Joe, I should have elaborated by saying, "The two [TX Eagle Ford and LA TMS] are talked about as being age-equivalent.  I think the use of "Eagle Ford" is for name recognition/investors and not for geologists/landowners.

Attached map shows Indigo II's ~ acreage focus in the TMS. Addtionally it shows the the 1 completed vertical, 1 drilling horizontal and 1 proposed horizontal.

Jay is correct. It has been out there for awhile.

Indigo is drilling the TMS. See attached cross-section. They are simply calling it eagleford to ride on the wave of success in South TX (publicity/marketing). Don't read into it anymore than that.

Jay,

 

I lump it in with the AC as a basinal unit. I know this goes agianst the conventional norm, but from the S.TX EGLFD logs I have seen the yellow highlighted section is equavalent. This is simply based on my experience. Take it with a grain of salt if you like.

Since the TMS is ~ 500-700' of gross thickness and the operators are only targeting the lower 200' I think it throws people off alittle.

I hate to share to much. Folks get cranky if you speculate.

The single well cross-section is from Avoyelles Parish.

Indigo is building the curve at 10544 the basin map shows the top of the EF at 10500 where Indigo is drilling. Looks to me like they are going into the EF.

Not sure what the "basin map" is? The well (on the attached cross-section above) less then 2 miles from them would disagree. A TVD of 10,600 would be just above the LT.

Basin Research Institute, LSU they are using a well as their example that was drilled in section 33-T5N-R5W and Indigo is drilling in 34-T5N-R5W. When I go back and look at that particular well it does show the Top od EF at 10,256 to 10,016 but the contour map shows it at 10,500.

Like I said take it with a grain of salt. I've correlated logs accross the state line and that is what I see. Not worried about it. I'm going fishing. Correlate you a few logs across. Names change very quickly along strike in the basin.

"Legacy Austin Chalk producing areas (e.g. Giddings Field) have not proven to be the best drilling targets for the Eagle Ford. One theory is the Eagle Ford Shale formation improves as you move south due to degradation of the Austin Chalk’s reservoir properties, which in turn means the Eagle Ford expelled less oil and retained more."

 

In other words, good AC prospect, poor EF prospect.  The EF is thought to be the source rock for the AC, just like the TMS is the source rock for the Lower and Upper Tusc.

An unconformity in a stratigraphic feature such as a broad erosion of an area can cause a significant gap in the stratigraphic record, but that is not what happened in this region.

 

Tight lines!

"Indigo Minerals announced their 2nd Tuscaloosa Marine Shale well today.  The well, Bentley Lumber 23H #1, is located in section 23, T5N-R5W, Rapides Parish, Louisiana.  It is permitted to a proposed total measured depth of 15,500' and is projected to include a 4,000' horizontal lateral section targeting the Tuscaloosa Marine Shale (they call Eagle Ford) at approximately 10,600' true vertical depth.  They state that the well is anticipated to be completed through the horizontal segment with 15 fracture stimulation stages."
