Abstract: Use of Seismic Modeling for Reef Exploration in Michigan Basin

Waldo Jackson, Fred Hilterman

The large velocity contrast between shale, evaporites, and carbonate rocks, together with the relatively uniform geologic section of the Michigan basin, makes modeling a particularly useful technique for reef exploration.

Wave-equation models can be generated to aid in the determination of Previous HitfieldNext Hit parameters for optimum noise rejection and processing parameters. Previous HitExamplesNext Hit show that good surface-consistent static corrections are necessary to obtain Previous HitfieldNext Hit Previous HitdataNext Hit which are useful for model comparisons.

Previous HitExamplesNext Hit of Previous HitfieldNext Hit and model Previous HitdataNext Hit show good correspondence between the two. One-dimensional modeling using synthetic seismograms can be used very successfully to identify reflections and to predict the response of reefs in a particular area, for the response is very different depending on the presence or absence of salt in the sections. Two-dimensional models using Kirchoff wave theory are useful in determining the boundaries and thickness of reefs as well as in the detection of reefs. Three-dimensional Previous HitexamplesTop indicate the density of coverage necessary to detect reefs and aid in determining areal size.
