The 2nd to last announcement is confusing. They effectively state that they noticed the recovery rate and pressure was higher than expected for just the Upper Zone to be flowing back and basically realised that the pressure and flow was what was expected of both zones co-mingling, so drilled out the plug - no pressure change - all as expected - co-mingling was happening, yet they then mention about using artificial lift or shut-in if the pressure gets too low.

So what the hell happend for them to state about the possibility of pressure getting too low and artificial lift potentially being needed? The pressure and flow were as expected, and based on the recovery rate, 13% after 1 week, pressure and flow was as expected....

Then something changed dramatically....

The following week announcement states that the recovery rate went from 13% to 15% - and there it was - the reason why they stated about pressure getting too low and artificial stimulation being considered.

What happend shortly after they drilled out the plug to cause the pressure to drop.

I guess we may find out soon.
