Abstract

 MCS surveys targeting deeper reflection image are increasing these days, and longer streamer cables or two ships for shooting and recording are used to try acquiring the deeper image. However, the survey with longer streamer is difficult to conduct in strong currents and ship traffic congestion. To obtain deeper reflection image, we have developed the integrated imaging method of OBS and MCS data. In shallow part, conventional MCS data is used. For deep image, wide-angle reflection OBS data is used. Moreover, the verification of the imaging method has been confirmed with synthetic and field data, and parameter tests for effective imaging have been conducted. Consequently, the reflection of plate boundary is well imaged from shallow to deep continuously, down to 20-km depth. We believe this method is an effective way to discover the new scientific information.<br>
