MINSLEY Earth Resources Laboratory Massachusetts Institute of Technology 42 Carleton St. Cambridge MA USA 02142 Abstract Synthetic seismic shot records were generated using a 3D elastic finite difference modeling code simulating the seismic scattering from sets of discrete large-scale vertical fractures in a subsurface reservoir. We used these shot records to develop data analysis methods applicable to reflection seismic field data in order to determine the orientation and density of the fractures. For shot records acquired parallel
