Inversion for Thin-Bed Thicknesses Using Seismic Spectral Data

E-30 INVERSION FOR THIN-BED THICKNESSES USING SEISMIC SPECTRAL DATA 1 MAHER I.

We will also demonstrate other benefits arising from decomposing seismic data into different frequencies specifically the delineation of certain geological features based on resonance effects.
