Why do we need seismic post-stack inversion methods for reservoir characterization?
These attributes help to understand lithology and fluid contents in the subsurface. The objective of this research is to use several standard seismic post-stack inversion methods for reservoir characterization and compare their results.
What is the difference between post-stack and pre-stack inversion results?
Because of different input seismic data, results of post-stack and pre-stack inversion are not the same. Pre-stack inversion result is clear to thin layer and reflects lateral change of sandstone. Post-stack inversion result is poor in these aspects. And the inversion results are used in lithologic reservoir characterization.
What is post-stack inversion?
Post-stack techniques of inversion usually refer to the different workflows used to convert stacked seismic information into parameters of quantitative rock physics. The result is generally acoustic impedance from post-stack inversion, while pre-stack inversion can result in acoustic impedance as well as shear impedance.
What is post-stack seismic inversion?
Post-stack seismic inversion has been widely used in facies discrimination and reservoir characterization (Das et al., 2017;Erryansyah et al., 2020; Maurya and Sarkar, 2016; Qiang et al., 2020;Toqeer et al., 2021). A model-based impedance inversion approach was used to invert the post-stack seismic data.
What are the deterministic methods of post-stack inversion?
Sparse spike inversion, model-based inversion, recursive inversion, and colored inversion are the techniques of post-stack inversion. All of these techniques are grouped together as deterministic methods because they do not require probabilistic interventions.
What is post stacking acoustic inversion?
The first technique, Post-Stacking inversion is the most common approach used for inversion. This technique transforms a single seismic information volume into an acoustic impedance volume by using seismic data, well data, and basics knowledge in stratigraphy for interpretation.
