Seismic Modeling
Modeling the seismic response:
Determine bulk-rock velocity and density
Calculate impedance (Recall: I = ρ x v)
Represent impedance changes as reflection coefficient
Convolve seismic wavelet to reflection coefficients
Slide 7
We can model the seismic response at the boundary between two rock units if we know the velocity and density of each unit
We calculate the reflection coefficient using the formula shown
We then use a mathematical process called convolution to model the seismic response
