Non-unique seismic lithologic inversion for subterranean modeling

摘要: A method of modeling subsurface reservoir conditions deals with non-uniqueness seismic reflection signals respect to by proposing and then comparing both lithologic data for forward model sites select the most likely each site. Forward techniques are used build a synthetic trace catalog, which includes range corresponding pseudo-logs characteristics that could reasonably exist within defined region. Then in catalog is compared against every real trace, number (e.g., 10 50) traces selected association best match trace. Finally, site adjacent lithologically coherent pseudo-log at use generating display characteristics.
