Comparing 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 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 کاملImpact 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 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 کاملNonlinear AVO inversion using geostatistical a priori information
We present a Monte Carlo based strategy for non-linear inversion of seismic amplitude versus offset data. The problem is formulated in a Bayesian framework such that the solution to inverse problem is an a posteriori probability density. A priori information about the problem is defined as a Gaussian probability density. The problem is conditioned by observations of reflected P-waveforms. A non...
