... response in seismic velocities. Based on this fact, inversion results such as acoustic impedance, S-Impedance, Vp/Vs., Poisson ratio and other derived elastic parameters can be misinterpreted leading to locating faked prolific zones in areas where facies do not have enough quality to be considered...

... a quantitative assessment of rock properties including density, compressional velocities and porosity in a tight gas sandstone. To achieve this objective, the study develops a new relationship between Acoustic Impedance (AI) and porosity. This study focuses on a post stack seismic inversion through a band limit...

.... Significance estimation and error mapping provide a quantitative measure of confidence. Specific seismic attributes have been found to correlate well with individual reservoir properties, thus improving the ability to map them. For example, interval velocity and acoustic impedance often correlate well...

... of Acoustic Impedances by applying a constraint sparse spike algorithm. Both well data (lithology and compaction) and horizons (structural framework) help to constrain the process, thus the reflectivity series found meets the criteria of minimizing the residual between the synthetic model and the real 3D...

..., and the estimated acoustic impedance values satisfy the seismic data, in this way driving resolution to an intermediate range between the well and seismic data. With this procedure stochastic simulations of the petrophysical variables are generated, (density and lithology) that not only honour the hard data...

... analysis in the frequency domain. Events which can not be distinguished in the Fourier transformed domain may be separated in a variographic analysis and filtered by factorial kriging. Acoustic Impedance Image Factorial Kriging The acoustic impedance is a seismic attribute obtained from a seismic...

... directly obtained through compressional-wave AVAz (Amplitude Versus Azimuth9), and 3-Component shear wave analysis10. Porosity & fluid estimates are primarily supported by acoustic impedance ( Vp) inversion and facies analysis. To aid in differentiating the poststack seismic response to changes in porosity...
