Abstract
An important problem in seismic data processing is to improve the temporal resolution and to estimate the white reflectivity series (spiking deconvolution). Minimum phase filter is normally applied like conventional procedure in the deconvolution of seismic data. The deconvolution sometimes produces a poor result because the natural wavelet estimate is non minimum phase. This paper shows an analysis procedure with mixed phase filter deconvolution. The main propose to show is how to obtain mixed-phase inverse filters and the corresponding wavelets estimated from a minimum-phase wavelet, It filter is decompose in causal and anti-causal components, also was tested several inversed filter in the data with a parameter in the filter estimation. Finally we tested several wavelets estimated and filters for the deconvolution.
