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

Tight gas reservoir (TGR) plays an important role in unconventional oil and gas resources.
The existing seepage models for TGR rarely consider the effects of heterogeneity, stress …

Anomalous diffusion concept is applied to model subdiffusive flow in heterogeneous,
nanoporous media. The basis of anomalous diffusion is discussed and interpreted for …

Flow and transport processes in fractured systems are not yet fully understood, and it is
challenging to determine the respective parameters experimentally. Studies on 10 samples …

Conventional porous-medium-flow models are not suitable for naturally fractured, nano-
porous reservoirs where the conditions of the continuum assumption do not hold. Due to the …

The molecular communication system with anomalous/fractional diffusion inside a one-
dimensional (1-D) environment is considered. The time-dependent diffusivity is incorporated …

Fractures are ubiquitous in brittle geological media, providing critical paths for pollutant
transport. Analytical solutions describing Fickian diffusion of pollutants in a single fracture or …

This study presents a one-dimensional numerical model for anomalous diffusion of three-
phase, oil-water-gas, flow in a fractured, nanoporous medium. The focus is to address the …

The diffusion kinetics of different substances in porous media is a priori described by the
second Fick's law of diffusion. Herein, we demonstrate that such a description sometimes …

On the basis of a well-based model (Model I) developed in a previous work (Liu and Valkó in
SPE J 2019. https://doi. org/10.2118/197049-PA), in which a fractional production decline …
