What I have heard of is that it responds much better to fracturization and easier to produce, it is a limey shale, I do not know if it is a resource play or not though, maybe someone above my pay grade could answer that one? As far as stratigraphy it is just under the Haynesville Shale. The three wells you mentioned were around Carthage and thus on the western edge of the play.

Jim, Are the requirements 640 acres for the Haynesville/Cotton Valley Lime?

Regarding the "Haynesville Lime"..
Does anyone know if there have been any confirmations of the 'Lime" in any other areas in east TEXAS?
Is anyone assuming that the Lime is under all of the Haynesville formation? If the "Lime" is under the HS and fractures easier, isn't the Lime the "find" and not the Haynesville Shale?
These wells appear to be larger than any HS wells that are producing in LA.
Does anyone interpret Cabot's statements that the Lime is also south of Carthage?

Cheerleader,
Dang, for a cheerleader, you ask some damn good questions. I, for one, am anxious to hear the answers.

Cheerleader, an area can have the Haynesville Limestone (Lime) but it may not necessarily contain gas. This is the same as the fact that not all sandstones contain gas (ie wet or full of water). The productive area for the Haynesville Shale covers a much larger area.

Grice,
Looks like they are referring to the Bossier Shale, Haynesville and the Smackover as the Haynesville Lime. And I agree, in that area, all formations could be considered differently. Just as the Haynesville Shale and the Haynesville Sand are different.

the haynesville lime is formation below the shale just above the salt. In Texas is aka as the cotton valley lime or smackover. It has good porosity and in some area a vertical well will drain 640 acres with time over 25-30 years. This formation as its name implies is Lime not a Sand or Shale so is not a very tight formstion/This gas is more likely to be sour gas. There are area in east texas that have eur of 7-8 BCF/ vertical well. XOM has several wells in the Overton Field in Smith and Rusk Counties with only one well per 640 acre unit in the Haynesville Lime some still producing 3-4 mmcf/month over 30 years of age. These wells have made 7-8 BCF over time

Thanks adubu. So it sounds like it is the same as what we call the Smackover in Louisiana?

BirdDawg, it can be be called Smackover Lime (Limestone) but this is different than the Smackover Sand (Sandstone). Similar to how there is Haynesville Shale, Haynesville Sand (Sandstone) and Haynesville Lime (Limestone) with each being different formations.
