Surface Consistent Deconvolution

Surface consistent deconvolution uses any combination of source, receiver, offset and CDP components for power spectrum calculation and deconvolution. Theory the recorded seismic and signal may be considered as the convolution of the source signal with the instruments, the geophones, and the response of the earth. The earth response includes some undesirable effects, such as reverberation, attenuation and ghosting. The objective of deconvolution is to estimate these effects as linear filter and then design and apply inverse filters. Surface consistent deconvolution is based on the concept that a seismic wavelet can be broken down into its source, receiver, offset and CDP components. For land data, all four components are normally used in the decomposition, but only the shot and receiver portions are applied. Since the receivers are in motion in land acquisition, the common receiver grouping is less suited to this type of data. However, the common receivers domain is still important in areas with highly variable bottom conditions. When using this process on land data it is common either to perform a simple shot decon, or to use the shot and offset terms.
 
PT. GIS robust Surface Consistent Deconvolution techniques mitigate these noise effects and stabilize the solution. Source, receiver and offset terms are commonly employed for the surface consistent solution. This implementation may also be constrained to design operators on the band-limited signal component of the data only.
