toe in the water question

Hi all, a distraction from why the sp has dipped.

I've been reading about the many oil fields in the Sergipe Alagoas Basin, and am starting to get an understanding of how you can seem to have so many players and so many fields. The geological sections I've seen so far show a rich diversity of trap settings. Does anyone know how the onshore sections compare to the offshore ones? Also, what are typical flows in this basin in discovery wells in the onshore section?
