Abstract
Frequency dependent attenuation of seismic waves that propagate through the partially fluid saturated porous rock will be observed. The new method for estimation of frequency dependent attenuation will be developed. The frequency dependent attenuation will be calculated in time-frequency domain which obtained using a spectral decomposition method based on continuous wavelet transform (CWT). The attenuation estimation method will be applied to synthetic data of reflection seismic and vertical seismic profiling (VSP) which were obtained from numerical modeling of seismic wave propagation in partially fluid saturated porous medium using parallel processing technologies based on the Graphics Processing Unit (GPU). The synthetic data of reflection seismic and vertical seismic profiling (VSP) will be transformed to time-frequency domain using continuous wavelet transform (CWT). The frequency dependent attenuation will be calculated in time-frequency domain. The result of attenuation estimation indicates that the maximum value of attenuation is present at varying frequencies and correlated with the physical properties of the partially fluid saturated porous rock.
