Filed:

Jan 18, 2010

Appl. No.:

12/688972

Inventors:

Cintia Lapilli - Houston TX, US
David Nichols - Houston TX, US
Alfonso Gonzalez - Sugar Land TX, US

Assignee:

WesternGeco L.L.C. - Houston TX

International Classification:

G01V 1/00

US Classification:

367 73

Abstract:

A method for generating an illumination map. The method includes receiving an earth model that represents one or more properties of the earth. The method then includes receiving a target area in the earth model and propagating one or more wavefields from the target area to a potential seismic data acquisition region in the earth model. After propagating the wavefields, the method includes decomposing the propagated wavefields into one or more subsets of the propagated wavefields and creating the illumination map based on the subsets of the propagated wavefields. The illumination map may indicate one or more contributions of one or more synthetic source and receiver pairs for illuminating the target area in the earth model. The method may then include creating a seismic survey design based on the contributions.

International Classification:

G01V 136

US Classification:

367 38

Abstract:

A method for removing boundary-generated artifacts in synthetic and actual seismic data. After seismic data processing, undesirable boundary-generated artifacts appear in the final seismic section. To remove this unwanted noise from the section, zeros are added to the lower boundary of the seismic section. This essentially pushes the sources of the noise downward in time in the section. After padding with zeros, the seismic data is collapsed to their point sources of origin using the Stolt migration/diffraction algorithm. Once the data are collapsed, the size of the seismic section is reduced to its original size. Following the resizing of the section, the inverse of the earlier applied Stolt algorithm is applied to return the seismic data to its original form, minus the boundary-generated artifacts.

Abstract:

Systems, media, and methods for processing seismic data are disclosed. For example, in one embodiment, the method may include receiving a plurality of partial image partitions of a migrated seismic image, and stacking the plurality of partial image partitions such that a first image is generated. The method may also include aligning the plurality of partial image partitions based at least partially on the first image. Aligning may include adjusting at least one of the plurality of partial image partitions and generating a displacement field. The method may also include, based at least in part on the displacement field, stacking the plurality of aligned partial image partitions to generate a second image. The method may further include based at least in part on the second image, realigning the plurality of aligned partial image partitions.
