Depending on the rig used, the capability to drill to the lower depths may not be a problem. The image above shows the deepest Top Kianga at 4000m.

STX drilled WE2 to 5100m for a conventional reservoir target which successfully flowed at 69mmscf/d. Such a drill is expensive and rig slots for those are likely harder to get.

Regardless of who would be doing the development of Grandis (TO, project sale or JV) it would come down to forecast return which would incorporate e.g. drainage area. That's why I wonder about the number of wells.

I understand 'normal' CSG is a lot shallower so uses cheaper, more readily available rigs and can be successful with numerous wells and smaller drainage areas per well along with more modest flow rates.

Maybe I'm over thinking the coverage/density of wells in relation to 'potentially 100s of wells' and in a full field development scenario it would land somewhere between conventional and CSG well spacing along with required flow rates for commercial success landing somewhere between the 2 field types... assuming the companies trying 'crack the code'. EXR 1st of course.

Nice one- don't think you're over thinking it at all.
Neil has referenced "500 well program" before....of course that's not an exact figure, more a representation that the potential for the plot could be multiples of 100s'.

Interestingly in the 1st graphic I posted above, study the number of CSG & Petroleum wells dug in the Trough in the zone between Roma in the sth west and Taroom in the nth east.
There's a lot!.....presume that's mostly APLNG permit areas?
