Three structural traps in a Miocene Gulf of Mexico deltaic sequence. The updip one (right-most) and the downdip one (left-most) are downthrown closures set up by large south-dipping regional normal faults. The middle trap is an upthorn closure against an antithetic fault. Notice that the downthrown closures donot show any amplitude signature. The upthrown closure has a well developed amplitude with excellent structural fit. All three traps have been drilled: the downthrown traps are wet, the uptrown trap has gas pay.
