Yes, it has been a bit of a challenge trying to work out what fluids exist in the Pebbly Arkose and describe the history of fluids...best left alone for now. But I would first like to ask KiwiGeo and others if the clogging of the near wellbore with barite filter cake in M-1ST could have led to tight reservoir characteristics, and consequently supercharged pressure on the RCI tool? I have known supercharge to be around 100 - 200 psi, and is a different form of overpressure.
In your reply, "further down there may be heavy oil". Usually people say that we would only expect to encounter heavy oil in relatively shallow reservoirs, however gas condensate reservoirs have been found deeper down e.g 1000m - 3000m depth with an immobile tar mat or low mobility heavy oil beneath each gas condensate bearing layer
My feeling is the post Dande will not be heavy, instead it could be medium gravity with higher viscosity than in the Upper Angwa, possibly on the range 1 - 3 centipoise.
