The Seismic Signature of Turbiditic Channels Using Outcrops Analogs and Process-Based Simulations, from the Pab Sandston

The fine-scale architecture of turbiditic channels has been restored from the outcrops of the Pab sandstone in Pakistan. A 3D model was constructed from the outcrop interpretation and then informed in facies, petroacoustic and petrophysical properties. The model was used to calibrate process-based simulations reproducing the distribution of the heterogeneity at a fine-scale. Seismic simulations were then performed from the outcrop models and from the block issued of the process-based simulations. The effect of the small-scale heterogeneity on the seismic signature was then analysed and compared to real case-studies in subsurface.
