In a conventional reservoir, perched water can be identified and understood - but my concern here is that in fractured reservoir, it is virtually impossible to identify all the fractures and how they behave. If there are many areas of perched water, then high water cuts could be an ongoing feature of the reservoir and would always limit oil production.
After so long, so many wells, so much seismic - we are still debating something so basic as where is the water coming from.....this shows just how uncertain this type of field is. As I have said a few times, if it was onshore you could keep drilling. West of Shetland with its short weather window and expensive wells - it has to work early on or you just keep putting good money after bad. The results could just keep showing there is oil and there is water and we really don't understand what comes from where
