Patent number: 10295688Abstract: A method for removing internal multiples from collected data, such as seismic data. The method includes predicting internal multiples for each horizon in a plurality of horizons that created the internal multiples. The internal multiples may be predicted from the seismic data in one pass. After predicting the internal multiples, the method includes creating a separate model of internal multiples for each horizon based on the predicted internal multiples for each horizon. The method then iteratively subtracts each separate model of internal multiples for each horizon from the seismic data.Type: GrantFiled: May 23, 2011Date of Patent: May 21, 2019Assignee: WESTERNGECO L.L.C.Inventors: Adriana Citlali Ramirez-Perez, Alan G. Teague, Milton A. Walz, Zhiming Wu
