AKK don't usually say if anything bad goes wrong (in past they have just kept quiet - eg Birch 3 flowback), so hint of some difficult drilling this well means all did not go to plan.
"Hydrocarbons evidenced" (weak words) is not the same as first well statements.
Then fractures - caverns. Well if they are oil filled, that would be great news BUT difficult to cement...but they didn't say.
There will be no news on flowback rates/ IP until end OCT now imo...if they are only starting all 3 end Sep...so about 7 weeks away.
