Different margin types in basins have different play types determined by the geometry and history of the margin. [[:file:exploring-for-stratigraphic-traps_fig21-38.png|Figure 2]] shows play types for shelf-edge and ramp margins.

Unpublished data (courtesy Amoco Production Company) derived from cores and [[seismic data]] were used to build an integrated lithofacies map. [[:file:exploring-for-stratigraphic-traps_fig21-39.png|Figure 3]] is a cross section representing the reservoir properties from representative [[capillary pressure]] data. The facies belts shown in the map above the cross section were deposited during maximum highstand of the Ismay (Pennsylvanian) carbonates. The fades are superimposed on an isopach map of the highstand systems tract. Test and show data overlain on the map show that significant reservoirs are restricted generally in the ''Ivanovia'' algal mound buildups, which flank a highstand basin shown in gray.
