Geophysical equations and rock physics calculations for seismic analysis.
Use when the agent needs to: (1) Calculate AVO responses (Zoeppritz, Shuey, Aki-Richards),
(2) Perform Gassmann fluid substitution, (3) Generate seismic wavelets (Ricker, Ormsby),
(4) Compute reflectivity and synthetic seismograms, (5) Calculate elastic moduli from
velocities, (6) Apply Gardner/Castagna empirical relations, (7) Model rock physics effects.
