* An isopach map of the target reservoir—especially important if the reservoir displays significant stratigraphic thickness variation or has behaved in a ductile or compactive manner during deformation.

* Two or more structural cross sections incorporating all surface and subsurface control (wells and seismic) projected into the line of section in both the strike and dip directions.

* Two or more structural [[cross section]]s incorporating all surface and subsurface control (wells and seismic) projected into the line of section in both the strike and dip directions.

* Fault-surface maps (structural contours on the fault plane), made for all faults critical to closure at the top of the reservoir.
