Slide 11: Seismic 2D: vertical adjustment
Seismic 2D: vertical adjustment Landmark in seismic is not consistent with elevation map • The nominal datum of 1800m- msl, the nominal replacement velocity of 3400 m/s are inconsistent with the actual elevations of the wells, seismic surface and digital elevation map of the area. The seismic sectio
Slide 12: 3D Cube Vertical Adjustment
3D Cube Vertical Adjustment Terrain elevations in the 3D cube show two problems: • The surface elevation profile was exaggeratedly smoothed for seismic processing • There is an average downward shift of the actual elevation map. On average the true elevations are displaced down from respect to the u
