Well log data from Wells B4 and D1, highlighting the depth intervals used for estimating elastic properties. Well B4 (top): Logs of density, P-wave velocity (\(V_P\)), S-wave velocity (\(V_S\)), \(V_P/V_S\) ratio, and porosity (PHI). Well D1 (bottom): The same set of logs is shown for well D1. Red markers and green dots highlight selected depth intervals and data points used for calibration and validation of predictive models.
