Interval velocity seismic
WebWe assume horizontal velocity layering so that the values of in Table 5.15a are approximate values of (see Table 5.12b) and therefore we can use equation (5.15b) to find interval velocities. We take 2.18 km/s as the interval velocity from the surface to the … WebFeb 17, 2024 · Seismic velocity is a function of the density and strength modulus of the rocks through which the energy passes. Both density and strength are affected by abnormal pore pressure. Seismic profiles that show unusually slow interval velocity may indicate an undercompacted (overpressured) interval. Unusually fast interval velocity, conversely, …
