Recovery of Thin Formation Properties through Seismic Amplitude Inversion

The paper proposes an effective method to recover a thin-formation structure (thinner than seismic wavelength) through amplitude inversion of surface-recorded low-frequency seismic events with due regard for downhole acoustic log data. As a result, spatial structure and properties of individual thin beds in a geologic unit are recovered between the wells at a scale less than seismic wavelength.
