From Falcon:

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

From Transerv releases on the Warro well:

March 31, " The full fracture stimulation program will comprise 5 separate fracture jobs"

April 21, " The frac program achieved seven fracture stimulation stages"

Note the difference between a "fracture job" and a "fracture stage". It's not clear if Exxon is doing 4 frac jobs or 4 frac stages on the F1.
