oa Challenges of Marine Seismic Project in Block 15, Sudan Red Sea

During 2007 marine seismic survey, RSPOC’s contracted 2D seismic vessel equipped with 6-km length streamer cable faced several technical and operational challenges. It is quite a challenging task to process Pre-Stack Time Migration (PSTM) seismic data due to complicated seismic wave ray paths and velocity trends from two different exploration objectives. Additionally, seismic interpretation using 2D seismic dataset requires exceptional interpretation skill with sound-geological model to ensure the result represent an acceptable geological model of Red Sea rift tectonics. The latest Pre-Stack Depth Migration (PSDM) processing sequence has provided better definition of complicated Pre-Miocene Salt Formation fault pattern. With better PSDM seismic velocity dataset, bore hole formation pore pressure trend at the proposed prospect drilling locations could be estimated and predicted in effort to assist the planning of offshore high-pressure and high-temperature (HPHT) wildcat drilling campaign.
