Perform Gassmann fluid substitution on well logs to predict fluid effects on velocities and impedance, then model AVO responses using Shuey or Zoeppritz equations. This workflow computes elastic moduli from your logs and generates synthetic seismograms across target horizons.

Yes, you can generate synthetic seismograms from LAS files. The workflow loads LAS or DLIS logs, despikes the data, derives vp, vs, and rho, and then produces synthetic traces suitable for well-to-seismic ties across target horizons.

Yes, computing elastic moduli and impedances from well logs requires lasio and welly to load and prepare logs, and bruges to perform the rock-physics calculations for K, G, E, nu, and impedances.

The best way to model AVO responses from petrophysical well log data is using an integrated rock-physics pipeline. Compute impedances from logs, perform Gassmann fluid substitution, and apply Shuey or Zoeppritz equations to generate the AVO responses.

A rock-physics workflow handles despike and QC by loading raw LAS or DLIS petrophysical logs, applying despike corrections, and deriving vp, vs, and rho curves to ensure accurate elastic moduli calculations and fluid substitution modeling.

Limitations depend on your input log quality and horizon definition. The workflow uses disba and segyio to generate synthetic seismograms, requiring properly despiked vp, vs, and rho logs to accurately model AVO responses and produce reliable synthetic traces.
