Seismic reflection images across the northern Santos Basin, offshore SE Brazil

Seismic reflection images used in this study were released by the China National Petroleum Corporation (PetroChina).  Three 2D post-stack time-migrated seismic profiles (L1, L2 and L3) crossed the northern Santos Basin in an NNW-SSE direction and recorded up to 12 s (Two-way travel time, TWTT) . Four post-stack depth-migrated seismic images with short distances are extracted from the 3D seismic data. The dominant frequency is 30 Hz with a vertical resolution of 20 m. Details of the seismic processing flows were not available in this study.
