Black Brush has workover rig on site...

Any other significant equipment?

Or just the rig?

Rock Man, I heard BB changing pipe out...different pipe before actual frack.

"Moving values"?

Valves?

Looks like today (Monday, 4/16) is the day.

Note this earlier posting from last week / problems with the casing

4 1/2" CSG. PARTED AT 6250' WHILE TESTING. WILL MOVE IN WORKOVER RIG AND PULL 6250'. WILL BACK OFF ADDITIONAL CSG @ 10,800' & PULL. WILL REPLACE W/ NEW STRING 4 1/2 15.10# P110 CASING AND TEST.

With the frac, have to assume they fixed the problem. But a lot more $$$$$$ spent to correct casing problem.

Based on the frac data posted, this is a very SMALL test. Only 1660' of the lateral being stimulated in the 9 intervals (about 184' per completion stage).

Proppant volume post is ultra small - only 258# per treated foot. Based on the info in the 20+ well summary I posted a few weeks ago, Operators in C Tx were pumping over 2400 pounds per treated foot (in the average) in their AC hz frac laterals.

I cannot find any info on EOG volumes in Avoyelles Parish but I would bet it is in the 2000+ pound range.

BB wells will be limited as to frac volume due to small casing size - just basic physics as what can be done with smaller diameter pipe.

We only get small summaries of info on SONRIS - I am hoping that the small frac volume on the BB is not tied to a failure of the casing during frac operations.

All this being said - I would caution all to temper their expectations as to post frac testing results on this well. A rule of thumb would be to look at the frac being only about 10 to 20% of the size of the fracs that are normally put on the AC.

So should post frac production be equally reduced?

I know that this is not a one to one comparison (frac approach to production results), but it does give one a reference point as to expectations in this wellbore.

Just my opinion on all this.

RM, wouldn't the frac stages be 134" (15930 - 14720 = 1210'/9 = 134.44').  If 427,500# is pumped per stage and a stage is 134', that would be about 3190# of proppant per linear foot of perforated lateral.  Please check my math.

Wow - stupid me / missed the "per stage" note plus did poor math on treated lateral length

The 3100#+ per foot number is correct - big frac "hammer" here.

Surprised that they can do that down 4.5" casing.

Apologize for posting bad info and comments!!

Still a pretty short section of lateral that is being treated. But some of the EOG C Tx AC Hz wells were only in the 2000' range too (and had great results!)

You double check me, I'll double check you.  Appreciate your professional opinions.
