Interesting. I really hope the Post Dande (200 level) will lead to an additional zone for future development. There was some talk of it being tight in M1, but would we expect tight sands at such a shallow depth? No, I would not. Compare with BP Khazzan tight gas sands which are 5 Km deep and they have to stimulate the wells (hydraulic fractures) because the permeability is around 0.1 mD (porosity 6%).
I think there is a greater probability of the Post-Dande containing viscous oil with possibly a gas cap above? Hopefully, the MDT will be able to drawdown on the oil, but there is also the NMR tool which can help determine if the oil is mobile. Of course there are methods such as hydraulic fracturing, horizontal wells and polymer flooding, which can help improve the oil recovery, if required.
I recall when I first started researching into Mukuyu, I came across an excellent report by Envoi Ltd "Project Introduction", dated 2019 (screenshot below). Figure 6 illustrates that there might be oil and a gas cap at those shallow depths:
