A seismic reflection study was performed across the Diamond Springs oil field in Allegan County, Michigan. The horizon of interest was the Middle Devonian Traverse Limestone located 1,700 feet in the subsurface. Within the Traverse Limestone are scattered patch reefs which characterize a targeted reservoir. The use of high-resolution, shallow seismic reflection techniques are useful for defining detailed subsurface porosity zones within the patch reef reservoirs.
Common source-offset profiling utilizing high-frequency sources and proper determination of field parameters are important in obtaining the desired optimum reflection. Also, the use of synthetic seismograms for modeling waveforms is essential for identifying the desired reflections. Finally, to prepare the reflection for interpretation, seismic processing by static and normal move-out corrections are applied. The final seismic cross-section can then be viewed with small porosity zones defined by "elliptical" shaped waveforms created by diffractions.
