As mentioned earlier there's a lot of drilling mud to clear from the reservoir and we weren't told what mud weight they were using. From my VERY limited knowledge of drilling tech I'd expect wellhead pressure to gradually increase as mud gets unloaded because a mud column must be a lot heavier to lift than a methane one, then we should get some meaningful indications. Looks like a couple more days before we'll know. My tuppence worth: I think they'll get some sort of gas flows out of upper Nullara but at what pressure and what else might be there is a mystery. I don't recall mention of the Nullara at Valentine being vuggy (vugular) when they intersected it there, so maybe it's patchy. That makes it anybody's guess how big any fluid (gas/oil/water) accumulation will turn out to be. I guess they'll need to extended test it if it seems worth the cost & effort? Expert comment needed (I'm no expert on these questions)!
