Are you saying that the PCL source kitchen is different to the Shell one? In the fields I've seen, the source kitchen is normally a different location to the drilling sites and the oil has migrated to a reservour with a trap over it. Can you explain what the difference is between the source kitchens and how you have come to these conclusions. I haven't seen any oil migration models so if you have anything then please share.

My issue is not so much the working petroleum system due to the shell find nearby but whether the seal is intact or not for PCL. That you don't know until you drill.
