Conventional wisdom for NMR interpretations of water-saturated porous media is that the NMR spectra are analogous to the pore size distribution of the system. This is the basis for understanding porous media as containing large vs. small pores, and is used as a justification for NMR-based permeability correlations. However, there are cases whereby issues of poor connectivity between pores can s...
Capillary pressure (Pc) curves acquired using the Magnetic Resonance Imaging (MRI) technique, call GIT-CAP, have 70-100 data points. This extra data, when compared with traditional porous plate or centrifuge techniques, allows for the interpretation of more information from the Pc curve. In particular, the pore throat size and relative permeability can be extracted. The pore throat size can be ...
Extension of the effective stress concept to unsaturated soils has been a major concern for decades. Recent studies significantly contributed understanding fundamentals behind Bishop's parameter χ, which is generally used define soils. An examination recently proposed methods showed that contribution suction was often overestimated, especially in high range. In this study, considering soil pore...
