Simultaneous source or blended acquisition has emerged as a promising technology in the recent years due to its potential in increasing the efficiency of seismic data acquisition or alternatively, enhancing the wavefield sampling. Marine simultaneous source acquisition involves using two or more sources shooting simultaneously. Data processing involves the separation of the blended sources at an early stage followed by conventional signal processing. While this technology is well established in the land environment (Rozemond, 1996), its application in marine environment is relatively new. Although the simultaneous shooting concept for the marine environment was introduced in 1997 (Beasley, 1997), its commercial implementation in towed streamer and seabed environment is more recent (Kim et.al. 2009; Moore et.al. 2012; Abma et.al. 2012). The application of the simultaneous source acquisition in four-component full wave imaging is more challenging considering the complexity involved in the de-blending of PS converted wave data.
