full development would be around 600m (say 8 wells at 40m each) + platform, and off the shelf packages processing on land.

They may not need to drill all 8 wells to start with - they may get away with just drilling say 4, which would save $160m or $24M of JKA's share. The remaining 4 could be drilled after first oil when the cash is coming in.

At any rate the idea isn't that JKA would need to cough up $90M at current SP. If the well is a success then JKA's SP will rise, they can raise the initial cash then.

Then as the project progresses their MC will increase and they may be able to fund the later wells either at favourable terms or even largely out of cashflow.

to me the well looks good, i would be surprised if it didn't flow enough.

Agreed, it looks good at this point. From a subsurface point of view the main risk now is probably how well connected the fractures are with each other.

If they're not properly connected the well may come on like the clappers but then fall off to nothing.

But I would be surprised if we don't get flow to surface on DST...
