tcf.

Les B:

Thanks for the clarification. The Marcellus was looking like less of a "Gasland" by the moment.

Btw, I had seen the field recoverable on Qatar North being upwards of a Qcf in other literature; is it independently confirmed, or is it an OPEC "we say its..." analysis?

The aerial extent of the Marcellus Shale is huge. Unfortunately much of it is pretty rough terrain for drilling operations. Probably it's most important attribute is its proximity to the best nat gas market in the U.S. As GHS members have come to consider a 10MMcfd IP well an average well not worthy of excitement, I offer this recent operator report from the Marcellus.

CNX Gas Co.
A horizontal Marcellus shale well by Pittsburgh-based CNX Gas Corp. is producing at a record rate for the company. According to IHS Inc., #GH2BCV Consol is in central Greene County, Pa., and produced an average rate of 4.9 million cu. ft. of gas per day during March 2010. The well was drilled to approximately 10,357 ft. with a horizontal lateral of 2,035 ft. and was hydraulically fractured in seven stages. The peak daily production rate was 5.7 million cu. ft. of gas, and current daily production is 5.5 million cu. ft. of gas. The company’s net Marcellus shale production is 21 million cu. ft. of gas per day from 16 horizontal wells. CNX has completed several horizontals in the area and has budgeted $110 million in 2010 for Marcellus shale drilling from a company-wide budget of $400 million. It plans to put two additional rigs to work in the area this year.

Although CNX is not one of the major shale players, it is quite acceptable for GHS members to state that their one well produces as much as all the CNX wells (16) in the Marcellus Play. I suspect that each Marcellus well is less expensive than a typical HS horizontal but I imagine that 16 of theirs are more costly than one of ours. So go ahead a feel superior. And cue Jack Blake.

Skip, it is likely that the Marcellus Shale wells will generate higher ROR's on average. The typical well recovers 3.5 Bcf with a $3.5MM cost and generates a 50-70% ROR.

Les,

Ouch! That makes it sound like the Haynesville isn't the "it" shale anymore.

Bobi, the Haynesville Shale will become the largest producing gas field in the US in 2.5 years and will hold that title for 10 years.

Dion, with ExxonMobil, Total and ConocoPhilips involvement I think it is a fairly valid number. The field will soon be producing about 6 Tcf per year.

What is the largest gas field in the world?

The North Field in Qatar.

LI, that area definitely looks great as T14N-R12W has seven wells on my top well list.
