RE: Flowrate15 Dec 2022 20:57
Treat this as more fun than fact please, but gives an idea on frack water tankers to count.
PANR have stated “Typically, a better indication of ultimate production performance can be ascertained after recovering over 40% of the frac fluid”
Typically, so not fixed in stone, oil flow rate is the ultimate test.
I had a crack at estimating the volume of injected frack water a while back, and came up with a minimum of 50,000 barrels. It was subject to a few assumptions, such as only using the available stored water on site.
With new facts emerging, 12” make up water supply hose, and 10,000,000 lbs of proppant delivered, that assumption has to change, and also include make up water supply during the fracturing of stages.
Calculating from a different perspective, proppant is blended into slick water at a range from 0.25 to 4lbs/gallon, with the norm around 1.2lbs/gallon.
Based on that the 10m lbs infers 8.3m gallons
That is 198413 barrels injected, the recovery target at 40% is 79365 barrels
Prior to shut down for proppant clean out (12.5%) 24802 barrels had been recovered, leaving another 54563 to come after restart.
At 190 barrels/tanker load, it requires 287 trips
More assumptions (errors ??) an average 1900 frack water barrels are recovered/day, 10 tanker loads daily to dispose of off site, 29 days to achieve the 40%
We have strong flare flow pictures from the 5th December, indicating good reservoir contact, so look to be well ahead on this,
Obviously so many what ifs , did all the proppant get used, perhaps only 90%, what if proppant ratio is 2lbs/gallon etc
