“…Also note that the values of the Max Pore Radius shown in Table 1 should be viewed as a maximum values (see the explanation in Section 4.3). Based on the classification scheme proposed by the International Union of Pure and Applied Chemistry (IUPAC, 1994), pores are divided into three groups based on size: macropores (>50 nm), mesopores (2e50 nm), and micropores (<2 nm) (Loucks et al, 2012;Furmann et al, 2014). Therefore, the pores observed in this study are all macropores due to the resolution limit.…”

“…Pores in shale matrix can be classified into three groups, according to the pore classification system of the International Union of Pure and Applied Chemistry (IUPA): macropores (>50 nm), mesopores (2-50 nm) and micropores (<2 nm) [2]. Recently, the characterization of the complex pore structure of shale has drawn significant attention because the pore structure not only controls the gas storage capacity but influences gas transport dynamics [3][4][5][6][7][8][9][10][11][12][13][14]. Thus, the quantification of pore structure is critical and essential to estimate the gas storage capacity and to predict gas deliverability at reservoir conditions.…”

Shale matrix pore structure controls the gas storage mechanism and gas transport behaviors. We employed various techniques to characterize the complex pore structures of 12 shale samples collected from two marine shale formations in upper Yangtze area in China. The characterization techniques include field emission scanning electron microscopy (FE-SEM), high-pressure mercury intrusion porosimetry (MIP), and low-pressure N 2 /CO 2 adsorption. The excess methane adsorption capacity was measured for each samples and results were modeled using Langmuir model. Based on the FE-SEM image analyses, micro-and meso-pores within organic matter and inter-particle pores between or within clay minerals are the most commonly developed in these shale samples. Both uni-and multi-modal pore size distributions (PSDs) were observed, and a significant portion of pores are in the pore size range between 3 and 100 nm. It was also found that the micropore (<2 nm) is the major contributor to the overall specific surface area (SSA), whereas most of the pore volume is occupied by mesopores (2-50 nm).

Lacustrine shale gas has received considerable attention and has been playing an important role in unconventional natural gas production in China.

The results show that organic matter (OM) pores are the most important type dominating the pore system, while interparticle (interP) pores, intraparticle (intraP) and microfractures are also usually observed between or within different minerals. The shapes of OM pores are less complex compared with the other two pore types based on the Image-Pro Plus software analysis. In addition, the specific surface area ranges from 2.76 m 2 /g to 10.26 m 2 /g and the pore volume varies between 0.52 m 3 /100g and 1.31 m 3 /100g. Two fractal dimensions D 1 and D 2 were calculated using Frenkel-Halsey-Hill (FHH) method, with D 1 varying between 2.510 and 2.632, and D 2 varying between 2.617 and 2.814. Further investigation indicates that the fractal dimensions exhibit positive correlations with TOC contents, whereas there is no definite relationship observed between fractal dimensions and clay minerals. Meanwhile, the fractal dimensions increase with the increase in specific surface area, and is negatively correlated with the pore size. 1840013-1
