The impact of wavelet estimation in 4D inversion – an offshore Brazil case study

Back to Technical Content
The 4D global inversion workflow is a multistage process that includes seismic data preconditioning, wavelet estimation, low-frequency model building, 3D inversion, and finally a 4D global inversion. In this work, focusing on a post-salt turbidite reservoir in the Campos Basin, offshore Brazil, we show how this process can help to better understand the 4D seismic data, bringing a significant uplift in the quality of the mapping of the 4D anomalies.
