Integrated geological and geophysical study was carried out using newly acquired 3D seismic data in order to evaluate further exploration potential for sandstone pinch-out traps, offshore Kitakanbara, Niigata, Japan. The 3D seismic PSTM negative amplitude was useful for predicting the sandstone distribution in spite of the dominant frequencies as low as 10-12Hz. Depositional systems of the turbidite successions were estimated in sequence stratigraphic framework by integrating thickness, seismic amplitude and seismic facies maps which were calibrated with depositional facies associations defined in the wells. A deductive hydrocarbon migration simulation was then carried out for the purpose of migration and seal risk assessment. The study highlighted hydrocarbon accumulation to sandstone stratigraphic traps in downdip portion of structural highs. During a series of study, Stratimagic and MPath applications played an important role as new technology tools for seismic facies mapping and hydrocarbon migration evaluation, respectively, especially in combination with 3D seismic data.
