re: yr questions,

1) They should know next week the findings from the WL logs. Main thing is to know how the MDT jab goes as that will tell them about the pressure, drawdown potential/ mobility, permeability. Any sample collected from respective sands will be analysed for gas compo analysis (i.e CH4, CO2 etc etc). In short movable HC's are what the mkt wants to know about besides net thickness, avg porosity.

2) 9" casing point was around 3906m, 8.5" open hole depth is 4248m, So basically they've drilled 342m of new formation past the Kockatea Shale into the Dong/ W'gn sands. Run casing on TD & perforate it.

3) They cant stop & test these days, so have to drill to TD, then run casing & then pick the best Test intervals. Flow rates, WL logs, pressure readings will help in booking firm 2C per reservoir. This becomes 2P after FID is taken. So should b a priority to drill & flowtest the relevant sections.
4) Should start drilling sometime next week once WL logging is complete & assuming there r no mechanical issues etc. Once drilling resumes, they'll drill out of the Wagina sands into the Carynginia Formation, Irwin River Coal Measures & then into the Upper Kingia sands. Give that another 2wks. My timeline is around Easter for TD assuming no dramas, i.e., kick's/ sidetracks/fishing etc.

Hope this helps.
