摘要：Computing systems and methods for improving imaging of collected data aredisclosed. In one embodiment, a first wavefield is propagated to obtain a first wavefieldhistory; 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 secondwavefield histories; a first Q- model filter is calculated based at least in part on the firstestimated attenuated traveltime; and a first adjusted wavefield is generated based atleast in part on application of the first Q -model filter to the first wavefield. In someembodiments, an image is generated based at least on a first adjusted wavefield and asecond wavefield.
