Craig,

The AC is primarily an oil formation with some gas. The oil is a good gravity and sweet. It brings a very high price at the refinery. The chalk lies under the Wilcox and above the Eagle Ford with Eutaw separating Eagle Ford and TMS. The chalk is generally thicker (800-1000 ft) with each of the other two about 150-300 ft thick. As far as easier to get to or more productive somebody else will have to answer that. I think each has its own production characteristics and only time will tell which is easier to produce.

To Joe and the Group:

 

Google: An Unproven Unconventional Seven Billion Barrel Oil Resource - the Tuscaloosa Marine Shale        

The above reference article is a primer to the TMS.  It contains a stratigraphic chart and information/analysis based on well log data.  The Wilcox in "middle PCP" is most likely a "tight sands" formation from what I understand, and it could be another target zone???  The Austin (TX outcrop) or Selma (AL outcrop) Chalk is quite thick but there is a chalk zone just above the Eutaw (Eagle Ford) that has been tested with vertical wells in PCP.  From the top of the EF (just below the Chalk) to the bottom of the TMS is approx. 1,000 ft, but the "high resistive" shale zone that lies between the Upper and Lower Tusc. sands are the "hot spots" they're targeting first.  The thicknesses of these formations vary as to the depositional environment and whether they are updip or downdip of the Edwards Reef shelf.  That is my amateur geologist interpretation; buyer beware!  I hope this was helpful, though.  Please download the article, you will learn much.

Thanks Littleeasy and Joe. And good question Craig. 

Also, Little easy, please post the link to the article you reference again. Just hope I can understand it!

An Unproven Unconventional Seven Billion Barrel Oil Resource - the ...

 

I think the stratigraphic nomenclature for the area of interest; the structure maps; and isopach map data of the resistive section of the TMS (including "hotspots") should be informative - at least for discussion.  One can only hope that this is not a rip and run type play that is driven more by stock prices than commitment to develop the prospect.  Let's also hope that they will pull a rabbit out of the hat on Monday and avoid a "Black Friday."

Thanks littleasy I did not understand much but I am learning. I am praying that this economy can hold together. I have been waiting 30 year to get the oil of that land. Don't want to turn back now. I guess we will get a glimpse Sunday night from the CME.
