Knowledge of shale pore structure characteristics is crucial to understand gas
storage and seepage mechanisms. Organic matter (OM) pores are considered
the most important pore type in shale, and one of the currently significant
research questions focuses on the spatial distribution and connectivity of OM
pores. To answer this question, typical OM‐rich siliceous shale samples from
the Lower Silurian Longmaxi Formation were comprehensively investigated

Advances in imaging have made it possible to view nanometer and sub-nanometer structures that are either synthesized or that occur naturally. It is believed that fluid dynamic and thermodynamic behavior differ significantly at these scales from the bulk. From a materials perspective, it is important to be able to create complex structures at the nanometer scale, reproducibly, so that the fluid behavior may be studied. New advances in nanoscale-resolution 3D-printing offer opportunities to ach... Read more

Generating an accurate reservoir model is of critical importance in forecasting the lifespan of hydrocarbon reservoirs and estimating the efficiency of carbon capture and sequestration. One critical parameter controlling the flow of fluids within subsurface reservoirs is the fraction of effective or connected pore spaces in the reservoir. […]

To quantify the connectivity of the pore space, it is therefore necessary to combine high resolution visualization of pore spaces with bulk... Read more

Pore-scale two-phase flow modeling is an important technology to study a rock’s relative permeability behavior. To investigate if these models are predictive, the calculated pore-scale fluid distributions which determine the relative permeability need to be validated. In this work, we introduce a methodology to quantitatively compare models to experimental fluid distributions in flow experiments visualized with microcomputed tomography.

First, we analyzed five repeated drainage-i... Read more
