Journal ArticleDOI
Pore structure characterization for organic-rich Lower Silurian shale in the Upper Yangtze Platform, South China: A possible mechanism for pore development
TL;DR: In this paper, a combination of field emission scanning electron microscopy (FE-SEM), low pressure N 2 /CO 2 adsorption and mercury intrusion porosimetry (MIP) measurements was conducted to characterize the pore structure and the effects of organic matter and inorganic minerals on porosity were discussed.
Journal ArticleDOI
Productivity or preservation? The factors controlling the organic matter accumulation in the late Katian through Hirnantian Wufeng organic-rich shale, South China
TL;DR: In this paper, the authors integrated detailed geochemical analyses based on the core samples from three boreholes which are located in the outer-, middle-and inner-shelf of the Upper Yangtze platform, in order to investigate the depositional environments during the deposition of the Wufeng Formation.
Journal ArticleDOI
Mechanism of shale gas occurrence: Insights from comparative study on pore structures of marine and lacustrine shales
TL;DR: In this article, the pore structures of marine and lacustrine shales were characterized and the effects of organic matter abundance, maturity and inorganic minerals on porosity were investigated.
Journal ArticleDOI
Investigation of methane sorption of overmature Wufeng-Longmaxi shale in the Jiaoshiba area, Eastern Sichuan Basin, China
TL;DR: In this paper, the supercritical Dubinin-Radushkevich (SDR)-based and the Langmuir-based excess adsorption models are used to fit measured adsore isotherms.

Morphology, Genesis, and Distribution of Nanometer-Scale Pores in Siliceous Mudstones of the Mississippian Barnett Shale
TL;DR: In this article, the authors used scanning electron microscopy to characterize the pore system in the Barnett Shale of the Fort Worth Basin, Texas, showing that the pores in these rocks are dominantly nanometer in scale (nanopores).
Journal ArticleDOI
Spectrum of pore types and networks in mudrocks and a descriptive classification for matrix-related mudrock pores
TL;DR: In this paper, a pore classification consisting of three major matrix-related pore types is presented that can be used to quantify matrix related pore and relate them to pore networks.

From Oil-Prone Source Rock to Gas-Producing Shale Reservoir - Geologic and Petrophysical Characterization of Unconventional Shale Gas Reservoirs
TL;DR: In this paper, total organic carbon (TOC), maturity level (vitrinite reflectance), mineralogy, thickness, and organic matter type are used to classify organic matter that ranges from oil-prone algal and herbaceous to gas-prone woody/coaly material.
