| Summary, etc. | In an attempt to reconstruct the near-surface velocity for the shallow subsurface in the area under study using two different approaches: 3D Traveltime Tomography and Dispersion Curves Inversion (DCI), a total of 26286 shot records were used from Matruh 3D onshore seismic survey. The results clearly demonstrated that both models showed similar velocity behavior in the first 100m, however, DCI output model exhibited a high velocity layer (100 m thick) with velocities up to 5000 m/s between depth (-100 m and 0 m) compared to slower ones in the tomographic model within this depth interval. The validity of the two output near-surface models was tested through direct calculation of static corrections and running pre-stack depth migration (PSDM) on seismic test line(s) |
