Abstract In this study, the Polanyi theory was applied to investigate variation in shale gas adsorption capacity with burial depth. Analyses were implemented on background data of two shale samples with respective TOC contents of 4.00% and 4.51% TOC, accompanied by combination of the Polanyi theory and isothermal adsorption parameters. Shale gas adsorption capacity was found to first increase and then decrease as the burial depth grew, and the burial depth corresponding to the maximum adsorption...

Abstract In order to explain the rising segment of the mercury intrusion curve in the high pressure (60,000 psi) mercury intrusion tests on shales, this study implemented a series of analyses on 7 Lower Silurian Longmaxi Formation shale samples from 4 wells in the Sichuan Basin, China, including helium-based porosity, TOC abundance and X-ray diffraction. Two pressure balance time values, namely 30 s and 60 s, were used in the high pressure mercury intrusion tests. According to the results, the c...

To directly measure the gas content in the Benxi and Shanxi subformations of the Ordos Basin in NW China, a series of canister desorption tests were carried out on 33 over-mature Lower Permian to Upper Carboniferous fresh shale cores (>3000 m) at both the reservoir temperature (75–80 °C) and an elevated temperature of 95 °C. Organic chemistry and X-ray diffraction analyses of 33 replicate samples were used to establish relationships between the gas content and rock composition. Geochemical measu...

Abstract In order to clarify the influence of laminae on the gas storage capacity of the delta−front shales, this study separates the bright laminae with the dark one in the six samples from the Lower Permian Shanxi Formation, Xiasiwan Area, Ordos Basin. Various analyses are subsequently implemented, including He−porosity test, XRD test, TOC test, N2 adsorption analysis, rock−eval pyrolysis analysis, free gas test and isothermal adsorption test. It is demonstrated that the dark laminae are muddy...

Abstract In order to evaluate shale gas content more accurately, a novel method for estimation of shale gas content in place is proposed based on the Polanyi adsorption potential and the London dispersion potential energy (P-L method). A series of integrated analyses were conducted on one shale core sample from the 7th member of Yanchang Formation (Chang 7 Member) in Ordos Basin, NW China, including on-site canister desorption tests, high-pressure methane adsorption isotherms, helium-based poros...

In order to better understand the impact of fractal features of pore-throat structures on effective physical properties of tight gas sandstones, this paper carried out constant-rate mercury injection tests, gas–water permeability analyses, helium-based porosity and nitrogen pulse decay permeability measurements, and SEM and casting thin-section analyses on 20 sandstone samples of the Shihezi Formation from 16 wells of the Sulige Gas Field in the Ordos Basin, China. The fractal dimensions of pore...

Abstract Organic-rich rocks have received increasing attention for they are essential for evaluating hydrocarbon potential and unravelling the interaction between Earth surface environments and the biosphere. In this paper, we performed a combination of mineralogical, inorganic and organic geochemical analyses on a 200-m core of the Permian Lucaogou Formation organic-rich rocks obtained from Santanghu Basin, NW China, to investigate paleoenvironmental conditions, organic matter accumulation, and...

Abstract The effects of pore throat structure on gas permeability in tight sand reservoir were investigated using helium-measured porosity, pulse decay permeability, casting thin sections, scanning electron microscopy (SEM), nuclear magnetic resonance (NMR), and constant-rate mercury injection for five sandstone samples from the Upper Triassic Yanchang Formation in the Western Ordos Basin, China. Results show that permeability values are in the range of 0.474–2.290 mD. The strong variation may b...
