Well controlling multi-trace seismic deconvolution technology

Conventional deconvolution methods in reducing band-limited wavelet interference often cause lateral instability of the estimated reflectivity or impedance. In addition, conventional deconvolution processing ignores the spatial relationship between traces. Spatial regularization technique can solve the problems to some extent, but there is still lack of recovery of low frequency and high frequency and ill posed problems. In this paper, based on spatial regularization, we induced logging data and proposed wells controlling multi-trace deconvolution method. A synthetic data example and a field data example are adopted to illustrate the method effectively. After processing, the seismic data resolution is improved significantly and its spatial continuity keeps well. The result has good match with low-pass filtering of logging data. The method can provide high resolution seismic data for thin reservoir prediction.
