Generating an image of a subterranean structure

摘要

Different values of at least one migration parameter are selected. An imaging technique is applied a plurality of times, where each application of the imaging technique uses a corresponding different one of the different values. Each application of the imaging technique produces a corresponding image of a subterranean structure. An aggregate of the images is computed to produce an output image of the subterranean structure.

1. A method comprising:
using a random number generator algorithm to generate a first and second set of migration parameters for vertical seismic profiling imaging; applying a vertical seismic profiling imaging technique by migration using the first set of migration parameters to a set of seismic data to generate a first image of a subterranean structure; applying the vertical seismic profiling imaging technique by migration using the second set of migration parameters to the set of seismic data to generate a second image of the subterranean structure; aggregating, using a system having a processor, the first and second images to generate a third image of the subterranean structure; and using the third image to identify one or more reservoirs, aquifers, injection zones, or combinations thereof in the subterranean structure.
