Prestack 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,...

Resolving 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...

Prediction using Prospect Theory

In this report, we consider prediction of an agent’s preferences over risky monetary outcomes using Prospect Theory. We suppose that for a given agent we have data on previous prospects that the agent has accepted or declined. Based on this information, we would like to predict whether the agent will accept some new prospect X∗. This amounts to learning a value function v and probability weight...

Nonlinear 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...

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...
