Impact of Migration Deconvolution on AVO Inversion
Reflection amplitude as a function of offset is effective in characterizing lithology in oil producing basins. Experience shows that AVO inversion methods based on amplitude-preserved prestack migration typically provides a more accurate lithology estimation than NMO-based AVO analysis. However, some artifacts may be introduced into the migration section, which can obscure the estimate of reser...
متن کاملPrestack migration deconvolution+AVO inversion
Measuring reflection amplitude versus offset (AVO) has proved to be effective in reservoir characterization. Experience shows that AVO inversion methods based on amplitude-preserved prestack migration typically provides a more accurate lithology estimate than NMO-based AVO analysis. However, some artifacts may be introduced into the migration section due to an undersampled acquisition geometry,...
متن کاملResolving Ambiguity in AVO and AVAz Inversion
The AVO and AVAz contain valuable information about the elastic properties of a subsurface media. However, the conventional approaches are based on plane-wave theory, which cannot explain observations near the acoustic critical reflection and far offset null reflection at Rayleigh angle. In this contribution, we show our algorithm to understand the acoustic reflectivity of liquid-solid boundary...
متن کاملComparing Post-stack AVO Inversion to Prestack Inversion for Estimating Rock Properties
Inversion of seismic data to rock properties is not a new method, however there are a wide variety of methodologies available one can use to achieve those estimates. The number of potential AVO equations one has access to now exceeds what many would consider useful. The problem then becomes, which of the several methods should be applied, given a specific exploration or development goal? While ...
متن کاملComparing Geostatistical Seismic Inversion Based on Spectral Simulation with Deterministic Inversion: A Case Study
Seismic inversion is a method that extracts acoustic impedance data from the seismic traces. Source wavelets are band-limited, and thus seismic traces do not contain low and high frequency information. Therefore, there is a serious problem when the deterministic seismic inversion is applied to real data and the result of deterministic inversion is smooth. Low frequency component is obtained fro...
