Abstract
A method for estimating source wavelet for seismic survey includes multiple steps. First, seismic data are collected using seismic data recording sensors and well log data are collected using a well logging tool in a well site in a survey region. The seismic data and the well log data are stored and processed in a computer system. The time-migrated seismic data thus collected and processed is the observed data. The well log data is processed to obtain one or more earth models that represent one or more formation properties; reflectivity modeling is performed to obtain a reflectivity, a band pass filter and time-migrated reflectivity to produce a band-limited reflectivity; the band-limited reflectivity is cross-correlated with the observed data to obtain a weight; and inversion is performed to obtain a source wavelet based on the weight, the reflectivity, and the observed data.
