Encana has permitted to this formation in north Desoto. I have heard that Petrohawk has 2 test wells to the Smackover in south Caddo. Is this a 3rd gas formation or part of Bossier and or Haynesville?

Thanks for all the information. That certainly clears up some things for me.
I really like the article. It gives a ton of information. I really like the maps that go along with this. Shows how different things were during that time as compared to these. Perhaps all this will result in more driling
What would be considered good porosity & permeability of Smackover and Haynesville shale?
I think that might have a small amount to do with this. But the bigger picture is the getting unlocking the potential of the Smackover.
I just traveled from Shreveport to Frierson down ellerbe rd and 175 into Frierson and must have run over at least 10 cables running across the road during the trip. They are COVERING this area in seismic testing. Maybe this has something to do with what you all are talking about. I know they already know about gas, there is a pad every 1/4 mile.
It is kinda neat how they run those things. I had them in my yard for a time and right behind the house. I think it just helps the area get more marketable for the companies to come in and drill.
The SMK formation is below the gas plays. The SMK is usually oil but also contains gas which usually has some H2S. The gas may or may not be of value as it is expensive to clean the gas and get rid of the H2S. There is a big play in progress to see if the bottom of the SMK known as the brown dense can be produced. There is hydrocardbons in the brown dense. The only way to know what the SMK in your area is about is to find the top of the SMK. If the permit is near the top in depth, the well will be testing the top of the SMK. If the permit is for 500+ feet below the top of the SMK, the well is probably testing the brown dense at the bottome of the SMK. I have read that in some areas there are zones between the top and bottom that may hold hydrocarbons also. The key to what is going on is the depth. The Smk varies in depth, so you have to find the top in your area to have an idea of what is being looked for in the SMK. It sounds like some of the O&S companies that already have leases and gas production are getting permits to sneak down and get a look at the bown dense. By drilling to the bottom of the SMK, they can get a complete look at the SMK as it is a very thick formation and covers a very large area. Everything is very hush-hush on a new play.
The XTO permits in San Augustine and southern Shelby are the ones that intrigue me as they are Haynesville permits with 6000' laterals but to 21,000-22,000'. I guess maybe their parent company wants a look.
I'm pretty interested in some of the more recent wells in N.Central and NW Shelby as well. Many of these wells were permitted to first drill a "Test/Pilot" vertical hole very deep (16,000 - 20,000 Vertical Depth) prior to plugging back and completing the producing horizontal in HA/BO depths in the 10,000-11,000 Vertical Depth range.

The first few IP reports from some of these horizontal HA and BO wells have been pretty modest (1.5 mmcfd, 3.4 mmcfd, 6 mmcfd) but yet the leasing for this region is still VERY active.

Makes me think that there is something interesting in the well logs at those lower depths that keeps the O&G'S interested in that region in spite of the modest IP reports from these first few HA/BO wells.
That may or may not be true. The lease can contain a vertical Pugh clause reserving rights to the deepest depth produced during the primary term, rather than the deepest depth drilled.
I have noticed this on some of these wells and always thought it was confusing. As Spring Branch said how would the vertical Pugh clause impact this?
In the North Shongaloo-Redrock and Haynesville Fields area there are 3 zones of the Smackover which have been productive for many years. They are called "A", "B", and "C" zones. In some areas the "A" zone is missing. Every now and then someone takes a look at the brown dense. Once they "figure it out" I believe it will be productive in horizontal wells. We have no problems with H2S in my area and drilling is ongoing, after more than 50 years of activity. Currently XTO is active in area.
