“…The sweetness attribute is considered one of the effective attributes to indicate sand-shale reservoirs in siliceous-clastic strata. It is defined as the root-mean-square of the ratio of instantaneous amplitude to instantaneous frequency (Alamsyah et al, 2008). Large sweetness values in seismic volumes may indicate a favorable reservoir position.…”

The boundary identification and quantitative thickness prediction of channel sand bodies are always difficult in seismic exploration. We present a new method for boundary identification and quantitative thickness prediction of channel sand bodies based on seismic peak attributes in the frequency domain. Using seismic forward modeling of a typical thin channel sand body, a new seismic attribute -the ratio of peak frequency to amplitude was constructed. Theoretical study demonstrated that seismic peak frequency is sensitive to the thickness of the channel sand bodies, while the amplitude attribute is sensitive to the strata lithology. The ratio of the two attributes can highlight the boundaries of the channel sand body. Moreover, the thickness of the thin channel sand bodies can be determined using the relationship between seismic peak frequency and thin layer thickness. Practical applications have demonstrated that the seismic peak frequency attribute can depict the horizontal distribution characteristics of channels very well. The ratio of peak frequency to amplitude attribute can improve the identification ability of channel sand body boundaries. Quantitative prediction and boundary identification of channel sand bodies with seismic peak attributes in the frequency domain are feasible.
