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,...
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 کاملExternal Inversion , Internal Inversion , and Reflection Invariance
Having in mind that physical systems have different levels of structure we develop the concept of external, internal and total improper Lorentz transformation (space inversion and time reversal). A particle obtained from the ordinary one by the application of internal space inversion or time reversal is generally a different particle. From this point of view the intrinsic parity of a nuclear pa...
متن کاملPrestack migration deconvolution
Poststack MD has been shown to be an effective method for attenuating migration noise, improving lateral resolution, and correcting for some migration amplitude distortion in 2-D and 3-D data (Hu and Schuster, 1998; and Hu and Valasek, 1999). In field data tests, poststack MD has successfully improved the 3-D poststack migration images (Hu and Valsek, 1999) obtained from both synthetic and fiel...
متن کاملReport 3 Migration Deconvolution
The migration section is the reflectivity distribution modulated by the discrete Green’s function for migration. For a poorly sampled trace distribution, the Green’s function introduces noise into the migration image that can obscure its interpretation. Using this migration Green’s function and assuming shift invariance, we propose an economical method to deconvolve the Green’s function from th...
