METHODS AND DEVICES FOR TRANSFORMATION OF COLLECTED DATA FOR IMPROVED VISUALIZATION CAPABILITY

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.

1. A method, comprising:
propagating a first wavefield to obtain a first wavefield history; generating a first image based on the first wave-field history; propagating a second wavefield to obtain a second wavefield history, wherein the propagation includes modification of at least a part of the second wavefield through use of a spatial function, wherein the spatial function is configured to generate an approximation to an integral of a selected function over a wavepath corresponding at least in part to the first wavefield, and wherein the propagation of the first and second wavefields use substantially the same starting conditions; and generating a second image based on the second wavefield.
