Seismic data were collected in the northern Michigan reef trend, an area containing numerous small pinnacle reefs. The surface topography is flat, but it contains deep erosional valleys filled with glacial drift which produce time shifts in the data. The data were processed without static correlations. To predict the effect of static errors, a model was designed to produce data resembling those taken over a pinnacle reef. Seismic data was collected over this model by a method simulating the crossed array technique. Horizontal displays of the power envelope and the instantaneous phase of the migrated data were generated at a specified one-way time, when various source and receiver dependent statics has been introduced into the raw data. The statics were designed to simulate the effect of glacial drift.--Modified journal abstract.
