20090240438 | System and method for migrating seismic data - A system and method that enable the processing of seismic data. In one embodiment, a system comprises a plurality of processing nodes and a server. The plurality of processing nodes are configured to process seismic data for migration. The server is operatively linked to each of the plurality of processing nodes to enable communication between the server and the processing nodes. The server may manage a set of stored beam tables that can be accessed by the processing nodes in order to process seismic data. | 09-24-2009 |

20100135115 | MULTIPLE ANISOTROPIC PARAMETER INVERSION FOR A TTI EARTH MODEL - A method for determining values of anisotropic model parameters of a Tilted Transversely Isotropic (TTI) Earth model, the anisotropic parameters including P-wave velocity (Vp | 06-03-2010 |

20110093203 | SYSTEM AND METHOD FOR CLUSTERING ARRIVALS OF SEISMIC ENERGY TO ENHANCE SUBSURFACE IMAGING - Seismic data acquired at or near a geologic volume of interest is processed. This may include forming an image of the geologic volume of interest from the seismic data. The seismic data may be processed by aggregating energy arrivals to reduce the number of imaging processes that must be performed to determine an image of the geologic volume of interest. This aggregation may be based on groupings of energy arrivals referred to herein as clusters. | 04-21-2011 |

20110103185 | SYSTEM AND METHOD FOR SEISMIC BEAM FORMATION THAT ACCOUNTS FOR EQUIPMENT MISALIGNMENT - Seismic data representing the propagation of seismic energy through a geologic volume of interest is processed. The seismic energy propagates through the geologic volume of interest from one or more source locations at or near the geologic volume of interest to one or more detector locations at or near the geologic volume of interest. In processing the seismic data, the seismic energy is modeled as beams (e.g., Gaussian beams). The processing performed (i) corrects for misalignment of the one or more source locations and/or the one or more detector locations with a regular, predetermined mesh, and (ii) steers the seismic data based on the modeled beams. | 05-05-2011 |

20110205846 | SYSTEM AND METHOD FOR ATTENUATING ALIASING IN SEISMIC DATA CAUSED BY ACQUISITION GEOMETRY - Seismic data representing the propagation of seismic energy through a geologic volume of interest is processed. The seismic energy propagates through the geologic volume of interest from one or more source locations at or near the geologic volume of interest to one or more detector locations at or near the geologic volume of interest. In processing the seismic data, the seismic energy is modeled as beams (e.g., Gaussian beams). The processing includes determining a filter for the seismic data that attenuates aliasing which may be present in the seismic data due to spacing between detector locations. | 08-25-2011 |

20110211761 | SURFACE SMOOTHING WITHIN AN EARTH MODEL OF A GEOLOGICAL VOLUME OF INTEREST - Surfaces may be smoothed within an earth model of a geological volume of interest. More specifically, smoothing may be done on a specific surface by smoothing or otherwise altering dip values without changing the position of the surface within the earth model. Dip values may determine certain behaviors of a surface such as reflection and refraction of seismic energy propagating within the earth model. | 09-01-2011 |

20110320129 | SHOT GATHER DATA BEAMER AND DEBEAMER - Beamed data can be obtained from shot gather data, and debeamed data can be obtained from beamed data. Shot gather data for a geophysical volume of interest in a first domain and/or beamed data in a third domain may be received. The first domain has a component relating to seismic wave propagation time and a spatial component relating to lateral spacing. The third domain has a component relating to local plane wave arrival time at a beam center surface location and a component relating to plane wave arrival directions. Data may be transformed between the first domain and a second domain. The second domain has a frequency component and a spatial component corresponding to the spatial component of the first domain. Data may be weighted and/or deweighted in the second domain using a weighting function. A forward transform may be applied to weighted shot gather data in the first domain to obtain beamed data in the third domain. A reverse transform may be applied to beamed data in the third domain to obtain weighted debeamed data in the first domain. | 12-29-2011 |

20120185171 | MULTIPLE ANISOTROPIC PARAMETER INVERSION FOR A TTI EARTH MODEL USING WELL DATA - A method for determining values of anisotropic model parameters of a Tilted Transversely Isotropic (TTI) Earth model, the method including obtaining an initial TTI earth model that substantially flattens common-imaging-point gathers and substantially ties seismic data to well data; inputting checkshot data and/or VSP data to determine updated values of Vp | 07-19-2012 |

20120243371 | SYSTEM AND METHOD FOR SEISMIC DATA MODELING AND MIGRATION - A system and computer-implemented method for accounting for temporal dispersion in low-order finite difference seismic wave propagation is disclosed. An embodiment of the method includes transforming a seismic dataset from time domain to frequency domain to obtain a frequency-domain seismic dataset, applying a frequency-domain time varying filter to the frequency-domain seismic dataset to obtain a filtered frequency-domain seismic dataset, and transforming the filtered frequency-domain seismic dataset from the frequency domain to the time domain to obtain a time-domain filtered seismic dataset. The frequency-domain time varying filter is based on the effective phase velocity inherent in a finite-difference solution to the wave equation. The frequency-domain time varying filter may be applied to a synthetic seismic dataset that was generated by low-order finite difference modeling. A different frequency-domain time varying filter may be applied to recorded seismic data prior to reverse time migration. | 09-27-2012 |
