Ann: West Erregulla Reserves Upgraded by 41%, page-27

Hadn't STX already booked reserves in this block before they drilled the well to TD (how??). The new release gives them another tick in the SP but I'm wondering how they have certified reserves when they haven't tested the well? Did they get samples and pressure data? Without pressure data, what GWC are they assuming and how can they confirm it's in communication with WE-5? there's already dispute about the GWC or perched water at WE-4. Feels like there's another capital raising coming - why else release a reserves update before you've got the data??
