SB, I was under the impression that the shale was the Lower TMS.  Then again I just post these unit applications for the members that are interested in this particular play.  I pretty much stick to the HA/BO development activity.

Spring Branch,

 

Try this link for Tuscaloosa Marine Shale information.

SB,

You are correct. The TMS is above the Tusc. Those are Tuscaloosa well units that have been applied for. We will have another that will be applied for in the next month or so in East Baton Rouge. The pre-app is next Friday. It will be on a neighbor's property and I don't look for it to be good. That's a lot of drilling, 5 million or so, for a very small "hot spot". Don't quite understand what they are doing or why at the current price of gas. It will show what the TMS looks like in this area though.

What is the official state designation for a TMS unit if L TUSC RA is the Tuscaloosa Sand below the shale?

Skip,

That is a very good question. I'll get back to you on that. I'll ask that question at the pre-app meeting this coming Friday.

Thanks, Joe.  I've seen designations for the TUSC drilling units which use depths but never anything that indicated which were sand and which shale.  I guess it is possible that the small number of TMS wells drilled to date were permitted as non-unitized.

Skip,

I only know of one well that was drilled and produced as a TMS well. The guy that was scouting it for me said that once the frac was over the operator started locking the gate so he did not feel that he could go back to the site and there was no one around to talk to. I don't have a well serial number or name so can't go to Sonris. When all of this came up with the TMS in this area it kind of surprised me. We really have not had that much drilling or success in this formation to get this excited about it. I still think this may be a ruse and the main interest is Austin Chalk. All of this really got wound up on the East side of the river when Nelson/Pryme had good shows in the Deshotels. Just my opinion.

I have read that the TMS is very rich in organic matter but not rich enough in carbonate matter (CaCo3) to be effectively hydraulically fractured.  Is this statement valid?

Gray,

Great question.  I've posted a SWOT Analysis on our website relating to this.

In the sequence stratigraphic sense, the Tuscaloosa Marine Shale is in the Tuscaloosa "A" transgressive systems tract (TST). Being that you're transgressing out of the Tuscaloosa sands, the higher you go into the TST, the less silty you become.  The "A" TST is capped with a very clay rich shale at the max flooder surface (MFS).  So, the most brittle section will be in the basal portion of the TST where it is more silty.  In addition, as you move south and downdip in the play, you get more calcareous.  The basal part of the TST is known as the Pilot Lime in the deeper part of the trend. Hope this helps.

Does the trend get deeper on the southeastern or southwestern flank?

Spring Branch,

Here's a structure map on the base of the shale:

Gray,

I found 3 logs on SONRIS.  Send me an email to kabarrell@gmail.com, and I'll attached them on the reply.

You're 17 miles north/northeast from the Indigo well. TMS resistivities avg. 3 ohms which is low, but they are in the same range near the Indigo well, so lets see what happens with that well.

In your well, here are some formation tops:

-Top Selma Chalk: 7051

-Base Austin Chalk: 8870

-TMS: 9130-9380

-Top Lower Cretaceous: 9388
