Abstract

Processing seismic data to extract information in addition to the structural configuration requires careful attention to the effect the processing sequence has on the trace attributes of phase, frequency and amplitude.

This paper is primarily concerced with processing noisy onshore data to produce relative amplitude stack sections.

Particular emphasis is given to compensation for near-surface effects on trace amplitudes. The derivation of compensation scalers from the data is demonstrated. The application of these scalers alone will produce a relative amplitude stack section, but if significant noise is present, the stack will not have the optimum signal-to-noise ratio. The combination of compensation scalers and power diversity stack is shown to produce a good relative amplitude stack.
