flow testing, page-2

There is a distinct difference between flowback and flow testing that you should factor into the mix.
Flow back involves flowing the frack fluids out, which is anticipated to take 10 to 14 days.
During this process of flowback increasing quantities of hydrocarbons flow if the reservoir makes contact. On completion of flowback (up to 4000 barrels of frack fluid) a relatively stable hydrocarbon flow is the aim.
We can be certain the frack fluid in the well bore will be lifted by the nitrogen gas lift, that part is straight physics. Less certain is the flow of frack fluid from reservoir into the wellbore, but there is good reason to be confident that reducing the pressure at the bottom of the wellbore (gas lift) will increase the frack fluid flow to the wellbore. I would not put a number on, confidence of success for the recovery of targeted frack fluid quantity, but with gas lift very high.
Then the numbers that really matter begin, with commencement of the flow testing program
