    摘要: A technique includes modeling a seismic wavefield in a vertical transversely isotropic media as a second order derivative of a first wavefield function with respect to a vertical direction and not with respect to crossline and inline directions and as second order derivatives of a second wave field function with respect to the inline and crossline directions and not with respect to the vertical direction. The method includes processing seismic measurements of the media in accordance with the modeled seismic wavefield to obtain information about the media. In another technique, a seismic wavefield in a tilted transversely isotropic media are modeled based at least in part on orientation of the symmetry axis and a nonzero shear velocity for the media; and seismic measurements of the media are processed in accordance with the modeled seismic wavefield to obtain information associated with the media.

    摘要: To generate an absorption parameter model, estimated values of an effective absorption parameter are received, where the estimated effective absorption parameter values represent absorption encountered by a seismic wave in a subterranean structure. Based on the estimated effective absorption parameter values, an absorption parameter model is generated that varies absorption parameter values along at least one dimension of the subterranean structure.

    摘要: Computing systems and methods for improving imaging of collected data are disclosed. In one embodiment, a first wavefield is propagated to obtain a first wavefield history; the first wavefield is again propagated to obtain a second wavefield history, wherein the propagation includes integration of one or more Q-effects; a first attenuated traveltime history is estimated based at least in part on the first and second wavefield histories; a first Q-model filter is calculated based at least in part on the first estimated attenuated traveltime; and a first adjusted wavefield is generated based at least in part on application of the first Q-model filter to the first wavefield. In some embodiments, an image is generated based at least on a first adjusted wavefield and a second wavefield.
