I am hoping someone with more knowledge can look at some of this presentation and give an opinion of it that the non-industry folks(me) can understand. Also shows both Bossier Shale and Haynesville Shale over the Sabine island in the cross section( A-A') page of the presentation.
Interesting presentation. Did you find any additional commentary files to go along with the slides?
Can you clarify your question regarding the Sabine Island diagram. Is it looking for some additional verification on whether the Bossier/Haynesville are indeed pinched out by the presence of the Sabine island feature? The diagram on the presentation does seem to offer some hope otherwise it seems...
One of the authors of this presentation is actually a neighbor and friend of mine here in Austin, so let me know further what exactly you are wanting to ask and I'll chat see if he can clarify further...
That would be my question to your neighbor, does the Sabine Island pinch out the shale or just pinch it. For all I can find out, we are either completly out of luck in that location, or things are ready to burst out of the ground as soon as Ole Jed fires off rounds in the right spot. As has been said here before, it is most likely best to follow the money. Range, Devon, EOG, Crimson are the money and are on the island with us.
I have been asking these same questions for some time . I doubt that the enormous amount of leaseing in both the central and southern areas of San Augustine and in Sabine County are exercises in futility. These guys are smart and not without the available technology.
What does Jay have to say on the subject? Is it as simple as.... is the Sabine Island a blessing or a curse?
Alongview: Some time ago you e-mailed a document to me which I thought showed the Haynesville
in the area we have questions.
It may be that the depth is an issue [oilvoice.com] not that the formations are not present.
P.S. I am going with the "blessing" and betting on the very smart OG guys.
CL, That map I sent to you was similar to the one from Chesapeake posted over in San Augustine. I can't locate it anymore.....must be a flaw in my filing system. The best signal I have seen for the presence of the Haynesville and the Bossier in Sabine County are the logs from the above presentation. It clearly shows the formation above the slope of the Sabine Island. The thing that I am not equipped to determine is, will it be economically productive? I would hope that you are correct in your thinking that these very capable companies would have steered clear of the risk instead of pushing forward with something like 200k+ acres of leases. They are still leasing as well, slowly but steady. Devon alone has taken almost 400 leases in Sabine County. Crimson and Samson have a bunch, Cabot and Southwestern have taken leases into 2009. Chesapeake has some leasehold in far North Sabine County and Encana was assigned a very large number of acres. Endeavor has a large leasehold in the NE part of the county. EOG has a presence as does Range Resources. Only time and the drill will tell us for sure but it would seem illogical that both San Augustine and Sabine Parish would be productive in the shale but the entire county sandwiched in between would be SOL. It is however very logical that the county with the least infrastructure would be the last to see the drill. Primary term leases are coming up by mid 2011 so we will see what it looks like before too long.
I was looking for some verification that the Bossier/Haynesville are indeed in Sabine County and not pinched out by the Sabine Island. The logs, although I can't interpret them in detail, seem to clearly show it is not.
I couldn't find any text or video to go along with the slides but it was certainly not for a lack of effort.
I guess if I had a question for your friend it would be in the evaluation of the two logs and cores from San Augustine and Sabine Counties; are they similar? and in his opinion, is Sabine likely to be productive to the same degree as San Augustine? Thanks for offering, I appreciate it.
The Haynesville Shale is a small world.....and you've got some pretty smart friends : )
Thanks for posting the presentation. It looks like the TOC (total organic content) is very good in the cores & I would really like to speak to the author sometime. I have some leases - might be good for the royalty owners since some companies are determined to "scare you to death" about the island. It appears that more-calcareous sediments take a frac better & the cores show not only good TOC, but good porosity & a good mix of calcareous materials. Thinner is better than nothing, and I wonder if - just by the boundary effect of harder material - if the fracs would be more contained & do a better job of cracking the shale open?
Funny you should bring this discussion forward today... I was talking with a friend this evening about the Sabine Island structure. The question we come up against is, how thin is too thin? And, does the Haynesville overlay the structure or does it pinch out on the flanks so that there is only the Bossier interval left?
As exciting as this is, we know that we have a responsibility to do this thing correctly. After all, we want the farm to remain a place where the family can gather for another 80 years and beyond. This site was born out of these desires. Before we started this site, googling "shale' brought up little information. Certainly nothing that was useful as we negotiated a lease. Read More
