Abstract:
1. A method of optimizing the separation of composite seismic data that includes signals from two or more seismic sources wherein the method comprises: a) acquiring seismic data to create a data set for a survey area; b) identifying an initial source wavelet; c) identifying an expected response to the initial source wavelet by one or more seismic receivers taking into consideration the geometric relationship of the receivers to the source; d) creating a computed earth response for each source and receiver pair based on the geology between the source and receiver; e) apply the computed earth response to the expected response to the initial source wavelet to create a source true estimated wavelet for each source receiver pair; and f) using the source true estimated wavelet for at least one further processing step of the acquired data set such as inverting, separating, de-signaturing or wavelet de-convolving.
