Multimode reverse time VSP imaging over complex structures at Yucca Mountain, Nye County, Nevada
- Colorado School of Mines, Golden, CO (United States)
With VSP (Vertical Seismic Profiling) data, variable density plots of its observed, recorded wavefield reveal little about the nearby geologic structure. Considerable structural information is contained in the reflected events, but migration or some similar procedure is needed to image the reflectors and create an interpretable display of the structure. The authors have succeeded in imaging reflectors by reverse time wave equation migration in a physical elastic model of a simple fault, and in a complex physical 2-D scale model of Yucca Mountain, Nye County, Nevada. All four modes: P-P, P-S, S-P, and S-S can be imaged. Images are generated by forward scattered as well as back scattered events. The images compare favorably with the models can demonstrate the efficacy of the technique in VSP processing and interpretation.
