The organic petrology of graptolites and maturity assessment of the Wufeng–Longmaxi Formations from Chongqing, China: Insights from reflectance cross-plot analysis

open access: yesInternational Journal of Coal Geology, 2017
The Wufeng–Longmaxi Formations (Ordovician-Silurian) contain abundant graptolite-bearing shales, which have proven to be one of the most successful shale gas exploration targets in China and can provide an opportunity to study the organic petrology of ...

Characterization and origin of the Silurian Wufeng-Longmaxi Formation shale multiscale heterogeneity in southeastern Sichuan Basin, China

Interpretation, 2015
Abstract Shale heterogeneity is important for micro- to macroscale-quality reservoir prediction. We evaluated the multiscale heterogeneity in shale based on thin-section observation, field emission scanning electron microscope observation, low-pressure N2 adsorption analysis, mercury intrusion porosimetry, organic carbon analysis, and

Shale gas‐bearing capacity and its controlling factors of Wufeng–Longmaxi formations in northern Guizhou, China

Geological Journal
Great progress has been made in marine shale gas of Wufeng–Longmaxi formations in the Sichuan Basin. However, shale gas exploration in the complex structural belt around the Sichuan Basin still faces great challenges. In this study, shales of Wufeng–Longmaxi formations collected from the northern Guizhou were taken as the studied target, organic matter

Quantitative characterization of nano-scale pores in shale reservoirs of Wufeng-Longmaxi formation based on image processing

2020
In this paper, we conducted image processing on FE-SEM images of representative shale samples from WX-1 well in the north-east Chongqing area. The structural parameters and proportions of major pore types were determined and analyzed following a workflow consisting of nano-scale images acquisition, image processing, pore-network evaluation and ...
