System for characterizing effective permeability for oil and water in shale reservoirs
Background Accurately quantifying how oil and water move through shale is essential for optimizing energy production from unconventional reservoirs like those in the Permian Basin. These formations present significant measurement challenges due to their ultra-low permeability, variable wettability, and the presence of microfractures. Traditional methods...

A robust tool for full in-situ rock characterization
Problem statement Pore-throat-size distribution is one of the most basic properties of porous media, which controls fluid flow and many physical properties of reservoir rocks (Fig. 1). Accurate, real-time, safe, and in-situ assessment of this property, however, has always been a challenge for the petroleum industry. Reliable assessment of this property...
