Rock Property Inversion in Organic-Rich Shale: Uncertainties, Ambiguities, and Pitfalls
Kaushik Bandyopadhyay,Ratnanabha Sain,Enru Liu,Christopher E. Harris,Alex Martinez,Michael A. Payne,Yaping Zhu +6 more
TL;DR: In this paper, the authors used the seismic measurements to estimate the acoustic impedance and Vp/Vs ratio of organic-rich shales, and the anisotropic elastic properties with varying degrees of measurement errors.
Journal ArticleDOI
How computational rock-physics tools can be used to simulate geologic processes, understand pore-scale heterogeneity, and refine theoretical models
TL;DR: In this article, a set of tools can be used to simulate geologic processes and interpret their signatures in the geophysical cross-property domain by computing macroscopic properties on a common or shared rock model.
