Seismic Interpretation Mitchum et al., 1977 SLIDE 21 After seismic acquisition and processing, we have seismic interpretation Here is where we take the images and deduce the subsurface geology This includes: Map faults and other structural features Map unconformities and other major stratal surfaces Interpret depositional environments Infer lithofacies from reflection patterns & velocities Predict ages of stratal units Examine elements of the HC systems AAPG©1977 reprinted with permission of the AAPG whose permission is required for further use. Determine the local geology from the subsurface images Map faults and other structural features Map unconformities and other major stratal surfaces Interpret depositional environments Infer lithofacies from reflection patterns & velocities Predict ages of stratal units Examine elements of the HC systems Courtesy of ExxonMobil L 5 – Seismic Method
