| | Abstract | | In recent years, the deployment of four component OBC system has provided a number of cost-effective seismic surveys with higher quality and resolution in the marine-land transition zone. The 4-C OBC system equipped with a single hydrophone and 3-C MEMS accelerometers presents various multi-component processing, including profiling of P-S converted wave, polarization filtering and de-ghost processing. In September 2008, we conducted a 2D test seismic survey using a 4-C OBC system with MEMS accelerometers in the inshore area off Nishi-Kanbara, Niigata pref., East coast of Japan. In this presentation, we demonstrate the effectiveness of seismic reflection survey with 4-C OBC system, including de-ghost processing and P-S converted wave processing. |
