The seismic response to four stratigraphic hydrocarbon traps has been analyzed using a microcomputer-based modeling system. This technique generates a suite of logs representing a gradual stratigraphic variation. Synthetic seismic traces are computed for each log and displayed as a model seismic section. The capabilities and limitations of the technique are illustrated by the following case histories: (1) Middle Devonian reefs in central Alberta, (2) Middle Devonian reefs in northwest Alberta, (3) Lower Cretaceous channel sands in eastern Alberta, and (4) Lower Cretaceous channel sands in southern Alberta.
