Thus, a seismic wavelet broadens as it travels (Ziolkowski and Fokkema, 1986[1]). A wavelet at a given distance away from a source is visibly smoother and of longer duration than is a wavelet closer to the source. For example, in the Pierre Shale in Colorado, a tenfold loss of amplitude occurs between 10 Hz and 70 Hz, and frequencies above 100 Hz are lost substantially. Many rocks are less attenuating than the Pierre Shale. However, for any rock, inelasticity sets a limit on achievable seismic resolution.
