Evening.
Who knows the reality but if you're talking about drilling deep through multiple horizons then, yes, the shot to my mind at least is that you can prove the positive (more oil) in one go but proving the negative (no more oil) will take a number of attempts, not just this currently in-progress drill and, yes, I dare say you're right that other horizons, over and above the big lumps already identified, could come into play too.
As already documented, the entire region is drowning in oil so "surprise hits" could well become a reality, if not on this drill then on future drills.
