Abstract
Observing reflection coefficient and Acoustic Impedance (AI) from seismic section is necessary to get some geological information. The seismic section is an arrangement of many seismic traces as a result of convolution between reflection coefficient and mother wavelet. And one way to get both reflection coefficient and AI is model based inversion method. Unfortunately, it is hard calculating, consists of several steps you need to understand. Alternative way, we do this process to seismic section image as a practice. Seismic traces that extracted from seismic section has low size and it is very easy to be inverted. Anyway, it is a simple thing but can be a breakthrough in understanding model-based inversion method. It can be applied to the real data for getting a better result.
