oxx overpriced to the max, page-8

If I might extend the thinking a little further from the above post:

When I say that, in my view, Matuku is basically the single parameter uncertainty well this was said in reference to the F Sand target, and this was in relation to the uncertainty of migration path as in whether it has successfully passed through the underlying North Cape Shale.

However the deeper North Cape Sand may similarly also be considered as a target with single parameter uncertainty. The uncertainty this time is in reservoir. [There is almost certainly a near kitchen almost underlying structure and without any obvious shale horizons getting in the way of hydocarbon migration, however reservoir quality of the North Cape Sand is relatively uncertain.]

Therefore if each of the separate targets can be characterised as the higher class well, it follows that the COS for as least one success in Matuku is 1 - 1/2*1/2 = 3/4.
