f Zero-phasing marine data using one-parameter phase filters and kurtosis maximization

A.purely empirical approach that has been used to the seismic and well data is to apply a set of trial phase rotations to the seismic data. With certain provisos on data requirements and available bandwidth such an approach can be automated by using a maximum kurtosis criterion to select the desired phase correction (White, 1986). Whilst there is no apparent theoretical reason why phase rotations alone should be sufficient to zero-phase processed seismic data, this very simple procedure can be surprisingly effective in many cases. In this paper we explore the physical justification for such a one-parameter phase-scan in terms of the nature of the error arising out of conventional deconvolution processing. We derive another set of one-parameter phase filters that are physically more meaningful and also allow zero-phasing of marine data through kurtosis maximization.
