The impact of internal multiple attenuation in pre-salt areas of Santos Basin

Abstract

The ultimate goal of seismic imaging is to provide a highquality seismic data for further interpretation and reservoir characterization. In the Santos basin, this goal can be compromised by the presence of strong internal multiples that affect the pre-salt reservoirs. Using the prediction method presented by Krueger et al. ( 2018), we examine several pre-salt areas in the Santos basin. We present our internal multiple prediction and subtraction strategies, and show the benefits for interpretation, velocity model building and quantitative analysis.
