Maybe, when they go back to remove the plugs, they will let the kockatea clean up the completely first. This will give an accurate flow rate for it.
Then drill out the first plug and let the Caryingina fraccs clean up properly. They will clean up more easily than before if the Kockatea cleans out the pipe.
This will enable a stable flow to be calculated for the caryingina zone.
Then drill out the second plug etc. and repeat the process.
By the end we will have indivual flow rates for all our zones and an ouveall flow rate for the well.
That is when we will be patting NWE management and our selves on the back(and our wallets and purses).

All good fun .... as some else once posted .... "nerves and balls of steel".

Good luck all
