yes dunder, I don't think it dawned on then, that the impermeable layer was there until Aug of last year, or there about, I suppose they were wondering why the gas was dwindling, first thinking it being compartmentalised then with water increasing and knowing they had a gross sixty metres gas interval, so trying to make sense of it all by referring to the KN-1 logs they then identify the impermeable layer separating the upper and lower zones. I think, maybe, who knows, fingers crossed, perforating the lower zone works : )

"KN-1 has intersected a substantial gas column in Lower Cretaceous sandstones,
the same reservoir that produces gas commercially in the neighbouring
Songo-Songo gas field. Electric logging has been completed and formation
pressures taken which confirm the presence of gas over a gross interval of
approximately sixty metres. This vertical well was drilled to a depth of 2030
metres (6,687 ft), ahead of schedule."
