Introduction
The Development of an environmentally sustainable method for the extraction and processing of Rare Earth Elements (REE) is an ongoing study as the state of the art exploration like e.g. in China leads to a significant impact to the environment in terms of water pollution, destruction of the biosphere and erosion. For a mining project in Madagascar it is therefore...

Multi-scale nature is one of the key features in complexity of rock structures from unconventional resources. Advanced imaging techniques such as high resolution Computed Tomography (CT) and Focused Ion Beam–Scanning Electron Microscopy (FIB-SEM) have shown that these low permeability rocks possess bi-model pores distribution. To characterize the inter-particle and intra-particle pores and...

Pore-scale flow modeling based on pore network model is an efficient simulation method. However, the distribution of two-phase fluid in pores and throats is based on the two-phase numerical simulation results in a single channel during the simulation of two-phase flow. The influence of pore-throat topology and pore-throat ratio cannot be considered. Hence, a new pore doublet model is proposed,...

With the advancement of multistage hydraulic fracturing technology, hydrocarbon production from tight reservoirs has exploded recently. Owing to its widespread nanopore, the permeability of tight sandstones are typically ~4 orders of magnitude smaller than conventional formations, thus leading to the breakdown of Darcy’s law within the complex nanoporous matrix. However, most of the existing...

The organic and inorganic pores exhibit significant differences in pore sizes and surface chemistries that give rise to complex fluid flow behaviours. It is well known that pore size and pore connectivity directly impacts on macroscopic flow properties of a porous medium. Therefore characterization of strong heterogeneous shales with multiscale pore size is indispensable to accurately assess...

Rock typing is an essential step in reservoir characterization and geological model building for reservoir simulation. Conventionally porosity, permeability and capillary pressure data of coring core samples are used to divide rock types. With developing of high-resolution imaging equipment, micro-structure parameters are able to be quantified and wildly used in the research of reservoir...

Stress-dependent permeability and capillary force play important roles in determination of flow characteristics in fractures.Traditional empirical equations for relative permeability cannot accurately reflect transport behavior in rough fractures in consideration of normal deformation. In this paper, a systematic approach has been proposed to determine flow properties, such as relative...

The storage and seepage of oil and gas in the reservoirs are controlled by pore size distribution, pore shape, pore throat and connectivity. Pore structure is of vital use for understanding and evaluating the storage and seepage properties of low-permeability reservoir. Fractal theory is considered as an effective method to describe the heterogeneity of pore structure.
