" Each of the four planned fractures will be evaluated for flowback rates directly after the operation."

This most likely means that they will do one frac JOB, which consists of many STAGES, after which they will flow it back and do a short test. They will then do another frac job, which will consist of more stages....and then test those stages. This process will be repeated 4 times. After all 4 frac jobs are finished, they will do a long term flow test on everything.

"Once these fracture stimulations have been completed, ExxonMobil expects to enter into a test period"

On the Warro well, they didn't test after each frac job.

It took them 4 weeks to flow back the warro well, so if Exxon flows back each frac separately, it could be about 4 months before they actually start the long term flow testing.
