Several studies have been performed to model the storage and transport in organic matter
present in shale gas. However, the unconventional formation does not only contain organic …

In the last decade, numerous approaches, eg, analytical and semi-analytical pressure
solutions, production decline curve, reservoir-scale numerical models, have been used to …

Darcy law has been widely used in high permeability formations; however, it fails to
realistically describe different flow processes other than the viscous flow. Several …

We present an apparent diffusion coefficient derived from a diffusion-based mass
conservation equation for single-component gas transport in nanoporous media. Multiple …

Diffusion tortuosity is an important microstructural parameter for computing effective gas
transport coefficients in porous media. In this study, a realistic kerogen structure was built to …

The recently-discovered promise of shale-gas reservoirs necessitates their characterization.
As a first step, two-dimensional (2D) scanning electron microscope (SEM) imaging can …

Gas transport in ultra-tight rock is non-Darcian. In addition to continuum flow, there are
multiple other flow mechanisms such as slip flow and pore and surface diffusion. Various …

Multiple gas transport mechanisms and geological parameters influence total gas
production in hydraulically-fractured organic-rich shale reservoirs. The absolute and relative …

Understanding the integrated transport behavior of oil in shale nanopores is critical to
efficient shale oil development. In this paper, based on the time-dependent Poiseuille flow …

Shale samples consist of two major components: organic matter (OM) and inorganic mineral
component (iOM). Each component has its distinct pore network topology and morphology …
