The estimated reflectivity needs the highest reliability and resolution because of its subsequent use in the pre-stack seismic processing sequence and seismic inversion. We implemented the predictive deconvolution algorithms, the homomorphic Phase Inversion, and the Extended Kalman Filtering. Their application to synthetic traces extracted reflectivity whose comparison with well-bore allowed comparing the reliability between methods. The algorithms applied to an offshore record provided results whose comparison permitted to analyze the impact of the deconvolution assumptions on each method performance. 2022 artículo científico 0120-0283 https://www.redalyc.org/articulo.oa?id=349671141007 https://www.redalyc.org/journal/3496/349671141007/ https://www.redalyc.org/journal/3496/349671141007/html/ https://www.redalyc.org/journal/3496/349671141007/349671141007.epub https://www.redalyc.org/journal/3496/349671141007/movil 10.18273/revbol.v44n1-2022007 en http://www.redalyc.org/revista.oa?id=3496 Boletín de Geología application/pdf Universidad Industrial de Santander Boletín de Geología (Colombia) Num.1 Vol.44 |
