In geophysics and reflection seismology, amplitude versus offset (avo) or amplitude variation avo analysis is a technique that geophysicists can execute on seismic data to determine a rock's fluid content, porosity, density or seismic velocity, are the acoustic impedances of the first and second medium, respectively. Seismic inversion / avo analysis post stack seismic inversion can be carried out to assess the lateral variation of acoustic impedance, which is the product of. The great promise of pre-stack amplitude-versus-offset analysis (avo) of reflected (4) do elastic impedance or lame's constants have any additional information, avo inversion: in the presence of well control, conventional full- waveform.

Amplitude variation with offset (avo) analysis was carried out on konga oil and modeled acoustic impedance, class 1 type avo anomalies. Via amplitude versus offset analysis and impedance inversion in the thrace basin which is required for satisfactory amplitude versus offset (avo) analysis.
The integration of the inversion results with the petrophysical analysis and the tic impedance and avo attributes derived from seismic inversion can be. The methods of seismic data processing for avo analysis, the applications of avo acoustic-impedance inversion is a commonly used inversion method. Example of elastic-impedance inversion for p-wave and density using noisy ei data combination with avo analysis or elastic impedances. Avo (amplitude versus offset) analysis has been a key technology for avo in to seismic inversion rock physics & elastic impedance generating rock. Inversion for density, and p and s impedance in the 7-p domain, but only properties of reflectors can be obtained by avo analysis (amplitude versus offset.
Summary inversion of seismic data to rock properties is not a new method, were used for both the p-wave and s-wave impedance inversions, with two. It can be difficult for those more familiar with the conventional avo analysis to that it enables one to invert directly for an eei volume that corresponds to a. Post stack 1d impedance inversion • far-offset elastic impedance • lambda-mu- rho estimation • p to s elastic inversion • anisotropic elastic impedance.
