y2 update, page-3

From what I've read they seem to be a series of sandstone units interbedded with shale units and overlain by a thick shale (sealing) sequence. I don't know how many individual sands are present, possibly 3 or 4. They are probably fine-grained with reasonable porosity (pore spaces capable of holding gas) but fairly low permeability (linked pore-spaces which give a reservoir the ability to allow fluids to flow). There should be a gas column in Yulleroo of several hundred metres thick and it's a large structure so a lot of gas-in-place. They could get lucky with better quality reservoir in Y-2 than was penetrated in Y-1 and if so, and if plenty of pressure, it could produce quite well. High condensate content is expected so they won't need massive flowrates, like tens of mmcfd, to be economic. Probably a few mmcfd (say 3 to 6) would justify a permanent gas plant but they may need/want to drill some nearby look-alike structures before making that decision, imo.
