Seismic Pitfalls Related to Converted Waves - Lebanon Offshore Case Study

Summary Conversion of P-wave to S-wave and vice versa is a well-known seismic wave propagation phenomenon which occurs when there is a high elastic impedance contrast between two layers. In basins, where a salt layer is present, the presence of converted waves is common. The case study is located in the Eastern Mediterranean see, offshore Lebanon. This presentation will highlight the similarities between a DHI and a converted wave anomaly. An easy methodology to help seismic interpreters to better identify converted wave pitfall will be described. The result of the converted wave removal applied in a recent PSDM reprocessing will also be presented.
