Migration Using a Transversely Isotropic Medium with Symmetry Normal to the Reflector Dip

Figure 2

The impulse response for the prestack DTI phase-shift migration of 5 pulses at zero offset in a vertically inhomogeneous DTI model with 𝑣(𝑧)=1.5+0.6𝑧km/s and 𝜂=0.2 and 𝛿=0. The three sections represent slices in the prestack cube with the black lines representing the location of these slices relative to each other. As a result, the section on the right is simply the angle gather at distance 4 km.
