Shale gas permeability upscaling from the pore-scale

Pore-Scale Simulation and Sensitivity Analysis of Apparent Gas Permeability in Shale Matrix

Extremely low permeability due to nano-scale pores is a distinctive feature of gas transport in a shale matrix. The permeability of shale depends on pore pressure, porosity, pore throat size and gas type. The pore network model is a practical way to explain the macro flow behavior of porous media from a microscopic point of view. In this research, gas flow in a shale matrix is simulated using a...

Dynamic Upscaling from the Pore to the Reservoir Scale

We propose a dynamic three-stage upscaling methodology from the pore scale to the reservoir scale. In traditional upscaling approaches, simulations at smaller scales are used to compute effective transport properties that are used as look-up values in a larger scale simulation. In the proposed approach, simulations at different scales are performed simultaneously. Effective properties are found...

Experimental Investigation of Relative Permeability Upscaling from the Micro-Scale to the Macro-Scale

Upscaling geochemical reaction rates using pore-scale network modeling

Geochemical reaction rate laws are often measured using crushed minerals in well-mixed laboratory systems that are designed to eliminate mass transport limitations. Such rate laws are often used directly in reactive transport models to predict the reaction and transport of chemical species in consolidated porous media found in subsurface environments. Due to the inherent heterogeneities of poro...
