Methods and devices for transformation of collected data for improved visualization capability

Abstract

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.

What is claimed is: 
     
         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.   
     
     
         2 . The method of  claim 1 , wherein the use of the spatial function during propagation of the second wavefield includes multiplying by the spatial function to obtain the second wavefield history. 
     
     
         3 . The method of  claim 1 , wherein the generation of the approximation is based at least in part on computing a ratio of the first and second wavefields. 
     
     
         4 . The method of  claim 1 , wherein the integration is over space. 
     
     
         5 . The method of  claim 1 , wherein the integration is over time. 
     
     
         6 . The method of  claim 1 , wherein the modification of the part of the second wavefield includes changing the amplitude of the second wavefield.
