Summary:
Seismic attenuation is an important parameter to understand and parameterise, with implications for survey design, processing, interpretation, and inversion. Here we present a brief summary of the physical theory underpinning our understanding of attenuation and illustrate how this can be used to compensate for the loss of energy within a data processing workflow, preserving vertical resolution down-trace. Furthermore, we discuss the potential uses of attenuation as a parameter for characterising the nature of the subsurface, suggesting that attenuation should be perceived in a more positive light and seen as another parameter (alongside amplitude, phase, and move-out) that provides valuable quantitative information.
