The objectives of the proposal are to develop methods for obtaining realistic configurations of two immiscible fluids as a function of wettability and geologic characteristics and use these fluid configurations as a basis for predicting and explaining macroscopic (core-scale) behavior, including the relationship between relative permeability, wettability and laboratory and log measurements of NMR and broadband dielectric response. The ultimate objective is to measure dielectric and NMR responses in a range of sedimentary rocks and to use state-of-the-art multi-scale modeling to interpret these measurements to quantify wettability and relative permeability at the core and log scales.
