Source And Receiver Amplitude Equalization Using Reciprocity - Application to Land Seismic Data

摘要: Source and receiver amplitude equalization is necessary when their behavior changes with location within a given survey. Preferably, these corrections are performed in the early stages of processing. However, existing techniques which account for effects, such as surface-consistent deconvolution, applicable to primary reflection data only. Therefore, require prior We developed an alternative method compensate source perturbations has advantage being purely preprocessing step. It whole seismic trace, no assumptions imposed on subsurface. The based reciprocity medium response. As result reciprocity, differences between normal reciprocal recordings can be attributed perturbations. applied this technique single-sensor acquired Manistee County, Michigan. At site, near-surface conditions vary, significantly affects quality. application procedure led significant improvement signal-to-noise ratio, both prestack poststack data.
