The SONRIS report was filed in the middle of the fracing process and only included the first stage. Subsequent reports will included the other Perf intervals. When the well is complete there will be a report in the well file on SONRIS Classic that gives the frac design in greater detail. You can pick a nearby completed well by the same operator and review it while you wait for the completion report on this well.

Robert, I believe you are just seeing a partial report in Sonris. Once the entire report is available you will see how the perf/frac stages are done one after another starting at the end of the lateral and working back toward the curve. I have attached an example for your reference.

Iam sure many parameters are monitored during the frac process to control the process but the full effectiveness of frac procedure will only be known once completed and the well flow test performed.

Thanks much Skip and Les!
I did not realize that perforating and fracturing would occur in cycles, as shown in the Caney Creek well report. I am still curious/puzzled as to why there would be a frac "set" of only 3' in length, but I guess that may be more common than I realize. I have been using SONRIS Lite a reasonable amount, but not SONRIS Classic; looks like I now have incentive.
Thanks again - Bob

Robert, that one set of perfs probably does not represent the full perforated interval for the 1st frac stage.

Hi Les,
Okay, got it. A "set" is not a "stage". I learned a few significant points today. Just plowing around in sonris, looks like the next couple of months should be exciting for us folks in the SE quadrant of RRP.

I have heard that a very small perf & frac is done near the end of the lateral on most horizontal wells to help with getting the tools in and out of the hole during the main perf & frac job, since they use liquid to assist the tools in and out. When they are done I assume they would set a plug to isolate this area.

Like I said, "I heard".

Interesting, and certainly makes sense; I am gaining a finer appreciation of how sonris input can look significantly different depending on the exact point in the process when it is taken. Thanks! - Bob

Robert, yes - there are 7 wells in T12N-R9W and 1 well in T12N-R8W that have been completed but test results have not been posted.

The two test rates posted in T12N-R9W both look very good.

Shell, Lem Jones 9 #H1 Well, Serial #240886, S9-T12N-R9W, Red River Parish, 14532 Mcfd, 20/64" Choke, 8828 psi Flowing Pressure

EnCana, Joanna Carson 4 #H1 Well, Serial #240295, S4-T12N-R9W, Red River Parish, 23884 Mcfd, 22/64" Choke, 8678 psi Flowing Pressure

Hi Les,
Yes, thanks, I have seen those two wells, and they seem encouraging to me - seems I remember you wrote somewhere that wells coming in over 8000 psi flowing pressure are excellent, or some such. I don't know if some folks might get the scout reports early on the others, but I will be all ears. Seems like the sonris lagtime has gone down a bit too, though.
Best regards - Bob
