Thanks to everyone commenting on my Haynesville Lime questions.
Has anyone read the oilvoice.com entry dated 10/30/08 " CABOT OIL & GAS PROVIDES OPERATION UPDATE, ESTABLISHES 2009 PLAN".
[1] Cabot references their 1st Horizontal Bossier test well in the MInden area that was delayed....
Is this the Minden/East Texas opposed to Louisiana?
[2] Cabot goes on to reference another Horizontal from the same pad-site in the "Haynesville Lime".
Does any one know the names of these two Cabot wells?
[3] Has any one heard or read about any "Haynesville Lime" wells anywhere else other than the two Devon wells mentioned on this site?
[4] Does anyone have a clue as to why the wells have huge production rates?

Minden field is in east texas around small community Minden, TX--Rusk County--South of Henderson --run from Henderson south border by hwy 259 on the west and 84 to the south and east to the Shelby County line. This field some Pettit, TP and has excellent CV sands( avg dept ~ 10,750') which has been drilling in field for last 20+ years EUR ~ 1.5-2 BCF with 20-40 acre spacing for the tight CV sands, at bottom of CV the Taylor sands have been good in some spots. Recently drilling in some leases have drilled into the Shale ( mostly upper and lower Bossier Shale) between 10750 and 12500. COG has drilled some H wells in the Bossier and made good wells with EUR ~ 2-4.5BCF. and then 12500-14000' is the CV lime aka haynesville lime or smackover with EUR 2-3BCF per COG

Cheerleader, limestone formations can have very high permeabilities which could result in high production rates.

There is not a good detailed map of the Haynesville Shale, yet.

Jim,
I have been told that the Gray Sand was a Smackover. Is that not correct? I appreciate your knowledge.

On Petrohawk's most recent webcast (BankAmerica Conference), they stated that they were drilling a well to the Haynesville Lime (although they said they referred to it as the Cotton Valley Lime) in Shelby County. Is anyone aware of the Haynesville (Cotton Valley) Lime being as prolific anywhere else in recently drilled wells as it seems to be around the Stockman Field in Shelby County? Devon apparently stated that their two Haynesville Lime wells IP'd at 22 & 26 MMcf/day and didn 't have the rapid decline curves that the CV and Haynesville wells had.

Spring Branch,
On Oilvoice.com Read an entry dated 10/30/08."Cabot Oil and Gas Provides Operations Update, establishes 2009 Plan" They mention their 1st horizontal Bossier Test well in the "MInden area" which was delayed... etc. [Assuming this is Minden in Rusk County and not Louisiana.] Cabot continues to say they are going to drill a horizontal well from the same pad-site into the HAYNESVILLE LIME. I ask on another site the names of these wells...no answer. The latter will be interesting to watch for production.
According to this web site...the LIME is easier to fracture...
Also, if you access some of the other entries on oilvoice.com regarding the Haynesville Shale, particularly the comments regarding the HS in San Augustine and Sabine Counties, the comments are these two counties are the "Motherload" of the Haynesville Shale.
These LIME wells appear to be all in east Texas and larger than the HS wells in Louisiana
[ Can anyone site a LIME well in Louisiana?]
To my knowledge no LIME wells have been drilled in SA county or Sabine, but if some geologist on Oilvoice.com is correct, we should look for these LIME wells in both SA and Sabine counties. The LIME may top the March 08 Haynesville "Discovery".
Do you know the name of the Petrohawk well in Shelby and the location?

I hope this geologist is correct about SA and Sabine Counties. The thing that struck me most however about Devon's earnings call was that the cost of these lime wells is much less than the shale. 4-5 million vs. 6-8 million I believe is what they said. It would seem that if this is the case then they can drill and produce from these wells at a slightly lower gas price than say the shale yet come back for the shale when the price of gas goes back up. Seems like a win win to hold by production and reserve the shale for a more profitable time. Any thoughts.

Alongview,
The Haynesville Lime appears to have EVERYTHING going for it.
[1] Low cost for the wells
[2] Easier to fracture
[3] Huge monetary return
[4] Several OG's reporting completion or permits

I am interested in anyones point of view on any downsides because it appears there are none.
These LIME wells are the real winners and folks they are in EAST TEXAS!!!!!!

CL, They also seem to have less production fall off after the first year than the H'ville Shale wells. I agree that these could be the real bonus in this whole thing. Good post by the way. I have been waiting to read something positive for about six weeks now. Thanks!

Jim Krow & ALongview,
[1] I thought the LIME wells were less expensive than the HS which is one of the many attractions to the LIME? Why would the LIME wells be more expensive than the Haynesville wells, particularly if the LIME well is only vertical??
[2] In Devon's comments they did not know, I guess to date, if they could produce more on horizontal than vertical.
It appears that one of the many plus attractions to the LIME is that the OG's can produce XXXX vertical oppposed to going horizontal.
[3] I am trying to conceive the gigantic nature of one of these wells.
Jim Krow...is Devon saying it is POSSIBLE on a horizontal well to produce 66-100cf a day with a LIME well? If the reserve is present, is it physically possible for a LIME well to produce as much as 100cfd?????

If this production is a possiblity given the reserve...for all those in east Texas, who are regretting not signing.....be patient.

Are any OG's reporting any wells from a similar formation UNDER the Haynesville, in Louisiana?
