    摘要: A method (800) for processing seismic data may include receiving input seismic data (d i ) comprising N spatial coordinates, where the input seismic data is in a first spatial domain, expanding the N spatial coordinates of the input seismic data (d i ) to N' modified spatial coordinates, where N' is greater than N, to provide spatially expanded seismic data (d e ) that is in a second spatial domain, transforming the spatially expanded seismic data (d e ) to a model domain to provide model domain data (d m ), and generating a final image (d f ) of a subsurface using the model domain data (d m ). A corresponding computing device (1100) is also disclosed herein.

    摘要: Computing device, computer instructions and method for correcting an image, of a surveyed surface, due to a free-surface reflection. The method includes calculating (706) a free surface reflection operator for a seismic source displaced in water (120) based on a position of the source, and an air-water interface datum (234); receiving (708) recorded seismic data d recorded with seismic sensors (r), wherein the recorded seismic data is associated with a pressure and/or a particle motion produced by a seismic wave in earth; correcting (710) the recorded seismic data d based on the free surface reflection operator to obtain transformed seismic data; and generating (712) an image of the surveyed subsurface, based on the transformed seismic data, wherein the image is indicative of various layers of the earth. The free surface reflection operator varies while a source signal is being emitted by the source.

    摘要: Synthetic survey data is generated using a two-way or one-way wave propagator based on a current model of a target structure. The current model is modified to reduce a difference between the synthetic survey data and observed survey data, while maintaining unchanged a velocity component of the current model, where the modifying of the current model produces a modified model. The modified model is used to reduce an adverse effect of multiples in the target structure, or to promote a favorable effect of multiples in the target structure.

    摘要: Methods, systems, and computer-readable media for analyzing a domain are provided. The method includes defining a mask plane that includes a first dimension of a first number of voxels and a second dimension of a second number of voxels, and selecting a plurality of first angles for orientating the mask plane in the domain with respect to a first axis. The method also includes for each one of the plurality of first angles selected populating, using one or more processors, sum cubes associated with each one of a first plurality of subject voxels. The method also includes selecting a plurality of second angles, and for each one of the plurality of second angles selected, calculating a planar sum for each one of a second plurality of subject voxels selected.

    摘要: A method and system are described for identifying a geologic object through cross sections of a geologic data volume. The method includes obtaining a geologic data volume having a set of cross sections. Then, two or more cross sections are selected and a transformation vector is estimated between the cross sections. Based on the transformation vector, a geologic object is identified within the geologic data volume.
