Alan,

I figured it was a link to a server, but then what do I know beyond surfing the net.

Yes, interesting stuff, to be sure. Yet it's somewhat dated per the gov research (per our tax dollars) having been done over six years ago, back in 2012, and since some of the research for such a lengthy article was probably compiled over seven years ago before its publication date. And though the actual geology hasn't changed, the intel on the well logs possibly has per more exploratory drilling. Why else would COP and EOG, etc., be leasing in areas that are not highlighted in the assessment units?

Jesse, I don't understand the fascination that COP has with the area above the shelf. That seems to be their focus. My understanding is they are only interested in the area between St. Francisville and Clinton.This research clearly states that the production above the shelf will be spotty and slim to none. I agree. We leased yesterday because I feel EOG and COP are going to kill the play before it gets started. I'm glad the land owners up their got good leases but a few dry holes will kill us all I'm afraid. This research paper is not dated - it is current. The geology has not changed. The esoteric stimulation that EOG is using is not necessary or wise.

Joe, 

You're not giving recognizance to drilling innovations since 2000.

The AC a real crapshoot as nobody knows for sure what's down there in any given unit, but if I had to guess, I would say at this point in time:

        1.  The fat lady will sing this time around and

        2.  Turkeys will fly.

Let me add that back in the day that virtually all laterals had some degree of collapse downhole in the Masters Creek/Pitkin/Sugartown fields, and that product remains in the ground. Some wells had more collapse than others and thus might have contributed to decline rates of affected wells. Slotted liners may have helped if the collapse of hydrocarbon markets had not killed the play.

I don't have any idea what the reference to the fat lady and turkeys will fly has to do with anything in reference to the AC. I'm just stating what I read in the research report. Its also interesting that they state that the formation is different in the East then in the West. That opens the question of what is the true composition of the AC. Is it chalk or chalk with a high degree of clay to the East. Then on the other hand is it really chalk - Calcium Carbonate (CaCO4) or is it Gypsum (CaSO4). If its gypsum then there  is a water component to the formation. That would make a great difference in what should be done to enhance the production. A lot of work needs to be done on finding what the true composition and nature is of the formation in this area. I only skimmed the report. From what I see it is a very good piece of research.

Joe,

Those statements are a reflection of my take the AC could well "play" if not sabotaged by "clay". 

The E&P's most likely know from previous drilling the composition of the AC in Masters Creek and Sugartown. Three old wells that hit the AC in the 70's may give further data useful in bridging the gap to the Brookeland Field on the TX/LA border. It's a question now whether they will be coming on with an aggressive drilling program, or the aggressive flipping of leaseholds. 

The well tests on the Eagles Ranch 14 H in Avoyelles Parish are going to be very, very telling.

So Bob , when and if might we hear about the well test , core, rock, logging on the Eagle Ranch well?

will it ever be public data?

There is some limited data posted on the SONRIS site concerning the Eagles Ranch well. Don't now if I just missed it earlier, or if it is posted new.

The operator got a work permit to frack and produce the well last August:

<PERF & FRACK PERF CLUSTERS IN HORIZONTAL SECTION F/16275' (UPPERMOST PERF) TO 20563' (LOWERMOST PERF), DRILL OUT CBP'S & PRODUCE WELL>>>

Hard to tell if the frack job was really performed. Production and test data are limited to date. The well is showing a rapid decline evidenced by the production figures.

Oil decline 12,201 BBL's in the last quarter of 2017, gas likewise declined by over 13,000 MCF.

Is this the typical rapid decline scenario brought to our attention earlier by Rock Man, or what is the operator trying to hide in not timely reporting production to Conservation?

Bob, maybe there's a chemical treatment that can counteract the clay's tendency to clog up the fractures/matrix/etc. Seems to me that such well protocols could evolve with the application of improved geochemistry, i.e., sharp operators might be willing to try something new.

Jesse,

When an AC well would start clogging up, UPR and others in the last play would acidize it and get the affected well going again. I can't say exactly what went on downhole, but I know it was an unexpected and unwanted expense for the operators. Sometimes a well would require repeated acidizing to stay in production. There were similar problems with the water injection wells that populated each drill site.

I suspect many operators would like to try some new techniques in the AC if oil was $100/bbl again.
