This ongoing project consists of the reprocessing of OBC 3D Data up to PSTM level. The scope of work includes, onsite work/support to LGC for OBC Data Summing, Statics Modeling, Prestack Noise Attenuation, Multiple attenuation, 03-Pass Velocity Analysis on 0.5x0.5 Grid, Kirchhoff Prestack Time Migration Automatic Velocity Picking for PSTM using DMI auto imaging techniques and Poststack Processing/Enhancement.
