>There are now two rigs turning in the Mako basin. Does this indicate that Exxon and MOL are confident in the economics of the project as they could have used one rig until the play was validated and then ramped up the activity.

They are probably trying to stay on schedule.

>I wonder if the Mako 4 and 7 wells will be included in the testing of flow rates in the springtime? Why not?

We don't know, but there are a few things to consider:

"No test shall be required in any wellbore that does not pass ExxonMobil’s due diligence studies of the technical feasibility and the integrity of the wellbores."

or perhaps this:

"Falcon may elect to reserve the Mako-7 to test zones and formations below the Szolnok formation at some time in the future."
