SONRIS Lite reports that the SWN BML PROP 31-22-1H in Ora Field spudded on 2/19/2012 and as of 2/20/2012 was drilling at 2185 feet.

I have not heard anything. At this stage you usually don't from what I hear.
Here is the latest report, dated 5/16/2012, from SONRIS Lite saying that, as of 5/9/2012, 45 isolation packers have been set in the Ora well, from 9138' to 14641'. Maybe The Baron or someone can decipher what this means. Could it be that they will try 44 or 45 perforation/frac stages over a 5500' lateral?

Thank you Obed. I hope The Baron does decipher what this means.
I'm no engineer, but it looks like they aregoing to try to do a lot of small fracks on this one.
Keep in mind they are still fooling around with a big science project here. We still have a lot of trial and error to see what will work, if anything.
The Garret well shows promise, but is still probally not commercialy viable. Decline is a big concern as well. Let remember the first few vertical completions produced well for a short time before petering out. The horz wells should hold up better... so we wil have to wait and see how they hold up.
How long does it take to do the frac jobs? Why so many?
They have 38+ Frac tanks sitting at this location and are going to begin moving them in today from what I undertand. The actual Frac job is not until the first week in June. Why so many frac tanks and why 45 packers?
38 tanks is a lot, but there have been wells with 100 or better used before. (In other plays) The amount of tanks used is usally based on how the frac water is being delivered to the location. The more of the water that is being trucked in, the more tanks because it's hard for trucks to deliver a steady flow to keep up with the frac pumps. Therefore, the higher amount of tanks allows for a "cushion" so that the frac crew is not waiting on more trucks to bring in water. If a frac job is being provided water by pumps, then they can usually get by with far less tanks. As the play moves along, especially once it becomes more of a production operation as opposed to exploriatory, cutting back on frac tanks will be done. As far as 45 packers, I can only guess that 44 wasn't enough... (Seriously, I don't have a clue on that one;-)
Are you saying they are only drilling this well as an exploriatory well?
At this point, all of the LSBD wells should be considered exploratory wells. The full geographic extent of the play has yet to be constrained, and the economic viability of the wells has not yet been proved.
We certainly are all hoping that there are economicly viable quantities of oil and gas down there, but this early in the play, nothing's certain.
I have no experience in fracking in horizontal wells but it seems reasonable to me that the engineers take into account degree of natural fracturing and rock mechanic properties of the formation. The well logs are the key to showing how a frac job will perform in this particular well. Remember that brown dense formation is heterogeneous. By doing numerous stages they can isolate smaller sections so that in the event that some stages may screen out during fracing there will be less hole lost due to screening out. Screening out occurs when proppant fails to enter created fractures in the rock. Depending upon how a frac goes in a given zone they may modify frac procedure according to how the frac seems to be performing.

AboutAs 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 |
